ABSTRACT

This report documents the initial phases of the Materials Information for

Science and Technology (MIST) project jointly supported by the Department of

Energy and the National Bureau of Standards. The purpose of MIST is to

demonstrate the power and utility of computer access to materials property

data. The initial goals include: to exercise the concept of a computer

network of materials databases and to build a demonstration of such a system

in a way to be suitable for use as the core of operational systems in the

future. Phases I and II are described in detail herein. In addition, a discussion is given of the expected usage of the system.

PART A - Description of Phases I and II

I. INTRODUCTION.

The Materials Information for Science and Technology (MIST)

Project is a demonstration of the power and utility of computer access to

materials property data. Several years ago, following a series of wellpublicized meetings and studies, it became apparent that the time had

come to build a prototype system so that the user community could see the

advantage of such a system and through feedback sharpen their concept

of what such a system should be able to provide.

Consequently, in late 1983, the Office of Standard Reference Data

(OSRD) of the National Bureau of Standards (NBS) and the Office of

Scientific and Technical Information (OSTI) of the U.S. Department of

Energy (DOE) began cooperating to build the MIST demonstration. Within

DOE, the MIST Project is one component of a broader Scientific Information Research Program (SIRP).

The MIST Project has two initial goals:

o To demonstrate the concept of a computer network of

materials databases

o To build a prototype demonstration system in such a way as to be

suitable for use as the core of operational systems in the future.

The basic goals of the two sponsoring groups (DOE and NBS) are the same;

that is, to provide access to materials information for technical decision-making in the most complete and efficient manner.

However, the emphases and audiences are different:

For OSTI, to meet the DOE mission through provision

of supporting technical information activities;

For OSRD, to provide a general data access capability

to the technical community at large.

Since the demonstration project started, other groups have begun

to participate, albeit often informally. These include the National

Materials Property Data Network Inc., known as the MPD Network - a nonprofit private-sector effort; the U.S. Army Command (LABCOM); and the

NASA Marshall Space Center.

When the project began in 1985, a unique opportunity existed

which all the participating groups wished to exploit. User needs had

been well identified and enthusiasm was strong among a substantial

user community. Equally important, efforts up to that time had not

progressed very far. Consequently, the time was ripe for a cooperative

concerted effort directed towards the goals outlined above.

1
THE CONCEPT

The concept of a computerized materials data system has evolved

over the last five years as computer technology has improved and as

understanding of materials information and its use has increased.

The current form of the concept is founded on several basic assumptions:

1 . The people who will build machine-^readable materials

databases are the same as those who currently write books,

compile handbooks, etc.

2. Most of these groups will not want to provide access

services to users via their own computers; or if they do

provide access, will not want to provide the traditional

support services that are required with a computer-based

product

.

3. Most engineers who use materials data currently have to deal

with a multiplicity of data sources.

4. Most engineers will soon have a computer equipped with

communication hardware and software at their desks which

can be used to access external electronic networks.

5. Most people are unwilling to learn to use a large number

of computer languages, command systems, file structures,

etc.

The concept adopted to meet such broad requirements is often

called a GATEWAY system. In this system, a user should ultimately

be able to access, via a single telecommunication connection, many

databases, even when these databases reside on different computers.

Using a single command language, or by menu screens, and through the

use of directories, thesauri, etc., users can quickly gain awareness

of what data are available. Connection to different desired databases

will be handled automatically by the gateway. After data are retrieved,

it will be possible for the user to manipulate, analyze, and display

them in a uniform way. Eventually it is conceivable that multiple

gateways will exist, reflecting the needs of different user groups.

THE CHALLENGES

The concept of gateways to distributed database systems is of

interest for many computer applications ranging from the insurance

industry to scientific data. Each application must overcome two sets of

challenges: (1) linkage of diverse computer software and hardware; and

(2) integration of information, especially that produced by different

people or organizations.

2
For material data systems, the major challenges related to the

integration of materials information are given in Table I, and in

Phases I and II of the MIST project, effort will be concentrated on

meeting many of these challenges, as outlined in this overview.

and software is not included. See Chapter III (and especially Table 2)

below for a more detailed discussion of implementation plans.

II. PURPOSE OF THE PROJECT OVERVIEW

A demonstration project such as MIST cannot simultaneously address

all the challenges listed in Table 1 . During the initial part of the

project, several detailed planning sessions were held to identify the

most important challenges and to estimate levels of effort needed to

overcome them.

This description of the first phase of the project is intended to

define the scope, both in terms of the challenges and goals, as well as

in terms of the work program itself. The chapters in Part A outline

the goals, challenges, and project participants for Phases I and II;

the second part presents general considerations about projected uses and

capabilities of the MIST system.

Development of the MIST prototype system includes a strong effort

to obtain user input and feedback on all aspects of the system. Well

before system development began, one of the first activities undertaken

was to collect information from users by way of a questionnaire

supplemented by personal interviews and focus group sessions. A copy of

the current version of the questionnaire is given in Appendix A. The

results from the questionnaire are reflected in the initial system

described here, and further user feedback will be incorporated in

subsequent revisions. This document, in turn, can be used to:

a) check for possible distortions in the understanding

by the system developers of user wants and needs

b) provide a vehicle for feedback from those individuals

who may be asked to test the validity and reasonableness

of the MIST prototype.

III. OBJECTIVES OF THE SCIENTIFIC INFORMATION RESEARCH PROGRAM (SIRP)

AND OF THE MIST PROJECT

A. General

The long-range objective of the Scientific Information Research

Program is to ascertain whether a standardized source of factual, scientific

information, maintained at distributed sites by local experts, can have a

positive impact on the productivity of scientists and engineers. The proto-^

type Materials Information for Science and Technology (MIST) system thus is

being developed based on an analysis of how a substantial group of DOE scien-*

tists and engineers use computers in their daily work. In order to begin to

assess impacts on productivity, the demonstration system needs to be used by

a group of users as an everyday tool.

However, it is important to make sure that the initial system will

not be judged against a conceptualized full-blown system, but against its

stated demonstration goals. The measure of success for MIST should be that

an average search for information on specified materials and properties in

the system results in full retrieval of the information stored, presented

in a format intelligible and convenient to the user. If expanded to a com-5- prehensive database system (in terms of the needs of the user community), it

would become the preferred information source because of demonstrated im-*

provements in user productivity.

Because of the complexity of the complete description of engineering

materials and their mechanical and corrosion properties, and because existing

material databases have user interfaces which neither fully exploit the power

of computers nor are particularly attractive in format or convenience, spe-^

cial emphasis has been placed on the challenges related to the materials data

content and its organization and use. The aspects of the gateway concept not

being considered in phases I and II relate to computer science issues of

networking and physically and logicallydistributed databases maintained on

different kinds of computers. These issues are receiving intense study from

other sources. The MIST project will adopt results as developed eleswhere.

Initially, the MIST project will provide access to physical and

mechanical properties of metal alloys, the most commonly needed information,

as a first step to accessing data on a wide range of properties for all

classes of materials. The choice of the class of materials for the initial

system was easy. Only for metallic alloys does a critical mass of highly

evaluated data exist. Also, the nomenclature and designation of metallic

alloys, while still imprecise in many respects, has advanced far enough in

standardization to be used in a general access computerized database system.

5
B. Specific Initial Objectives of Phases I and II

The above considerations led to the following specific initial

objectives:

1 . Establishment of a User Group

A cohesive user group, drawn from the DOE technical community,

would be chosen and involved from the start. This group currently numbers

about 30 materials data users associated with design and analysis work at

at Lawrence Livermore National Laboratory, Los Alamos National Laboratory,

and Sandia National Laboratories. In the Fall of 1984, the needs of this

user group were surveyed by questionnaire, [Appendix A], focus group

discussions, and personal interviews.

2. Initial implementation of a computer-based "alpha" prototype system,

including:

a. Data on a limited number of alloys taken from a single printed

data source, Aerospace Structural Metals Handbook (ASMH).

b. The data schema would include the majority of

mechanical properties included in ASMH but initially, only a representative set of tables and graphs would be entered.

c. Data entry procedures for both tabular and graphical

data would be developed and made available to other Federal

Agencies (e.g., NASA).

d. Access paths for the data system usage would be defined

and two or three examples would be implemented.

e. The SPIRES database system and its associated PRISM

software would be used.

f. The IBM PC family would be the only terminal supported.

g. A review of Stage I accomplishments, and the plans for

Stage II would be held for the user group in February 1986.

3. Revision and extension of the Initial Prototype to include:

a. Data on "150 alloys taken from two handbooks - MIL-HDBK-5

Aerospace Structural Metals Handbook

entered into databases and loaded in the system as distinct

databases.

b. Other data loaded from existing machine-readable sources,

as available (e.g., EPRI Pressure Vessel Steels Data, in

cooperation with the MPD Network).

c. A full user interface would be developed covering all defined

access paths.

d. The FORMS software associated with SPIRES would be utilized.

e. Data from the JANAF thermodynamical tables would

be added. (Optional)

6
f. (Hopeful) Easy graphical display capabilities would be

available, possibly as software on the PC.

g. The user community would be extended, possibly to 60

participants.

h. Database schema would be made available to standards groups

(e.g., ASTM) and to other database builders (i.e., NMPDN,

American Welding Institute, ACS)

i. The capability will have the user community contribute to

a "living" database consisting of recent test results.

(Optional

)

j. Another user meeting would be held in late 1986 or early 1987

to review status and progress.

IV. DETAILED CONTENTS OF THE INITIAL MIST PROTOTYPE SYSTEM

A. IMPLEMENTATION PHASES

As with every project of this complexity, it is important to have a

well-defined plan and schedule. For computer projects this is even more

critical. The MIST project has been divided into six phases, each addressing

issues of increasing difficulty and complexity.

III Mult Mult 1 1 Combined

Ilia Mult Mult Pass thru 1 Simple Gateway

IV Mult Mult Mult 1 V Mult Mult Mult Mult Enhanced Gateway

VI Mult Mult Mult Mult Mult Full Gateway

During the first phase, the emphasis was on determining what information

was needed and how it could be configured to impact user productivity

(essentially, an intense market survey plus database schema development).

The initial focus was on developing flexible and extensible data structures

which could facilitate storage, retrieval, display and downloading of data

for a representative set of selected materials from one printed data source,

along with revisions and comments on data extracted from that source.

A schematic representation of this simple initial architecture is shown in

figure 1 .

In the second phase, data from additional sources will be digitized

and incorporated into the system. While these subsets will utilize essentially

the same data structures as phase I, data files from those sources will be

logically separate.

Phases I and II only go part of the way toward building the core

system which can be used as the basis of a fully operational system. Other

work would include:

1 . East database loading capability

2. Establishment of multiple computer sites

a. First, using the SPIRES system

b. Second, adding communications capability to link one

or more DBMS on remote computers

8
3. Enhanced graphical display capabilities

H. Linkage to a statistical package for data analysis and

presentation

5. Portability of SPIRES by release of a C language PC version which

will allow distribution of database capability between a gateway

and a PC, as well as other mainframes

6. Additional databases covering more materials and properties

7. Extension of metadata and designation systems to nonmetallic

materials

Some of this work will naturally be supported by those groups who

plan to offer on-line services. It is imagined that this project will also

continue to attack these problems as resources permit.

In phase three, additional data sources will be added, some of which,

because of their different subject coverage, will require substantially

modified data structures. At this point, it is envisioned that the MIST

system will still reside at a single site on a single type of mainframe, and

use one type of database management system to connect logically distinct

materials databases. A possible extension of this third phase may be to

develop a simple gateway or "pass through" capability that will provide users

with a catalog of other accessible databases and perhaps assist in making

connections to other systems.

The fourth phase will emphasize development of a gateway capability

to link databases residing at multiple sites but running on the same DBMS on

similar hardware and operating systems. The goal at this stage will be a

distributed but homogeneous MIST system with remote databases and metadata.

A schematic representation of phase four is shown in figure 2.

The distributed architecture of MIST (Year 2 + ) will have

database and gateway nodes distributed across the DOE Complex.

The fifth phase will extend MIST to different distributed sites running

different types of hardware and operating systems, but still relying on a single data management system to provide uniformity over the diverse sites.

In the sixth and final phase, the ultimate goal is to provide multiple

gateways linked to different databases built on different types of database

management systems and residing on different hardware and operating systems.

As figure 3 shows, this phase will involve much greater complexity because of

the need to provide translation and mapping facilities for (1) metadata

maintenance, (2) query translation and decomposition, (3) different types of

systems interactions, (4) merging of heterogeneous output formats and

(5) different types of networks.

Because work is going on in other forums related to items on the right hand

side of Table 2, especially computer networking and DBMS-^DBMS interfaces,

the MIST project anticipates utilizing capabilities generated by others when

the later phases are started.

Phases I and II

The result of phase I was demonstrated at a set of user meetings held

in February 1986, and Stage II is scheduled for completion in late 1986 or

early 1987. However, recognizing the ambitious nature of the work required,

progress on this project is highly dependent on the availability of adequate

funding. Consequently, even within this schedule, the completion dates or

even the work itself may change because of circumstances beyond the

participants' control.

11
B. PHASE I

1 ) General Strategy

Phase I of the Prototype System includes data on a small set of alloys

from a single source, Aerospace Structural Metals Handbook (ASMH). The

materials are popular alloys for which there is considerable coverage

in at least two of the three principal source handbooks (ASMH, SAH,

and MIL HDBK-5). (See Appendix B). Consideration of the characterise

tics of the particular alloys defined the pertinent application areas,

which in turn generated the lists of required properties. (Appendix C).

Initial emphasis was on including those properties which could be

represented quantitatively and hence rigorously compared. However, the

database structure being developed will also accommodate qualitative

descriptions and comparisons of nonnumeric values of properties, where

appropriate.

Taken together, the initial alloys-^properties matrix was chosen

so as to:

a) serve as a test-bed for the general database schema

b) permit exercise of the Phase I prototype by the user group

with meaningful comparison and other manipulation procedures.

2) Scope of Materials and Properties

a) Materials

The initial materials group consisted of a set of 5 alloys chosen by

consensus based on input from the user group, the technical officer, and

the contractors. Each material selected has been identified by its UNS

number as well as by common names, trade association designations, etc.

The common names of chosen materials are:

304

316

43M0

17^PH

A356

A listing of Designation Cross Reference Data for these materials is

given in Appendix D.

12
b) Application Areas

The initial application areas, with associated required properties,

were confined to those pertinent to structural and heat transfer

applications. Extension beyond those application areas is contemplated

for later stages of the project. The user-'-identif ied application

areas are listed in Appendix E.

c) Properties

The properties to be included for each alloy numbered initially no

more than 60 individual parameters determined as described above. The

chosen properties are listed in Appendix F. No attempt was made

at this stage to record electronically all information found in the

chosen source handbook (ASMH). Rather, only data for the required

properties on the property list were captured insofar as possible.

Generation of a cumulative existence table for the materials-properties-*

sources, including notations of any omissions, was an important

requirement.

Existence matrices that identify for which materials specific property

data exist in ASMH are listed in Appendix G for the different

materials.

3) Auxiliary Information

a) Independent Variables

A particular problem was the decision as to which of the many effects

of independent variables on a sought property would be captured for

the Phase I system. Realizing that the initial objective was to exer-*

cise the database structure and expose the user group to some of the

system's functionalities, the initial data set was restricted to be

broadly representative and as a result did not include all data pro-*

vided in ASMH for all selected properties and all independent

variables. A current list of included independent variables is given

in Appendix H.

b) Potential Constraining Properties

An additional feature in MIST beyond just the data from ASMH is

that special attention is drawn to any property or properties of a

material which constitute(s) a possible limitation to certain applications of that material, either from behavior or from restricted avail-*

ability. This parameter has been termed in MIST "potential constraining

properties." As indicated above, these may or may not be application-*

specific. The existence of these types of data for a material can

be highlighted during data display and presentation.

13
c) Data Qualifiers

Data values to be incorporated from the reference source may be

qualified by the following elements:

revision date - date of last entry/update

value type - typical, max, min, etc.

capture method - keyed, digitized from graphical image, etc.

reliability code preferred or blank,

data quality indicator * limited use, qualified, highly

qualified (also total data quality "score card").

Specifics for some of these guidelines will not be completed during

Phases I and II of the prototype, but the database schema will accom-*

modate subsequent incremental additions and extensions.

A more complete discussion of data quality indicators and their

treatment in MIST is covered in Section X.

d) Glossary and Thesaurus

A list of all the unique terms for materials, properties, units, and

other descriptors was generated for all data added to MIST. For all

these terms, referenced definitions were compiled, allowable units

and conversion factors specified, and synonyms, abbreviations, and

symbols listed. The terms of this thesaurus/glossary serve as controls

for validating terms and units during data entry and searching for MIST

databases as well as a reference source for MIST users.

4) Information Organization

A database schema was designed to accommodate essentially all the

features necessary for entering data for the 5 alloys from ASMH in a

way that could easily be extended to an unlimited set of additional

materials, properties, and independent variables. This included notes,

cross-references, various data formats, etc. For further details, see

Section VI below on MIST System Architecture.

. PHASE II

1 ) General Strategy

The principal elements of the strategy for the second phase of the

MIST project will be to develop a full user interface; to enlarge the

content and scope of the database; to include data from data sources

other than ASMH; to extend coverage to a more diverse array of mate-*

rials and properties; and to expand the manipulation capabilities

offered the user.

14
The following goals are proposed for Phase II:

o A well-developed user interface with good data manipulation and

display functions

o A revised version of the data schema capable of supporting multiple

databases

o Multiple data sources including at least two printed and one

machine-readable

2) User Interface

First and foremost, an attractive, easy-to-use interface must be

developed that reflects the needs of the materials community.

This includes a fully-'-developed navigation through the system, complete

definition of all screens and their implementation, and system help

aids, all taking advantage of the power of the IBM PC, XT, or AT. The

goal is simple: to seduce the potential users, to have them say "That's

exactly what I want." Since statistical manipulation, report

generation, and especially graphical display are so important, these

must be included, either at the workstation or on the mainframe as

best practicable.

3) Data Schema

The data schema for mechanical properties must be finalized as much

as possible so that data entry rules and manuals can be widely

distributed. This recognizes that some changes need to be made

because of existing computerized files. These changes need to be

identified and made as close as possible to the beginning of Phase II

so that data loading may go forward routinely.

M) Data Loading

It is important to get enough data into the system so that users will

find it advantageous to turn to the system because they know they will

find useful information and so that the data schema and structures can

be fully exercised. Because resources are limited, actual data entry

will be separated in Phase II of this project from other work. In

addition, the data entry manual presently in draft form must be com-1 pleted.

However, loading of the databases into the SPIRES system will be an

important part, especially development of procedures to make such

loading as smooth and efficient as possible. It is hoped that data from

two printed sources and one or two existing machine^readable sources

can be loaded. Additional existing machine-readable sources may also

be added. These sources include:

15
Printed

o MIL-HDBK-5 (NBS)

o Aerospace Structural Metals Handbook (NBS)

Computerized

o EPRI Database on Pressure Vessel Steels (MPD Network)

o Strain-hardening Database (DOE)

The groups in parentheses will be responsible for providing the final

machine-readable copy to be loaded into the system.

5) Scope of Materials and Properties

The initial materials list will be extended to a wider range of

alloys, chosen so as to expose new application areas and new properties. The current list includes 172 selected alloys. Appendices I and

J indicate the existence of source data for those particular alloys

in the identified printed sources.

Extension of the properties coverage will be governed by the require-*

ments of new materials, application areas, additional data sources,

and recognition of user group requests. Modest extension of the effects of independent variables will be made, primarily to test fur-*

ther the functionality of the data structure architecture at this

stage of development.

Provision will also be considered for calculating derived properties

from basic data by stored algorithms. If possible, one example will be

provided for Phase II. Appendix K lists the derived properties to be

considered for inclusion.

6) Metadata Considerations

Expansion of the list of metadata elements, definitions, abbreviations,

symbols, etc. will be required because of the extension of coverage to

additional materials and properties. Increasingly, it will be desir-*

able to develop and present hierarchical structures covering the

various families of metadata elements and reflecting the different

data organization of the various data sources.

7) SPIRES Enhancements

Assuming that the PRISM full-screen menu development software is now

released, the primary needs for enhancements to SPIRES are related to

development of a C language version and to an easy-to-use interface

to graphics software. The C language version is necessary for com-*

patible database management on VAX's and IBM PC's. While completion

of this version to be done by Stanford is scheduled for 1987, it is

important to progress as quickly as possible.

16
Graphical display of materials data is so fundamental to its use that

good graphics is mandatory for acceptance of any system. This will

be addressed in work on the User Interface, but it may be necessary to

improve SPIRES capability to interface with graphics packages. This

work has to be completed in Phase II.

8) Information Organization

It is recognized that, as soon as possible, the system should provide

the capability for users to input their own data into the system for

manipulation and comparison purposes. If resources permit, this will

be done in Phase II.

9) Manuals

Two manuals, one for users and the other for data entry, will be

produced.

17
PROJECT ELEMENTS

a variety of sources, including:

o National Bureau of Standards - Office of Standard Reference Data

o Dept. of Energy - Office of Scientific and Technical Information

(OSTI)

o NASA - Marshall Space Flight Center

o U.S. Army - AML LABCOM

o Lawrence Livermore National Laboratory (LLNL)

Major Phase I work has been done, under grants from NBS, OSTI, and

Sandia, by three groups:

o Lawrence Berkeley Laboratory, Computer Science Research Dept.

o Sci-Tech Knowledge Systems, Inc. - Scotia, NY (KSI)

o Battelle Columbus Division - Columbus, OH (BCD)

Additional work for Phase I has been done under grants from NBS by:

o Stanford University, Information Technology Services

-Palo Alto, CA (ITS)

o Aaron Marcus and Associates, - Berkeley, CA (AMA)

B. Data Sources

To avoid problems of ending up with a system which contains data

of dubious quality, it was decided that two high-quality databases

would be built from existing high-quality handbooks, Military Handbook 5

(MIL-HDBK-5) and the Aerospace Structural Metals Handbook (ASMH).

Initially the databases would be created as separate entities so that

problems involving linking separate databases could be addressed, even

though the data drawn from the different sources would be stored in similar

formats on the same machine.

18
C. Categories of Users and their Requirements

The users of a materials database can be divided into several groupings

according to functional activities, engineering discipline, or applications. Questionnaires from the initial DOE user group yielded the

following background data on the types of activity. (The groupings have

also been identified from other user surveys of a more general nature):

1 . Functional Activities

- Engineering Design

- Materials Selection

- Engineering Analysis

- Quality Control

- Purchasing

- Maintenance/Service

- Data Analysis

2. Disciplines

- Mechanical Engineering

- Materials Engineering

- Electrical Engineering

- Chemical Engineering

- Nuclear Engineering

3. Specific Applications Involving Materials Data

(Ranked by relative user interest)

Stress Analysis

Thermal Analysis

Solid Modelling

Material Selection

Fatigue Analysis

Material Specification Development

Part/Subcomponent Design

Component Design

System/Multicomponent Design

Others:

(Identified by individuals)

Tool Design

Mechanical Testing

Material Testing

Reliability Analysis

Maintenance Analysis

Data Analysis

19
Some users may require capabilities for one or another of these purposes exclusively, while others will wish at times to use a mix of

them. The system will be structured so as ultimately to serve all of

these purposes, but with minimal capabilities initially. However, it

will be noted that the wide range of user activities implies many different motivations for accessing the database, and it needs to be recog-^

nized that the many different user backgrounds and needs may require

different or alternative forms of screen presentation and content, but

preferably with standard formats.

D. The User Group

A rapidly increasing amount of the technical work in DOE Laboratories is being performed by scientists and engineers using computers.

Selected staff members and first-level supervisors at Los Alamos Na-^

tional Laboratory (LANL), Lawrence Livermore Laboratory (LLNL), and

Sandia National Laboratories (SNL) constitute the initial user group

and have helped define and develop the MIST database system. Members of

the initial user group use computers in their daily work and represent

diverse organizations that need information on materials properties to

solve their problems.

Because of their previous experience with computers, the user group was

enthusiastic about the prospects for the project and felt their produce

tivity would indeed increase if a "corporate information system" for

DOE could be established. However, in spite of their frequent use of

computers, most users did not consider themselves to be computer scien-1 tists and, in general, they did not want to have to learn more about a computer system than necessary to solve their problems. As a conse-^

quence, because the users come from diverse backgrounds, a minimum of

technical jargon should be included in the system, and HELP fields

should be readily available to clarify technical terms and definitions.

E. Computing Facilities

Phase I work is being performed on computers at Lawrence Berkeley

Laboratory, Stanford University Information Technology Services,

Sci-Tech Knowledge Systems Inc., and Battelle Columbus Division.

Communications are being conducted through ARPANET, and also are

possible through Telenet and Tymnet, as well as by direct dial-in.

20
MIST PROTOTYPE SYSTEM ARCHITECTURE

This section briefly describes the software, hardware, and network

communications on which the current MIST prototype is being built. It

also outlines how various types of information are organized in the

initial MIST project.

SPIRES DBMS

The initial MIST project is being implemented on SPIRES, a generalpurpose database management system developed and supported by Stanford

University. SPIRES was chosen because of its unique combination of

capabilities for textual as well as numeric data, its proven ability to

handle large numbers of simultaneous users and transactions, its flexi^

bility and extensibility, and its history of support for innovative

applications. SPIRES is a mature fourth-generation system with full

data management capabilities, including schema definition and control,

report generation, design of full-screen forms, on-"line documentation,

interactive exec language, comprehensive security mechanisms down to the

individual element value level, data integrity and recovery, and an

extensive library of standard processing procedures for input validation, encoding, automatic indexing, query translation, and output

formatting.

SPIRES runs at over thirty installations outside Stanford. Member

organizations help provide support and development direction through the

SPIRES Consortium, which includes universities such as Harvard,

Princeton, and Michigan, as well as several federal organizations such

as the NASA Goddard Spaceflight Center and the U.S. Information Agency.

Hardware and Network Communications

The primary MIST prototype project is running on an IBM 308M under STS at

the Stanford University's Information Technology Services (ITS).

Another developmental version of the system is running on an IBM 3082

under VM/CMS at the University of California, Berkeley. Users can

access the Stanford system via ARPANET, TELENET, and TYMNET, as well as

via commercial telephone lines. For fastest response time and use of

the full screen PRISM interface, direct connection using a 2400 baud

modem with the MNP error-correcting protocol over standard telephone

lines gives the best results--though slower speed connections and a

line-^oriented interface are also available. Users can invoke one of

several electronic mail interfaces to send mail to anyone accessible via

ARPANET, BITNET, or other networks accessible from those.

21
Major Data Entities

Engineering and scientific information currently included in MIST can be

classified into seven broad types of entities: (1) Databases,

(2) Exhibits, (3) Data, (4) Terms, (5) Citations, (6) People, and

(7) Software.

Databases refer to the database sources incorporated, currently a single one (ASMH), but anticipated to be extended to multiple sources in

the future.

Exhibits are source tables, figures, paragraphs, and datasets from

printed publications and/or experiments from which the data were

obtained.

Data refer to a canonical representation of data extracted from these

different types of exhibits. Each data record pertains to a single

set of properties for a single material or a set of materials, sharing a common set of independent variables within the context of a single

exhibit.

MIST Terms is a central thesaurus and glossary for resolving the

multiplicity of names, definitions, etc., of materials science and

engineering.

It includes definitions for words, phrases, or symbols associated with

all materials, properties, independent variables, specifications,

measurement units, test methods, organizations, etc., included in the

database.

Citations are bibliographic information on source articles, reports,

references, etc., which may be linked to specific datasets, exhibits,

databases, terms, people, software, and other citations.

People includes information such as telephone numbers, electronic mail

addresses, etc., for experts, data reviewers, users, and SIRP Task Group

members.

Software includes selected application and manipulation computer

programs, subroutines, etc., which may be of use to material scientists

and engineers. This file will facilitate the contribution of software

from individual users as well as access to the latest version of such

software and associated documentation by other users.

22
Linkages and Relationships between Entities

The MIST project provides extensive linkages between different types of

entities during input, user searches, and output display. For example,

names of databases, materials, properties, and measurement units are all

automatically verified against the MIST thesaurus as a part of standard

data entry procedures. All basic descriptive information about a par-^

ticular material or property contained in the thesaurus is automatically

available to users at search or output time as well. When the name of a

person is included as part of a data record, users can automatically

access additional information (e.g., electronic mail address, telephone

number, etc.) from the "person" record corresponding to that same name.

Since related types of entities and databases contain comparable key

fields (as enforced by the thesaurus of names, terms, etc.), users can

make ad hoc connections between different types of data as the need

arises

.

Data Elements (Field Characteristics)

Information about each entity instance (data record for that type of

entity) is contained in discrete data elements (data fields) within

MIST. Some data elements are mandatory (e.g., last name for a person

record), while others are optional (e.g., name of one or more experts

associated with a particular database record). Even graphs are broken

down into over thirty distinct types of information components (e.g.,

scale type, variable, measurement units, caption, etc., for each axis,

plus symbol, caption, footnotes, etc., for each curve or set of data

points) as well as the numeric X-Y points themselves. Breaking down

such information into small discrete parts facilitates data entry

validation, indexing, searching, and flexible output display. SPIRES

permits addition of new data elements to the database definition for

each type of entity, so new types of information can be added as

necessary and the types of information for any given entity can evolve

gradually without having to reload entire databases when changes are

made

.

For each data element, MIST also contains additional metadata describing

automatic input validation checking procedures, index processing proce-^

dures, default output format specifications, storage requirements, data

type, short label for standard reports, full description for user help

and documentation, etc. All of this metadata is systematically organized within SPIRES file definition records, which are themselves

searchable, updatable, etc., by authorized project staff using the same

mechanisms for searching, updating, and display as for standard data

records.

Detailed information for every data element in every type of entity in

MIST is summarized in the appendix and will be documented further in the

Data Entry Manual scheduled for the end of Phase II.

23
VII. IMPACT OF THE MIST PROJECT ON USERS

The MIST Demonstration Project is a natural result of the pressures of

contemporary technology which compel consideration of the benefits of

computerizing well-used, frequently updated, scientific data sets.

Computerization, however, requires more than the translation of data

from a printed medium into an electronic medium. Some of the

impacts often associated with computerization in general, and which

seem to be important for MIST, are:

o Users may have higher expectations from computerized data systems

than from printed data compilations.

o Computerized data systems allow users more flexibility to review and

compare data.

One of the advantages of the use of computers is that in

computerized information systems, data can be collected and then

recombined in many different ways under user control. In any

printed handbook the available data are often presented in the

limited context of a well-packed page. This is particularly the

case with respect to data values embedded in text, tables, and

graphs. In MIST, information will be disaggregated in the sense

that individual pieces of information or data about a subject

of interest can be displayed on a terminal screen in isolation.

However, the capability will also exist for the user to display

the data in a different context, such as the format that ap^

peared in the original source (e.g., a graph, table, or para-*

graph) or one in which comparable data for several materials can

be viewed simultaneously on a single display. The wide variety

of MIST output options, both CRT and printed, will cause many

users to become more conscious of what they are viewing and, in

some instances, to be more critical of problems which they detect

in the data themselves and in the way the data are presented.

o The need for a local interface

The increasing availability of computer-aided facilities within

the nation's laboratories and manufacturing components to support

engineering, manufacturing, and purchasing leads to the expecta-*

tion that MIST will directly interface certain local computerized

functions and systems at the individual user level. When com-1' pleted, MIST should be able to support local computerized appli-*

cations, functions, and systems with comprehensive machine-"

readable databases, which in turn will enhance their further

utility for computer-aided engineering, manufacturing, and purchasing.

24
The availability of on-line computer HELP messages invariably

results in the opportunity to perform these tasks with

increased precision and effectiveness. This in turn places

requirements on the accuracy and completeness of the data

being supplied.

o The need for a comprehensive, consistent, and versatile data structure

The diversity of data presentation formats in the printed data

sources also affects the ease with which data from different

sources can be combined within one computerized information

system. Great attention is being paid in the MIST development to

ensure that the system includes accurate and consistent data

organizing procedures so that similar data from separate sources

are linkable within the system but dissimilar data are maintained

separate.

25
VIII. REPORTING

The following reports are scheduled to be completed:

Phase I

Project Overview - Phase I Report and Phase II Plans

Phase II

User Manual

Data Entry Manual

Project Overview - Phase II Report and Phase III Plans

A description of these follows.

Project Overview

This document provides a portrait of the MIST system which is

independent of specific choices of hardware, software, and system

architecture. This portrait is developed, to the maximum extent

feasible, in non-data-processing terminology and concepts so that

it can be fully comprehensible to the intended users/customers of

MIST. Its principal contents are:

o A fully shared understanding on the parts of the MIST

users/customers and the designers/developers regarding

the capabilities of MIST at the various phases of system

development

.

o A basis for the preparation of detailed design specifications

for each major phase of the development of MIST.

o A basis for the communication of functional specification

changes resulting from:

- Newly formulated requirements

- Newly available technological opportunities

- Increased understanding of the implications of

design decisions

- Redefinition of opportunities and constraints based

on resources.

o A basis for the user/customer to perform acceptance testing

of each phase of the development of MIST.

26
User Manual

A guide to users for using the MIST system that will include

explanations of all features of the MIST database and the various

user-controllable capabilities available to users, including types

of searches and options for output display.

Data Entry Manual

This manual will document the structures and procedures to capture

data from the various data sources, whether the source of the data be

from paragraphs, tables, or graphs. In particular, the procedures must

recognize the interrelation of the various record types in preparing

complete and consistent data records. The data record structures will

be useful in building mechanical property databases consistent with

the MIST system. In addition, the data record structure can be used to

capture all information relevant to mechanical properties regardless

of which database system will be used.

27
IX. EVALUATION, TESTING, AND FEEDBACK

A project this broad in scope requires evaluation and testing activities

for each phase if the system is to develop to fulfill user needs.

The following program of evaluation, testing, and feedback is planned:

1) A set of user-coordinators will be identified at each user site,

whose function will be to provide close user support as well as

guidance to the SIRP Task Group, especially in the early stages.

These users will receive extra training to ensure their awareness

of the system's potential and functionalities and their capability

to coordinate the feedback from users at their site.

2) Users agree that a system log of user interactions will be taken

throughout the initial phases. This copy will provide

system designers with important feedback on how users are

interacting with the system.

3) A user evaluation screen will be available to users upon exiting from

each session for their input to identify the relative success of the

session and to collect comments for changes or improvements.

If possible, the capability for users to insert comments at any

point in a session without resulting in a session interruption

will be available.

4) Discussion sessions will be held with users and led by user

coordinators to pinpoint user reactions and proposals for system

extensions or alternative processing capabilities.

5) Users meetings will be held so that users can be fully

apprised of system changes and their reactions to new

or additional features.

28
PART B - General Considerations

X. PROJECTED USES OF THE MIST DATABASE

A. Survey and Focus Group Meetings

A detailed survey form was developed by the SIRP Task Group in conjunction

with the Berkeley Survey Research Center (SRC). The objective of the

survey was to identify the specific factual information needed by the

user group, important functional capabilities users want, and the kinds

of computer hardware and software they currently have. Members of the

SIRP Task Group and the SRC staff met with the user group in focus

discussion groups and completed the questionnaire in the Fall of 1984.

The focus group meetings allowed the SIRP Task Group to hear how DOE

staff members presently go about their problem-^solving processes. They

also allowed the users to discuss changes that could make them more

productive. At the meetings, the SIRP Task Group learned that currently poor access and inadequate sharing of technical information on a

timely basis were causing substantial delays and reducing the reliability

of analyses.

The users asked that the SIRP system be an enhanced communications

system that connected them to factual data which could be downloaded

to their terminals both for analysis as well as for use in other

software. Also the system should identify experts who could be contacted

directly concerning the data and users' needs. The group wanted multiple

access paths to the data to be available (for the expert and nonexpert)

with more menus presented to the non-experts to guide them to the appropriate data.

B. Approaches to Data Usage

Three approaches were requested by the users:

1 . Browsing through the data

2. Locating specific information for one or more specified materials

3. Locating materials that satisfy a given set of constraints

Initially, many users want to browse through the available data and try

out the functions of the system. This experience approach appears to

be a general learning mode for the users, initially increasing their

familiarity with the data and ultimately speeding up their use of the

system. To be effective, this approach requires substantial investments in a thesaurus, glossary, and HELP files. An electronic mail

communications path back to the system manager or an individual expert

responsible for a particular data subset is important to allow the

browser to easily provide timely comments.

29
Users indicated that they often need to locate specific data,

compare values, analyze trends, etc.. They identified needs for

graphical and statistical plotting routines, and they want to be able

to download data to their terminals for use in other software analysis

and applications programs. They want a system that almost always finds

data being sought. This means there must be clear identification

of the data being maintained in the system, and as soon as possible,

the quantity and breadth of data in MIST should be increased to cover

most of DOE activities.

When users seek specific data, they usually have immediate applica-*

tions requiring analysis or decision making, and are not patient in

waiting for the data to be acquired by conventional library approaches.

Increased speed in getting access to data values is one of the principal

attractions of a computerized data system* This need for speed in lo-^

eating data in a computer-based system means that careful attention must

be given to search paths. Eventually, adaptive search paths may be

associated with particular users to help speed the retrieval of data.

Typically, users are seeking numeric data, that is, quantitative inform

mation. However, they recognize that associated qualitative descriptions

are also necessary in order to assure that the data being supplied are

appropriate to the problem.

C. The User Workstation

Members of the user group had access to IBM PC/XT/AT computer termi-*-

nals, and therefore initially those are the de facto standard terminals

being supported by the MIST system. The breadth of scientific informal

tion that users need suggests a software capability resident on their

terminals that would result in a flexible workstation environment. The

workstation, at a minimum, would provide a multitasking environment that

could:

1 ) Incorporate a communications package that would

connect the terminal to the MIST gateway,

2) Provide an initial menu set to allow easy interaction

with the MIST mainframe computer,

3) Allow appropriate functional software associated with

a particular database to be downloaded to the terminal

for more rapid off-line transfer and processing of

the data (ie. menus specific to the database, graphics,

statistical analysis, common theoretical analyses),

4) Permit easy data format control when the data are to be

used in conjunction with other application^type software.

30
D. Data Quality Indicators

User group members strongly urged that the quality of data being

supplied to users should be explicitly indicated. Many have also

requested that measures of uncertainty associated with data values be

stated. After reviewing how engineers and scientists use the inform-*

ation they have now, it appears that the best approach may be to provide

a reasonably detailed "pedigree" for each dataset, along with a brief

summary quality indicator.

Such a pedigree can also serve as "score card" to guide subsequent

upgrading of selected data subsets.

At this stage of development of the MIST project, the SIRP Task Group is

working with other groups interested in data quality indicators to

establish a general set of guidelines to indicate different aspects of

data quality. The model that is emerging identifies three general levels

of data quality, each of which is characterized by several specific

criteria as described below. The three general levels of data quality

are:

Limited Use Data

Qualified Data

Highly Qualified Data

Discussions with users confirmed that a minimum "threshold" for data

quality should be met before data are allowed into the system. Data that

satisfy these entry criteria, but which could not meet the criteria

required for the next level of data quality, have been termed "Limited

Use Data".

At the opposite extreme, from the standpoint of maximum scientific and

engineering integrity, a much more stringent list of requirements were

proposed, all of which seemed essential for critical applications. Data

that satisfied these criteria could be termed "Highly Qualified Data".

It was recognized that for many typical applications, a smaller or more

relaxed set of criteria would be sufficient, and this level was termed

"Qualified Data". The definition for "Qualified Data" may be somewhat

arbitrary, so users will also have access to the detailed "scorecard", so

they can assess the adequacy of the data for their specific applications.

E. Recommended Quality Indicators for Data in MIST

Users seem to generally support the data quality concepts developed by the

Department of Defense MIL-^HDBK-5 Coordination Committee, so data quality

criteria proposed for the MIST project follow many of the existing quality

indicator standards of that Committee. Quality standards from existing

reference sources will be "grandfathered" into the MIST project.

31
Within each general level of data quality, specific data quality

standards currently proposed for the MIST project are as follows:

A. Limited Use Data:

1. Data are traceable to an individual, organization, or

reference (both the data "Source" and "Digitizer" are

identified)

2. After independent review, an identifiable authority approved

the digitized version for inclusion in the database.

3. Basis of the data is identified

a. experimental measurements,

b. derived data - specify theoretical basis and data,

c. estimated data

Type of data is indicated

a. original point values,

b. analyzed data,

i. standard fit - specify fit and data;

ii. fit unknown

B. Qualified Data:

5. Number of measurements & data sets stated.

6. Nominal confidence limits estimated (i.e., .90, .95, n).

7. Traceable materials specification assures reproducibility.

8. Testing methods are specified and conform to a standard.

9. Data are traceable to a testing/data generating

organization or individual.

C. Highly Qualified Data:

10. High confidence limits determined (i.e., .99, .95, n).

11. Perform minimum number of individual measurements (i.e., 100)

- from minimum number of sample lots (i.e., 10)

- from multiple suppliers (if appropriate).

12. Data determined for each variable (i.e., form, processing

condition, size, etc.) that significantly affects the

property.

32
13. Independent testing (other than the producer & preferably

by several testing labs) performed.

14. A second, independent evaluation (evaluator identified)

15. All features explainable.

16. Producer(s) identified.

To proceed to the next higher level, all of the criteria for the lower

level(s) must have been met or exceeded.

"Limited Use Data" will probably be the most common entry level for data.

Some data may never be able to achieve a higher data quality level because

the material involved is inherently variable in its characteristics.

Because of the particular data sources chosen for the MIST project,

little current data qualifies for the "High Quality Data" designation.

However, if users want a standard such as this for materials usable in

critical applications, then in time appropriate data will no doubt become

available to the system. Since it will be possible to include data quality

designations grandfathered in by previous reference (i.e., "A Basis", "B

Basis", "S Basis", etc. of MIL-HDBK-5 )

, this is the appropriate time to

propose and implement a system of good technical criteria for future data.

The origin of the data maintained by the system is also important to

users so they apply only data appropriate to their problems. Thus, they

have asked that bibliographic citations relating to data be available

on request.

Whenever appropriate, preferred data sets will be indicated wherever

possible if there is more than one data set.

The detailed definitions of these data quality indicators are still

being developed. However, it appears that through the MIST project, a

significant improvement can be made in quality assurance and appropriate

audit trails established and maintained.

F. Data Integrity and Security Issues

Certain users of computer-based data compilations may need reassurance

that the values included in the database remain unchanged unless by

specific intervention and approval of those responsible for the integrity

and security of the data. This question of data value integrity is

closely tied to the security and integrity mechanisms provided by the

underlying operating system(s), database management system(s), and telecommunication system(s). Methods are being studied to assure that data

being sought and transmitted remain secure.

33
Related questions include:

who has access to the database?

who can add or change data values?

what audit trails exist to identify changes to values?

who have changed them and the reasons for such changes?

Other issues that the users expect will be part of the MIST

design and operation include:

Traceability of the data whenever it is accessed.

Definitions of terms, units, and properties.

Checks on the continuing correctness of the data in the database.

The current version of MIST provides full audit trails for input and

changes to each entity instance in the database, so that any subsequent

analysis of data values could reference a complete history of changes.

Data security issues are recognized as very important and are being

addressed separately.

G. Multisite Usage

Four DOE sites (LANL, LLNL, SNLA, SNLL) are participating in the

initial development of the MIST prototype. The users strongly endorsed

the concept of multisite access and usage of MIST because:

1. All users will have access to a single, common source of data

containing the "best" information

2. The information can be updated regularly, assuring all of the

DOE sites access to new data and minimizing duplication of data

generation, evaluation, and maintenance efforts

3. Through MIST, the materials experts will become more aware of DOE

needs and can focus their efforts on assuring that appropriately

qualified information is obtainable from the system

4. Data will be formatted in ways to support increased use of

CAD, CAE, CAM, and CIM

5. The system will provide a mechanism for increased communications

between people working on similar problems at different DOE

sites

.

34
H. Database of DOE Materials Experts

The need for the data system to provide a capability both to identify

experts and to provide fast communication with them has been included

in the design of the MIST project. In further discussions, the material

experts were enthusiastic about being identified as the local authorities on particular topics. They recognized that there is a growing

trend to bypass expert analysis and instead for users to simply use

digitized files existing on computers. Many of these experts are presently evaluating data, measuring properties, and consulting with project

leaders. They are very receptive to having a framework to share the

results of their work with a broader audience. This framework also

includes: 1 ) serving on expert panels which periodically would review

the data in their field of expertise, and 2) providing oversight to

assure that the data being accepted into the system are appropriately

qualified.

35
XI. DESIRED FUNCTIONAL CAPABILITIES OF THE MIST PROJECT

Below is given a description of the general functional capabilities that

have been identified by the user community and that would comprise a comprehensive MIST system. However, the initial phases of the system development

will, of course, not provide all these capabilities. The initial goals of

Phases I and II have been outlined in sections III and IV above.

A. Modes of Access to the Database

The principal modes of access required by users are shown in Figure 4.

The first mode is to obtain a description of some or all of the properties of a known material from the database. Another mode is to ascertain

a confirming document, such as a specification for a particular mate-*

rial, material-form, or material-form-application combination. Such a

requirement may serve a design engineer or a quality control engineer or

a purchasing agent; whereas a person performing an engineering analysis

is primarily interested in obtaining specific property values for previ-*

ously identified materials. A powerful and attractive access mode,

unique to the computer, is the ability to retrieve at one time, identifiers for all materials meeting a certain property profile, i.e., some

specified combination of properties, either quantitative or qualitative.

Other modes of access are also indicated in the Figure 4.

Access Modes for Users of Materials Databases

37
The initial screens used to introduce different types of users to

the system must therefore reflect the various types of access possible

and needed.

The easiest method available is to provide the user with logical branch^-

ing paths for the alternate search strategies, so that as a user reaches

a decision stage in the search, the alternatives presented provide an

unambiguous set of choices for search, display, or manipulation.

Support of Search and Retrieval (Query Scenarios)

) Menus or Commands

While in principle it is possible to have users learn a number of search

and display commands, in practice users are unwilling to spend much time

mastering the idiosyncrasies of any computerized system, at least until

they are convinced that the system is helpful and that they will use it

frequently.

In designing the first two phases of MIST, it has been assumed that

users will fall principally into two major divisions:

o Most users will prefer to take advantage of system-guided search,

retrieval, and output functions. For these, a front-^end access

system based on menus will be developed. The contents of the menus

will refresh the users' understanding of what the system can do for

them, and optional HELP screens will guide their search, retrieval,

and output preparation activities. Properly employed, these aids

will expose the user to information which usefully supplies and

complements the information that he/she is looking for.

o A smaller set of users consists of MIST developers or other fre-*

quent users, who will wish to exercise full logical access to the

database. For these individuals, the underlying DBMS (database

management system) query language (SPIRES), will provide the most

powerful and efficient access to the data.

Therefore, initially, search and displays-menus will be developed and

presented, suitable for new users, with the opportunity for the more

accomplished user to utilize "commands." Later, provision will be made

for a combination of both menus and commands for users who use the

system frequently.

38
The principal menus will cover:

i . Entry to the Database

ii. Options for Access Paths

Properties and Property Values

iii. Options for Manipulation (later)

Point Plotting

Curve Fitting

Graphic Overlay

Statistical Analysis

Capability to Plot Output

Capability to Plot User Supplied Data (later)

iv. Options for Display

Material Description

Comparison Tables

Bibliographic References

For those individuals using menus, different levels of assistance

will be needed.

o Some users will access MIST only very occasionally. Their approach

to MIST will continually resemble the approach taken by any naive

user who is starting out to use the system. Such users would probably rely on the front-'-end access system on each occasion of use,

with only a minimal amount of retained knowledge of the techniques

for accessing MIST. Such users will probably not expect to develop

the skill required to fully exploit some of the more complex logical

capabilities embodied in the system.

o Users who access MIST with greater frequency will be able, if they

wish, to make more effective use of the front-^end access system in

two respects:

- First, to obtain their information with a more streamlined

use of the front-end, not being delayed by explanatory

information which they no longer require.

39
- Second, to access logically sophisticated features of the

front-^end access system, that would be difficult for a naive or

infrequent user, but that become convenient features as individuals

acquire greater understanding and skill with respect to the MIST

database

.

b) Purposes for Searching, Manipulating, and Displaying Data

How data are to be used provides another way of looking at

access paths for MIST.

Results or data from the database may be intended for:

o incorporation into completely manual engineering design work

o incorporation into a terminal/PC-aided work activity

o downloading into a personal database either on a host or on a PC

o direct incorporation into a computerized engineering design

or application program on another computer.

Initial user input indicates that all these uses are contemplated,

with downloading assuming the greatest immediate importance. The

MIST system will be designed to eventually accommodate all of these

output requirements, with as full as possible implementation in

Phase II.

Search Capabilities

MIST will provide search and retrieval screens that make available to

the user some of the power of the underlying DBMS, particularly as it

relates to the needs for identifying candidate materials for an applica-"

tion for executing design engineering on a specified material, or for

determining material-based requirements to perform repairs or replace-1 ment of a structure involving an unfamiliar material. Selection of

candidate materials in terms of almost every category of data in the

database will be directed by use of the menu screens.

It is assumed that most normal search and retrieval strategies will

include such major data categories as:

o Quantitative Properties

o Qualitative Properties (including information such as machinability

,

processability , and application data)

o Subject term descriptors which describe the generic category of the

material involved (e.g., low alloy steel or aluminum casting alloy);

the form in which it is supplied (e.g., sheet or wire); the process

used (air melt or vacuum melt); etc.

Therefore, in Phase II, development will focus on the menu screens for

the most effective use of these and other elements in formulating and

searching for candidate materials.

40
This approach does not ignore the fact that other types of users, such

as purchasing agents and manufacturing engineers, will access information

about a material principally through use of a common name or designation

number. Such an access strategy can also be efficiently supported by the

search and retrieval menu screens.

a) Menu Search System

The menu search and retrieval screen system will support the user by

providing:

o An orderly sequence to a search that reflects specific search and

retrieval strategies (see next section)

o Easy access to a supporting thesaurus so users can obtain the

information they need to select appropriate search parameters such

as subject terms, property names, and quantitative property units.

o Supporting definitions and descriptions which enable the user to

frame the search in familiar terms and in familiar logical sequences.

o Optional access to supporting definitions, pertinent test methods,

etc., to clarify apparent inconsistences.

b) Specific Search and Retrieval Strategies

Three common uses of materials information will be supported by search

and retrieval strategies.

o System Browsing

Before specific property parameters are entered for a search, the

user can browse through lists of quantitative and qualitative properties, and units (of measurement). In the MIST project, values for

specific properties will be indexed uniformly in consistent units

though entered in the units of the original source. The user may

specify other units, in which case the system will convert, as

necessary, during the performance of the search, and retrieved data

will be presented in the units specified in the query.

o Materials with Specific Properties

The menus will enable the user to retrieve any stored information

which is linked to the materials related to the properties searched.

Knowledge of the underlying DBMS query language will not be necessary in order to formulate a search strategy using sophisticated

criteria.

41
o Properties of Specific Materials

The user either provides a material name or designation number(s) or

selects other access paths, such as combinations of descriptor terms

until the applicable UNS numbers of potential materials are deter-*

mined. The existence of values for specific properties of these

materials can then be ascertained by combining search parameters

(e.g., property names, quantitative property values, subjects,

titles, tradenames). Searches for a material's qualitative properties are possible by allowing the user to retrieve data by the

presence of keywords or text strings in various property fields.

Manipulation Capabilities

Examples of some of the manipulation capabilities which will be available

in MIST follow. However, not all (especially the latter two) will be

available initially.

o The existence of qualitative and quantitative properties data on

materials for selected independent variables can be retrieved and

compared in order to narrow a set of relevant property records. The

user would first identify the properties of interest together with

selected independent variables. The system then retrieves and displays the number of materials that satisfy those criteria. The user

may then introduce other properties, property values or independent

variables, or revise those previously supplied, to expand or contract

the list and display a comparison table.

o The user can perform quantitative property searches setting minimum, maximum, or nominal values for each of as many properties as

needed. If desired, those properties can also be searched with respect to minimum, maximum, and desired values of independent

variables which can be specified with or without specifying a value (s) for the property.

o The user can view the presence or absence of quantitative properties

for several materials at a time. The existence table that is dis-*

played indicates whether or not quantitative properties data are

available or derivable.

o Materials having derivable properties can also be compared, and the

property to be derived determined for several materials at a time. It

is not necessary for the user to provide the formula involved in the

derivation or to determine whether the properties used in the deriva-*

tion process are already known for the materials. Ultimately, the

user will be able to create his own derived property, such as a

f igure-of-merit , by defining the algebraic combination of standard

properties desired.

42
Having retrieved a specified set of values from the database, the user

may wish to:

o obtain rank-ordered lists of property values for different materials

o display combinations of data values in a comparison table

o download the data to his/her own PC or workstation for further

manipulation or incorporation in application programs. An

appropriate file transfer format will need to be adopted for this

purpose. Initially, the system should provide data output records

which correspond to the format of the input records from data

capture.

and in the future, have additional types of manipulation capability such as:

o a statistical package to analyze and characterize retrieved and user-*

supplied data sets

o a built-in graphics package to:

- apply different coordinate types and scales

- take tangents and intercepts at cursor-'specif ied locations

- interpolate or extrapolate from presented data according

to stored algorithms

E. Display Capabilities

a) CRT Display Output

o Display of qualitative and quantitative property data for one or

more selected materials will be in a table of contents or existence

table format.

o Capability to select further from previously selected materials to

appear in a display so that final outputs include only materials of

interest.

o Qualitative property data displays such that basic descriptive

data for each individual material will be displayed separately.

Quantitative property data will also be displayed for each

separate material or, where appropriate, will also be given in

tabular form showing material versus property value.

o Screens for inspection of properties, comparison of properties and

materials, and property derivations that prompt the user for entry of

his choice of the appropriate fields and values. Performance of an

inspection, comparison, or derivation may result in a multi-screen

display that can be browsed; any or all screens may be saved for later

printing. The user is also given the option of returning to previous

screens for further refinement of the search/analysis or to branch

to other activities.

43
o Graphical capabilities enabling the user to:

- display values of any quantitative property as a function

of one selected independent variable (2D plot) or two such

variables (3D plot) with arbitrarily chosen coordinate

types and scales.

- overlay up to four such 2D plots over one another, providing

all are members of the same family or involve a common independent variable.

- display domain or cluster plots of any values of two different

properties for a variety of materials.

- exercise various manipulations of the point sets on which the

graphical presentation is based.

b) Hard Copy Output

o The selection of materials and properties to be printed will be

the same as that of CRT displays.

o Hard copy output can be printed locally, if compatible printers

and/or plotters are available, or can be printed at a central site

for subsequent delivery.

F. Application Programs

The user will wish to have, either on other mainframes or nearby on his

own PC or workstation, various application programs to make engineering

use of the data from MIST. The format, data units, and completeness of

the database should be such as to permit direct operation of these programs

with little or no restructuring or introduction of information external to

the System. Such application programs include, for example:

finite element analysis

life prediction

failure rate projections

specific design calculations

As noted earlier, a File Transfer Format will need to be either established, or adapted from existing ones, such as IGES (Initial Graphic Exchange

Specification), so that users will be able to download results and data to

their own PCs or workstations.

G. Considerations for Entry of Private Data

The user is able to enter private data, following the System data structure, thereby using MIST as a type of electronic laboratory notebook. Once

the data have been entered, the user should be able to install software "locks" to ensure the privacy of personal files.

44
H. On-Line Helps

a) System Helps

All of the software components of MIST will be supported by the provision of on-line help information. This has proven to be a very flexible

way of providing readily accessible support for the user of a computer

system. It is immediately there when the user requests it, but does not

get in his way when it is not needed. An effective set of HELP messages

can in many instances eliminate the need for a user to consult either

written documentation or engage in oral communication with the MIST

staff in order to discover how to take the next step.

Knowing that effective HELP messages are available and easy to access

determine whether a computer system-shy user is willing to try the

system or will decline to make continuing use of it.

b) Intellectual Helps

One important type of intellectual "help" is a "definition" command that

can be invoked for each important term in the primary metadata list.

Another is an "example" command that would present a concise instance of

the usage of the term in question. For information systems of this

complexity, thesauri must be available and continually expanded to

provide equivalancy tables for both alternative material names and

numbers, as well as indications of hierarchical relations between terms.

It might also be noted that the availability of HELP commands and the

existence of a thesaurus also facilitate and provide validation during

data entry, particularly when data are being extracted or compiled from

diverse data sources.

I. Training

In order to be effective, MIST must be introduced to a large, diverse

and scattered community of users. Many of the intended users will have

had little experience or interest in using a computer-based information

system. Efficient, effective, widespread use of MIST will, to a large

measure, depend on how well it is introduced to the user community. A

well-planned and well-executed training program can make a major contribution to the success of this introduction. Training will ensure:

o That the users understand the benefits which accrue from MIST,

and that there are no economic or other penalties associated

with making effective use of MIST;

o That the users have a detailed understanding of the available

capabilities of MIST, where their access point(s) are located, and

how to log-on the system and get started;

45
o That the users have sufficient technical information so that they

can proceed to obtain from MIST those services which they

realistically can expect to receive, and

o That these perspectives can be provided to new engineers and

purchasing agents as they enter positions where MIST can provide

important informational support.

a) Direct User Training

It is assumed that the basic introduction to MIST and how to use it

will, to the maximum extent feasible, be provided in the form of

direct user training. Computer systems which are delivered without

adequate user training are often seriously underused for years following

their introduction, and may even be discarded as a consequence of the

lack of such support.

b) On-Line Tutorials

Although not a substitute for direct user training, there will be a role

for on-line, computer-aided instruction which can be made available for

system users. Such instructional programs can support users with:

o Introductions to modifications to MIST and expanded expositions of

its informational capabilities.

o Opportunities for users to increase their technical skills in the

uses of the System above those provided as part of the introductory

training.

46
XII. DATA CAPTURE

Data capture is the process of selecting and entering materials

property data into a Database. It involves a series of steps that consist

of: identifying the data to be entered; editing the original source data

and the associated information; keying the data into specific input formats; updating the database; and verifying that the data have been correctly entered.

The data capture steps described below pertain to material property data

contained in various scientific and engineering handbooks. However, for

the entering of existing computer files or user data into the MIST system,

comparable procedures still need to be developed.

A. STEP 1 . Data Selection and Identification

The criteria for the selection of the material and properties for the

prototype system have been given earlier. This process can be generalized

as follows:

a) Identifying and setting priorities for the materials to be

included, as well as the properties desired, based on the

pertinent application areas.

b) Identifying the property data available and their occurrence

in the various data sources.

c) Selecting the property data to be processed. This step involves

identifying from which source the data are to be obtained and

in what form they are presented, (i.e., table, paragraph, figure,

or graph)

.

d) Identifying the bibliograhic and secondary references from

which the data were originally obtained.

B. STEP 2. Source Editing and Data Transcription

Data editing is the process of preparing the data sources for input

into the MIST Database. The procedures involved are dependent on the type

of source being processed:

a) Paragraphs/References - paragraphs and reference data require

no editing, other than providing a copy of the data which has

been marked to identify the selected information.

b) Tables tables usually require no additional editing other than

providing a copy of the table. However, complex tables may require

special attention by an editor.

47
c) Figures/Graphs - figures and graphs require several types of

editing activities so that:

"the dependent and independent variables be correctly

identified for entry into the database

-the data from the plot be captured in digitized form

(using a sufficient number of points to define the graph),

either manually or semiautomatically , by the use of an

electronic tablet.

-all associated metadata needed for interpretation of

a graph or figure be identified. Some of these data may lie

outside the graph proper - in the caption, text, or elsewhere.

C. STEP 3. Data Entry

Data entry involves the keying of data into a predesigned input

format, dependent on the record type required for that type of data. A

complete discussion of the different record types and the data within them

will be included in the Data Entry Manual. The general procedures for

handling the different types of data are given below:

a) Paragraphs/References - the data for paragraphs and references

are extracted directly from the source provided.

b) Tables - tabular data require an understanding of the structure of

the individual tables and identifying the various independent and

dependent variables. The data must be inputted in a controlled

structure, so that the unique column and row structure is preserved

and a subsequent loading program can identify the individual data

tuples to be extracted and stored in the database.

c) Figures/Graphs - the treatment of figures and graphs is analogous to

that of tabular data except that the axis-based structure of the

figure or graph is captured rather than the column and row structure

of the table. The inputting of the digitized data from the electronic tablet is straightforward once the structure of the graph is

established.

In the MIST database, the data structure, formats, and order in

which the data are to be entered are very important, and special controls

must be exercised during this stage of data capture in order to ensure

correct order, exact data element names, and correct formats in the data

files.

48
D. STEP H. Data Validation

Data validation is performed on all data entered into the MIST

database, either during data entry, by testing the input against validation tables, or after data entry, by obtaining a presentation printout of

the inputted data in a format appropriate for the type of data being

validated, (i.e., table, graph, paragraph, etc.), and then comparing it

with the original data source. Checking for correctness of terms, etc.,

can be performed during data entry using built-in file definition and

thesaurus validation procedures within the system.

E. User-^Entered Data

In the future, users will be provided the option of entering their own

data, either to be directed into a private file for their own use or else

following some review and acceptance procedure into a central file for

general access. If the data are to be used privately, then the individual

user will be responsible for entering and maintaining the data. If the

data are to be directed for general use, then a central location will need

to be established to accept, process, and validate such data. In either

case, the steps outlined above must be further evaluated and procedures

developed to ensure the consistency and integrity of user-selected and

-'•entered data.

bibliography or literature survey, mention it here)

This report documents the initial phases of the MIST database, which is a demonstration project jointly supported by the Department of Energy and the National

Bureau of Standards „ The purpose of the Materials Information for Science and

Technology (MIST) is to demonstrate the power and utility of computer access to

materials property data. The initial goals include: to exercise the concept of

a computer network of materials databases and to build a demonstration of such a system in a way as to be suitable for use as the core of operational systems in the

future. Phases I and II are described in detail. In addition, a discussion is

given of the expected usage of the databases.

Technical Publications

Periodical

Journal of Research—The Journal of Research of the National Bureau of Standards reports NBS research

and development in those disciplines of the physical and engineering sciences in which the Bureau is active. These include physics, chemistry, engineering, mathematics, and computer sciences. Papers cover a broad

range of subjects, with major emphasis on measurement methodology and the basic technology underlying

standardization. Also included from time to time are survey articles on topics closely related to the Bureau's

technical and scientific programs. Issued six times a year.

Nonperiodicals

Monographs—Major contributions to the technical literature on various subjects related to the Bureau's scientific and technical activities. Handbooks—Recommended codes of engineering and industrial practice (including safety codes) developed in cooperation with interested industries, professional organizations, and regulatory bodies.

Special Publications—Include proceedings of conferences sponsored by NBS, NBS annual reports, and other

special publications appropriate to this grouping such as wall charts, pocket cards, and bibliographies.

Applied Mathematics Series—Mathematical tables, manuals, and studies of special interest to physicists,

engineers, chemists, biologists, mathematicians, computer programmers, and others engaged in scientific and

technical work.

National Standard Reference Data Series—Provides quantitative data on the physical and chemical properties

of materials, compiled from the world's literature and critically evaluated. Developed under a worldwide program coordinated by NBS under the authority of the National Standard Data Act (Public Law 90-396).

NOTE: The Journal of Physical and Chemical Reference Data (JPCRD) is published quarterly for NBS by

the American Chemical Society (ACS) and the American Institute of Physics (AIP). Subscriptions, reprints,

and supplements are available from ACS, 1155 Sixteenth St., NW, Washington, DC 20056.

Building Science Series—Disseminates technical information developed at the Bureau on building materials,

components, systems, and whole structures. The series presents research results, test methods, and perfor- mance criteria related to the structural and environmental functions and the durability and safety

characteristics of building elements and systems.

Technical Notes—Studies or reports which are complete in themselves but restrictive in their treatment of a

subject. Analogous to monographs but not so comprehensive in scope or definitive in treatment of the subject

area. Often serve as a vehicle for final reports of work performed at NBS under the sponsorship of other

government agencies.

Voluntary Product Standards—Developed under procedures published by the Department of Commerce in Part 10, Title 15, of the Code of Federal Regulations. The standards establish nationally recognized re- quirements for products, and provide all concerned interests with a basis for common understanding of the

characteristics of the products. NBS administers this program as a supplement to the activities of the private

sector standardizing organizations.

Consumer Information Series—Practical information, based on NBS research and experience, covering areas of interest to the consumer. Easily understandable language and illustrations provide useful background

knowledge for shopping in today's technological marketplace.

Order the above NBS publications from: Superintendent of Documents, Government Printing Office,

Washington, DC 20402.

Order the following NBS publications—FIPS and NBSIR 's—from the National Technical Information Service, Springfield, VA 22161.

Federal Information Processing Standards Publications (FIPS PUB)—Publications in this series collectivelj

constitute the Federal Information Processing Standards Register. The Register serves as the official source ol information in the Federal Government regarding standards issued by NBS pursuant to the Federal Property

and Administrative Services Act of 1949 as amended, Public Law 89-306 (79 Stat. 1 127), and as implemented

by Executive Order 1 1717 (38 FR 12315, dated May 11, 1973) and Part 6 of Title 15 CFR (Code of Federal

Regulations).
