## CDL-T

- Technology
- CDL Technologies group no longer a organizational entity, programming resources are now mostly distributed to the program areas
- “Technical Leads” for program and service areas meet as the “Technology Council” and organize “all hands” meetings for technologists
- We should have a position posted soon for the Manager of Infrastructure and Application Support; responsible for technology purchases, managing data center relationships, and supervising system and database administrators.  See http://jobs.ucop.edu/

## 4 FTE
Responsible for certain CDL services
Online Archive of California
EAD encoded archival descriptions
Calisphere
OAC content matched with California curriculum standards
Counting California
Census and other data
UC Image Service
Collections for UC instructional use

## Digital artifacts and their description precede the METS
METS provides a tree structure to bind the files of the digital objects together, expressing the relationship between the files and metadata about the files
Supports arbitrary XML to encapsulate descriptive information
METS documents are not the objects, they are descriptions of the objects
Deference to curatorial discretion

## CDL Guidelines for Digital Objects

- The CDL Guidelines for Digital Objects  provides specifications for all *new *digital objects prepared by institutions for submission to CDL for access and preservation services. They are not intended to cover all of the administrative, operational, and technical issues surrounding the creation of digital object collections.
- They specify the use of METS, minimum descriptive metadata
- Specifies requirements for preservation and access “service levels”

## METS profiles describe classes of METS digital objects that share common characteristics, such as content file formats (e.g., digital images, TEI texts) or metadata encoding formats (e.g., MODS or Dublin Core). Profiles should include enough details to enable METS creators and programmers to create and process METS-encoded digital objects conforming with a particular profile. A METS profile itself is an XML document that must adhere to the METS XML Profile Schema. For information about METS profiles, see the METS website.
METS files must conform to valid METS profiles, which must be declared during pre-submission discussions with CDL staff.

## Content Contributors

- UC Campus libraries, archives, and museums
- Other public and private California universities
- Public and private California museums
- California historical societies
- California public libraries and library systems

## Historically CDL created METS
EAD Extraction; semi-automated production from submitted metadata and files
New projects use some sort of digital asset system with METS support *
GenDB (run by UC Berkeley Library)
CONTENTdm (run by califa) and 7train 
Anticipated future submissions
Archivists Toolkit
FileMaker based systems
* METS by hand from a recent library school graduate who read the CDL GDO

## For each profile of METS that is supported:
test ingest with voro and modify if needed
write an XSLT style sheet to extract a Dublin Core record
write an XSLT to display the objects

## eXtensible Text Framework

- _[http://xtf.sf.net](http://xtf.sf.net/)_
- Integration of Saxon and Lucene + other features
- Implements “lazy parse trees” which index the start and start of every XML element with a custom DOM.  Allows near instant creation of a DOM object without re-parsing very large XML files.
