**Finding a Common Demonimator:**** The Goddard Core Metadata Set**

## What Is Metadata?

- Data about data
- “Header information”
- Information that is currently entered or extracted for project documents
- Also common standards like those used in library catalogs: author, title, etc.

## Purpose

- Resource discovery
- Location of resources
- Organization of resources in collections
- Administration
- Technical reproducibility
- Other functions like preservation

- Goddard Library Visiting Committee

## Various Metadata Standards

- MARC – traditional library catalogs
- Federal Geographic Data Committee Content Standards – georeferenced data sets
- ONIX – elements, including pricing and cover, that is used in promoting books and magazines
- Encoded Archival Description – used in records management
- Dublin Core – limited set of elements to describe web-based resources

- Goddard Library Visiting Committee

## Metadata in Project Libraries

- Project libraries have metadata already
- Many core elements can be identified
- Each project library software tool has defined its own with more or less flexibility
- Difficult to interoperate or search across the libraries because of these differences

- Goddard Library Visiting Committee

## Benefits of Searching Across Collections

- Breaks down stovepipes
- Users don’t care where the information comes from and sometimes don’t care about format
- Aids in long term preservation and reuse when you no longer remember where it came from

## Digital Archiving System

- A prototype that shows searching across collections using a metadata repository
- Developed by GSFC Library based on initial research done under the Director’s Discretionary Funding
- Partnership with University of Maryland College of Information Studies and Code 588
- Provides cross object searching of videos, archived web pages, digital still images, animations and project documents

## Goddard Core Metadata Element Set

- Based on the ISO Standard for Descriptive Metadata (Dublin Core)
- Reflects GSFC’s project orientation
- Extends the Dublin Core set with important elements such as instrument, project name, project number, mission phase
- After initial set was developed tested against various materials including mappings to some project library sets
- Reduced set developed to make the task less onerous
- Some administrative elements also defined
- Currently, reconciling the Goddard Core with the Web Guidelines for metatags

## Metadata Review Group - Homepage

## Metadata Review Group

- Internal and external stakeholders and experts
- Includes people at Glenn and Jet Propulsion Laboratory who are also working on these issues
- Provides comments on the Goddard Core as it is developing
- Identifies opportunities for us to make others aware of this work
- Meets quarterly

- Goddard Library Visiting Committee

## How is the Goddard Core Used?

- Create metadata for archived Web sites of scientific and technical interest
- Create metadata for images in a database of scientific images and animations
- Applying it to videos
- Special Landsat History and Balloon Technologies projects

- Goddard Library Visiting Committee

## How Can Project Libraries Get Involved?

- Comment on the Goddard Core
- Join the Metadata Review Group
- Provide metadata for mapping to the Goddard Core
- Provide collections
