DPC 2002 Retreat

Metadata Status Report

(2002 Sep. 4)


Metadata purpose

Metadata Purpose

Capture resource information in a structured format for discovery

Resources: websites, services annotations, collections, activities, images, news&opps, etc.

  • Services: Capabilities that enhance DLESE functions (e.g. OAI)

  • Annotations: Additional information about a resource that is provided by non-resource creators or users of the resource.

  • Collections: Resources grouped together because they are organized around a theme, organization or some criteria.


Five facets of metadata

Five Facets of Metadata

  • Framework Development: Develop XML structures for capturing resource information

  • Metadata Maintenance: Make structural or semantic changes records

  • Framework Documentation: Interpretation of the framework, vocabularies and cataloging best practices

  • Collection Management: Export or import records in appropriate formats

  • User Support: Tool instructions, cataloging support and collection building


1 framework development

1. Framework Development

  • NSDL: DLESE-IMS records  NSDL compliant

  • Collection-level: Describes a group of item-level metadata records as a whole

  • Item-level: Describes individual resources

  • New & Opportunities: Describes community conferences, workshops, grants, jobs etc.

  • Annotation: Review status of item-level records

  • Services: Describes available services


2 metadata maintenance

2. Metadata Maintenance

  • Addition or update of fields: (ESS vocab, standards, more geospatial coverage)

  • DLESE-IMS  ADN: dfsdf


3 framework documentation

3. Framework Documentation

  • Cataloging best practices: How to complete a field; 1 pt of chg, 6 pts of propagation.

  • Framework interpretations: The definition, occurrences & use of fields; 1 pt of chg & prop.

  • Vocabularies: Defintions; 2 pts of chg, 6 pts of propagation (e.g. NSES implementation)

    • Develop the vocabulary, its definitions and use:

      • 6-12 months or longer depending on the vocabulary.

      • not required here because used National Academy of Science.

    • Vocabulary in the metadata: Aug. 2001

    • Vocabulary in the DCS: March 2002

    • Vocabulary in the discovery system: To be determined


4 collection management

4. Collection Management

  • Incoming DCS collections:

    • Carleton, DWEL, Eval. Toolkit (100+ records)

      • Have DPC support in tool and record maintenance

      • In DLESE-IMS

  • Incoming non-DCS collections:

    • COMET, AVC, JDL, NAP, CRS, JESSE (9000+ records)

      • Not in current DLESE-IMS rather in Dublin Core or native

      • Have little or no DPC support

  • Outgoing collections:

    • DLESE-IMS, Simple Dublin Core, News & Opps, Qualified Dublin Core


5 user support

5. User Support

  • Cataloger Training/Support: Reached 185 people directly since Jan. 1, 2002

  • Collection Support: How to map COMET native metadata to DLESE-IMS?

  • Will change dramatically

    • Increase in cataloger training/support with more remote DCS users

    • Increase in collection builder questions about getting to the DLESE-IMS format


Issues policy questions

Issues: Policy questions

  • Metadata cannot do everything: e.g. including advertising info. is beyond item-level metadata.

  • Establish a framework development process: To create framework versions and a less haphazard method for adding fields & vocabs.

  • Establish a collection approval process: Explain the mechanics of the Collections Accession Policy process of becoming a collection.


Exposures priority resource limits

Exposures: Priority & Resource Limits

  • ESS vocabulary development: DPC participate

  • Alpha and beta testing: metadata not have

  • Metadata maintenance: shuts down the DCS for the transition to ADN and DCS code upgrades

  • Dramatic increase in collection support: For non-DCS collection builders to get correct metadata format; need framework docs

  • Need ADN now: To enforce required metadata & vocabs for non-DCS’ers; collaboration is slow.
