ASIS&T 2010 ASIS&T 2010 Presentation Transcript

  • Diane I. Hillmann
    Metadata Management Associates/Information Institute of Syracuse
    RDA Vocabulary Developments Based on FRBR
  • A brief history
    A structural tour, including:
    Rationale and decision making
    Use of domains and ranges to express FRBR structure
    Potential for extension
    Moving towards completion
    What we’ve learned
    Setting the Stage

  • Met at the British Library April 30/May 1, 2007
    The participants agreed that DCMI and the Joint Steering Committee for the Development of RDA should work together to:
    Develop an RDA Element Vocabulary
    Expose RDA Value Vocabularies
    Develop an RDA Application Profile, based on FRBR and FRAD
    The first two are largely complete; the third is started
    Still negotiating review process

  • Property and value vocabularies registered on the Open Metadata Registry (formerly the NSDL Registry): http://metadataregistry.org/rdabrowse.htm
    ‘FRBR in RDA’ Vocabulary declared as classes
    RDA Properties declared as a ‘generalized’ vocabulary, with no explicit relationship to FRBR entities
    Bounded subproperties for the generalized elements explicitly related to FRBR entities (using ‘domain’)

    • Some properties related to more than one FRBR entity
    • Relationships in Appendix J actually include the name of the FRBR entity in the name and have separate definitions (we re-used this strategy for the FRBR-bounded properties)
    • Other properties and sub-properties appear multiple times in the text and ERDs, with the same definitions and no indication that they might be repeated elsewhere (we consolidated these)

  • In 2005, the DC Usage Board worked with LC to build a formal representation of the MARC Relators so that these terms could be used with DC
    • These have been superseded by the ‘new’ id.loc.info version, without the relationships to DC terms (has been pushback on this decision!)
    • This work provided a template for the registration of the role terms in RDA (in Appendix I) and, by extension, the other RDA relationships
    • Role and relationship properties are registered at the same level as elements, rather than as attributes (as MARC does with relators, and RDA does in its XML)

  • The inclusion of generalized properties provides a path for extension of RDA into specialized library communities and non-library communities
    They may have a different notion of how FRBR ‘aggregates’, for example, a colorized version of a film may be viewed as a separate work
    They may not wish to use FRBR at all
    They may have additional properties to include, that have a relationship to the RDA properties

  • Completing the hierarchies, both generalized and FRBR-bounded
    Elements and Relationships need to have bounded hierarchies built (generalized hierarchies complete)
    Roles need generalized properties created
    JSC review incomplete, for both properties and vocabularies
    Status designations need to be updated from ‘New—proposed’ to ‘Published’
    Completing the Vocabularies

  • How do these relate to the RDA guidance text?
    Who will maintain these? How will they be kept in sync with the text?
    Will the governance model for these be the same as the text? Who decides?
    How can we use these vocabularies effectively?
    What else do we need to identify?
    How should we continue this work?
    • IFLA has followed suit using the Open Metadata Registry to add the ‘official’ FRBR entities, FRAD, and ISBD
    • This provides exciting opportunities to relate all the vocabularies together
    Remaining Issues

  • We wrote about the decisions we made for RDA in DLib: http://dlib.org/dlib/january10/hillmann/01hillmann.html
    Need to continue to disclose what we’ve learned and work on building best practices documentation in this environment
