  2. Beyond the Record: OCLC and the Future of MARC • The OCLC Context • OCLC’s Role in RDA • Beyond MARC • Beyond the Record

  3. The OCLC Context

  4. The OCLC Context • A membership organization • Diverse membership

  5. The OCLC Cooperative 69,826 libraries in 112 countries 1,355 5,639 55,284 4,253 1,080 882 1,015 320

  6. OCLC’s Role with RDA

  7. OCLC & RDA • Committee Contribution: • ex-officio membership in the ALA Committee on Cataloging: Description and Access • MARC Advisory Committee • Staff Participation: • Joint Steering Committee's two RDA Examples Groups • RDA/MARC Working Group • Representation on: ALA ALCTS RDA Implementation Task Force • Various program sessions

  8. OCLC & RDA • OCLC Internal Activities: • Discussions with the three U.S. national libraries to plan for the testing/evaluation period (late 2009) • Planning for MARC21 format changes to support the testing/evaluation period • OCLC Contract Services to staff have been selected to participate in the testing/evaluation period.

  9. Beyond MARC21 With thanks to Jean Godby of OCLC Research

  10. The Crosswalk Web Service at OCLC • Enables OCLC to translate from one metadata format to another. • A “metadata format” is a triple that consists of a metadata schema, a structural encoding, and a character encoding. • Supported standards are bibliographic, but the software can handle other types of data. • Can be called from any product or service that processes metadata. • A version with a slightly different interface resides on the OCLC Enterprise Bus.

  13. In sum… • The Crosswalk Web service is engineered for reusability. • It is abstract enough to handle any kind of metadata markup. • It keeps a close connection between human-generated translation logic and executable code. • It is flexible enough to handle many use cases.

  14. Adoptions • The Crosswalk Web Service has been incorporated into: • Connexion Client 2.0 • ContentDM Ingest • Data Load Enhancement • eSerials, eSweep • NetLibrary • Next Generation Cataloging • Adoption is being studied for components of: • Digital Collection Gateway • WorldCat Cataloging Partners NCIP (NISO Circulation Interchange Protocol) • It is being used in research projects: • Art and natural history museum metadata (with RLG partners) • ISO 8459 bibliographic message exchange (with Janifer Gatenby)

  15. Future priorities • Develop a user interface that accepts translation logic and automatically generates Seel scripts. • Streamline and enhance some of the Seel language features. • Investigate ways to interoperate with the crosswalking software developed at OCLC Leiden. • Develop translations for non-bibliographic metadata.

  16. For more information • 1. Metadata translation at OCLC, pre-CWS • A Survey of Metadata Translation Activity at OCLC • 2. CWS documentation • The Crosswalk Web Service Users’ Guide • The Seel tutorial: Introduction; Seel in a Nutshell • 3. 4. Research reports • Encoding Application Profiles in a Computational Model of the Crosswalk • Toward element-level interoperability in bibliographic metadata • A Repository of Metadata Crosswalks • Two Paths to Interoperable Metadata

  17. Beyond the Record With thanks to Diane Vizine-Goetz of OCLC Research

  18. WorldCat Identities

  19. FRBR Entity Levels Revisited The movie Original Version Based on a graphic in Tillett, Barbara "AACR2's Strategic Plan and IFLA Work towards an International Cataloguing Code“ (2002)

  20. OCLC FRBR Work-set Algorithm • Provides a FRBR-based view of the data • Records clustered into works using author and title fields from bibliographic and authority records • Author names and titles normalized to construct a work key • All records with the same key are grouped together in a work set or cluster

  21. Share data elements across a FRBR Work Set

  22. Work pages beta Provides a rich context from cataloging data
