    • OCLC Programs and Research (PaR) OCLC Research RLG Programs A leading research center devoted to Provides a venue and focus for collaboration, supporting OCLC’s public mission on behalf problem-solving, and the development of new of libraries standards, products, and services among research institutions Conducts applied research Staff with deep expertise in academic Prototypes new systems/services – some research libraries, archives, and museums. prototypes are eventually integrated into Partnership of ~140 libraries, archives, and OCLC products and services museums in 14 countries with: • Deep, rich research collections Active in standards development – OR has been instrumental in the development of • Mandate to make collections accessible key technologies & standards: • Commitment to exploit technology • Commitment to collaboration • PURLs (Persistent URLs) • Dublin Core • Commitment and capability to contribute to • OAI (Open Archives Initiative) ‘commons’ (collections, expertise, • SRU/W (Search & Retrieve) infrastructure)
    • OCLC PaR Organization Lorcan Dempsey Jim Michalko OCLC Research staff RLG Programs staff

    • Brief descriptions Managing the Collective Collection Renovating Descriptive & Organizing Practices - Explore issues and opportunities for - Consider economics of metadata creation gaining value from shared collections and utility of metadata in a networked environment sample activities: - NYARC Collection Analysis - sample activities: characterizing aggregate collection of - RLG Programs Descriptive Metadata selected art libraries Practices Survey Results • Exploring opportunities for evidence-based collaboration Last copies – characterizing content and distribution of unique book holdings • Examining system-wide holdings for shared collection and community profiles
    • Brief descriptions (cont’) Measurements and Behaviors Supporting new modes of scholarship - Understand user behaviors - Address changes to support sample activities: infrastructure for scholarship - Seeking Synchronicity: Evaluating sample activities: Virtual Reference Services from − Investigate scholarly needs & User, Non-User, and Librarian expectations (e.g., data-mining of digital Perspectives (IMLS-funded work with text) Rutgers) − Personal collections - Supporting usability work for − Library-Archive-Museum (“LAM”) WorldCat.org and WorldCat Local relationships interface design
    • Brief descriptions (cont’) Modeling New Service Infrastructure Architecture & Standards - Work towards shared - Contribute to standards understandings, common development and implementation architecture sample activities: sample activities: - OAI-ORE (Open Archives Initiative - Supporting work for Developer’s Object Reuse and Exchange) Network and WorldCat API - OASIS Search Web Services - Creating a special version of Technical Committee OAICat for museum use - NSF Blue Ribbon Task Force on Sustainable Digital Preservation and Access [NYT article]
    • Updates on selected research projects Crosswalk Web Service Terminology services WorldCat Identities VIAF (Virtual International Authority File)
    • Crosswalk Web Service Goal: Develop technology to improve the quality and efficiency of translation of metadata from one scheme to another Delivered: • An innovative and novel approach to the problem • New technology (SEEL [a new programming language], modular design, new code) • Being integrated into OCLC systems (e.g., Connexion, batchload) • Part of technology under the NextGeneration cataloging services
    • 1 Transform to 2 intermediate form STRUCTURAL TRANSFORM File of records in format X SEMANTIC Translate input TRANSLATION semantics to CORE 3 CORE SEMANTIC Translate CORE to TRANSLATION output semantics 5 4 STRUCTURAL TRANSFORM Transform to output format Y
    • Terminology Services Goal: Offer accessible, modular, web-based terminology services Deliverables: • Enhanced, modernized versions of controlled vocabularies in MARC XML, SKOS, more • Addressing identifier issues • Adding cross-vocabulary mappings • Web services to leverage power of disciplinary (‘subject’) thesauri (e.g., DDC, LCSH, MeSH, TGM I and II, FAST, more)
    • Highlights of prototype service • Search descriptions of controlled vocabularies • Search for concepts/headings in a controlled vocabulary • Retrieve a single concept/heading by its identifier • Retrieve concepts/headings in multiple representations including HTML, MARC XML, Zthes, and SKOS. • Search using SRU CQL syntax
    • Vocabularies
    • WorldCat Identities • Using data mining techniques OCLC builds a summary page for persons and corporate bodies referenced in WorldCat bibliographic records (25 million+) • Data is derived from bibliographic data and authority records and holdings in WorldCat • Special features such as a publication timeline included:
    • VIAF (Virtual International Authority File) Primary objectives: 1. Identify the same person or organization in multiple national authority files 2. Link the corresponding authority records Value: • Potentially lowers the cost of authority work • Multiple authorized forms may co-exist • Better data-mining (including FRBR) and searching • VIAF will made available on the Web for wide use by libraries, search engines, others
    • VIAF (cont.) How VIAF works: 1. National libraries supply OCLC with national bibliographic files and authority files 2. OCLC-developed software: • Identifies key relationships (e.g., author name to works, to co- authors, to subjects) • Matches same author with different names • Distinguishes same name but different authors 3. Links between matched authority records are generated and stored
