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


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
