Diane Vizine-Goetz OCLC Research Dewey Users Group ALA Midwinter Meeting 2005 Research Update on Terminology Services Diane Vizine-Goetz OCLC Research

Project Goal The goal of the terminology services project is to make the concepts in knowledge organization schemes and the relationships within and between schemes more accessible to people and computer applications

Approach To develop techniques/web services that can be redeployed in other environments Web services are modular, web-based, machine-to-machine applications that can be combined in various ways

Terminology Services Terminology services are web services for knowledge organization schemes (kos) e.g., authority files, subject heading systems, thesauri, taxonomies, and classification schemes A web service that provides mappings from a term in one vocabulary to one or more terms in another vocabulary is an example of a terminology service, e.g. DDC/LCSH mappings

Schemas Supported MARC 21 formats for authority and classification data SKOS core, an RDF schema for thesauri and related knowledge organization schemes Zthes version 0.5
