Digital Semantics: Automated Metadata Capture Translation and Delivery. Tony Chirkos (OCLC Online Computer Library Center)
OCLC has multiple projects underway to capture technical, structural, administrative, descriptive, and preservation, metadata. The metadata is captured from many alien sources, including Dublin Core, common .MIME file types, vendor inventory systems, Web Sites, etc. OCLC is working on methods of capturing this data and translating (that is, cross-walking), it into MARC and other formats. After cataloging enhancements and quality control, the data may be delivered to libraries in MARC and also in other formats including ONIX, Dublin Core, and other output formats. All of these projects are in various stages of development and thought at OCLC. The presentation will give an overview of the various efforts, the prominent metadata schemes, how they fit together, and how the projects will help libraries crosswalk, enhance, and manage collections using the various types of metadata semantics, metadata input schemes, and metadata output formats in the digital library environment.
