Abstract:

The proliferation of digitized resources accessible via Internet and Intranet knowledge bases, and a pressing need to develop more sophisticated tools for the identification and retrieval of electronic resources, both general purpose and domain-specific metadata schemes have assumed a particular prominence. While recent work emanating from the World Wide Web Consortium (W3C) has focused on the Resource Description Framework (RDF), and metadata maps or "crosswalks" have been created to support the interoperability of met metadata standards -- thus converting metatags from diverse domains from simply "machine-readable" to to "machine-understandable" -- the next iteration, to "human-understandable", remains a challen challenge. This apparent gap provides a framework for three-phase research (Howarth, 2000, 1999) to develop a tool which will provide a "human-understandable" front-end search assist to any XML-compliant metadata scheme. Findings fro from phase one, the analyses and mapping of eight metadata schemes, identify the particular challenges of designing a common "namespace", populated with element tags which are appropriately descriptive, yet readily understood by a lay sea searcher, when there is little congruence within, and a high degree of variability across, the metadata schemes under study. Implications for the subsequent design and testing of both the proposed "metalevel ontology" (phase two), and the prototype search assist too tool (phase three) are examined.
