Abstract

Internet resources are not yet machine-understandable resources. To address this problem a number of studies have been done. One such a study is the Resource Description Framework (RDF), which has been supported by World-Wide Web (WWW) Consortium. The DC (Dublin Core) metadata elements have been defined using the property of extensibility of RDF to handle electronic metadata information. In this article, an authoring editor, called H-DCEdit, is introduced. This editor makes use of RDF/DC model to define contents of Turkish electronic resources. To serialize (or to code) a RDF model, SGML (Standard Generalized Markup Language) has been used. In addition to this work, a possible view of RDF/DC documents is provided using Document Style Semantics and Specification Language (DSSSL) standard. HDCEdit supports use of Turkish language in describing Internet resources. Isite/Isearch system developed Center for Networked Information Discovery and Retrieval (CNIDR) organization with respect to Z.39.50 standard is able to index documents and allows one to query the indexed terms in tagged elements (e.g., terms in RDF/DC elements). In the scope of our work, the localization of this Isite/Isearch system is completed in terms of sorting, comparison, and stemming. The feature of supporting queries over tags provides basis for integrating H-DCEdit authoring tool with Isite/Isearch search engine.
