Abstract:Interoperability issues pose a barrier to sharing and exchanging information among digital libraries and repositories. This is due to the use of diverse metadata standards, and their different degrees of generality or specificity. This causes loss of information at all metadata model levels (e.g., schema, schema definition language, record, and repository). As a possible solution, the roles for a Common Terminology (CT) based on the DCMI abstract model are proposed. Common Terminology (CT) is to improve interoperability by allowing communities to use their own standards while providing uniformity to searching. Taking commonly used standards (MARC, MODS, DC, and QDC) as bases, CT has developed as a bridge across different generality and specificity levels. The developed CT is a set of 12 Common Terms (properties) and 58 qualifiers (sub-properties) with CTScheme. CT is represented as XML schema, RDF schema, and SKOS concepts. The performance of CT in achieving and improving metadata interoperability is presented through empirical evaluations. The experiments for CT are conducted with Harvard (MARC), MIT (QDC), and UIUC (MARCXML) metadata records through cooperation of three universities in the USA. CT minimizes considerably loss of information reducing the gaps among them. CT increases significantly accuracy in mappings showing high lexical and semantic match rates. The planned prototype will provide a portal for Harvard, MIT and UIUC libraries with the built Linked Open Data and CT union catalog, connecting their several million online accessible records on the Web. CT will give an assured solution to improve interoperability for university libraries and further for libraries and organizations to cooperate in sharing information reducing loss of information at multiple metadata levels.
