OWL/XDD Application Profiles Photchanan RATANAJAIPAN Ekawit NANTAJEEWARAWAT Vilas WUWONGSE Publication IEICE TRANSACTIONS on Information and Systems Vol.E90-D No.10 pp.1611-1620 Publication Date: 2007/10/01 Online ISSN: 1745-1361 DOI: 10.1093/ietisy/e90-d.10.1611 Print ISSN: 0916-8532 Type of Manuscript: Special Section PAPER (Special Section on Knowledge, Information and Creativity Support System) Category: Keyword: application profile, metadata schema, OWL, XDD, Full Text: PDF(420KB)>>
Summary: An application profile specifies a set of terms, drawn from one or more standard namespaces, for annotation of data, and constrains their usage and interpretations in a particular local application. An approach to representation of and reasoning with application profiles based on the OWL and OWL/XDD languages is proposed. The former is a standard Web ontology language, while the latter is a definite-clause-style rule language that employs XML expressions as its underlying data structure. Semantic constraints are defined in terms of rules, which are represented as XDD clauses. Application of the approach to defining application profiles with fine-grained semantic constraints, involving implicit properties of metadata elements, is illustrated. A prototype application profile development environment equipped with metadata validation features has been implemented based on the proposed framework. | ||||||||||
