Semantic Web Implementation using jena

Image
Abstract:
This paper investigates the possibility to utilize standardized semantic Web-based languages, such as RDF and OWL. Jena is Java toolkit for developing semantic web applications based on W3C recommendations for RDF and OWL. It provides an RDF API, ARP, an RDF parser, SPARQL, the W3C RDF query language, an OWL API, and rule-based inference for RDFS and OWL. Jena is open source and grown out of work with the HP Labs Semantic Web Program. Keywords:
RDF, OWL, SPARQL, W3C, API, ARP, XML, HTML, ONTOLOGY, METADATA, MODEL, FACTORY, JENA, JAVA, JDK etc. Introduction:
Some aspects of W3C's RDF Model and Syntax Specification require careful reading and interpretation to produce a conformant implementation. Issues have arisen around anonymous resources, reification and RDF Graphs. These and other issues are identified, discussed and an interpretation of each is proposed. Jena, an RDF API in Java based on this interpretation, is described. Jena works in Linux, windows and Free BSD. We need…
