Orac: An RDF/OWL metadata store
using MySQL for persistence, Java servlets for interface, and Jena for modeling
While much of the promise of the Semantic Web lies in creators describing their own content, much of
it surely also
lies in the ability to describe other people's content. Since these descriptions cannot be attached to the content, a
centralized server for metadata is needed. Further, a Web-based front end is needed to allow the largest number of
people to contribute metadata. Jena is an open-source toolkit from HP Labs that provides a Java API for RDF models,
and that implements persistence through a relational database. This project undertakes to create Java servlets that
can present a familiar Web-based interface to users, accept arbitrary RDF schemas, store corresponding RDF metadata,
expose the metadata as HTML or as RDF/XML, and perform simple queries and inference...
