Java RDF framework for knowledge repository

This paper describes basic features of a client library called persistence API that provides access point to knowledge repositories based on RDF standard. Persistence API (P-API) has been implemented within FP6 IST project called knowledge practices laboratory in order to separate business logic from data representation in RDF. This approach enables simple integration and communication between end-user applications and knowledge repository. The development of P-API is still ongoing, with new features such as support for search services implemented in recent releases.
