WS-DAIOnt-RDF(S): Ontology access provision in Grids

This paper presents WS-DAIOnt-RDF(S), a system that provides an homogeneous access mechanism for using heterogeneous and distributed RDF(S) ontologies in Grid applications. These ontologies may be stored in different RDF(S) storage systems, geographically distributed across the Grid infrastructure. The paper describes in detail the design of the system, its rationale, the current implementation, and the ongoing standardisation effort
