A Windows GUI application for RDF. SWC is a client tool for a Sesame 2 RDF server or SPARQL endpoint, and can be used as a out-of-the-box local triplestore. It offers advanced SPARQL querying and handles Sesame server administrative tasks.
This tool is no longer actively maintained as my priorities and interests have shifted away from .Net development. If you are interested in taking over, drop me a line.
