D2R Server is a tool for publishing the content of relational databases on the semantic Web. Database content is mapped to RDF (Resource Description Framework) by a declarative mapping which specifies how resources are identified and how property values are generated from database content. Based on this mapping, D2R Server allows Web agents to retrieve RDF and XHTML (eXtensible HyperText Markup Language) representations of resources and to query non-RDF databases using the SPARQL query language over the SPARQL protocol. The generated representations are richly interlinked on RDF and XHTML level in order to enable browsers and crawlers to navigate database content.
