back to ViewDefinitionLanguage


In order to support chaining of non-materialized views, we prefer our ontology view definition language (VDL) to be the same language as our query language (closure property). As such, we began by looking at query languages over RDF (or RDFS or the various forms of OWL). Although we read about several such languages (including RQL, RDQL, SeRQL, Triple, Versa, RVL, etc.), we decided to focus our initial attention on SparQL as it has W3C candidate recommendation. SparQL already had a lot of traction in the Semantic Web community as well as several engine implementations. We thought it prudent to look first to the standards (or closest things to a standard) and see if these were sufficient for our needs or could be extended to meet our needs.
