rdfQuery is an easy-to-use Javascript library for RDF-related processing. You can use it to parse RDFa embedded within your page, query over the facts it contains, and reason to produce more facts. In concert with an server-side triplestore, rdfQuery can be used to create interfaces for editing the semantic web.

rdfQuery comes in three flavours, with a minimised and a full Javascript release for each. The three flavours are:

• Core rdfQuery enables you to create triplestores and query over those triplestores
• rdfQuery with RDFa supports parsing RDFa and adding it to your page
• rdfQuery with rules supports reasoning over triplestores using rules

To get started, download the latest release and read the tutorial or the reference documentation.

rdfQuery depends on jQuery and, if you want to create serialised versions of JSON/RDF, the jQuery-JSON plugin, which need to get hold of separately.
