Virtuoso Facets API

The Virtuoso Facets API is a general purpose RDF query facility for facet-based browsing. Faceted browsing is a technique for accessing information organized according to a faceted classification system, which classifies each information element along multiple explicit dimensions. This API takes an XML description of the desired view and generates the reply as an XML tree containing the requested data. The user agent or a local web page can use XSLT to render this for the end user.
