As with most things related to RDF, we need some conceptual clarity with regards to what things are and how they are implemented in Virtuoso. Inference Rules: A set of rules defined using a domain specific language (e.g., swirl, rif, spin, etc.) that determine the evaluation relationship types (relations) when producing a query solution. Virtuoso & Inference Rules: Current editions of Virtuoso support canned inference rules that support relationship types described by RDFS and OWL ontologies [1]. The commercial edition of Virtuoso 8.0 (next release) will add support for custom inference rules using either of the following: [1] SPIN vocabulary -- which boils down to using SPARQL as a Custom Inference Rules Language [2] Virtuoso Macro Language -- same thing, but at a lower level while still being based on SPARQL.
