Hi,

We are looking at SPIN as an alternative to define and execute user-defined rules. It is very expressive and in that point looks superior over Jena, SWRL and Oracle type of user-defined rules with IF (filter) -> THEN type of syntax. Although, SPIN is TopQuadrant's, it is entirely SPARQL, and Oracle supports SPARQL CONSTRUCT via Jena Adapter. TopBraid Composer provides and excellent tool support and rule editor for SPIN rules as well.

There is no problem to execute SPIN rules via Jena Adapter, and I believe even via TopQuadrant's SIN API, which is TopQuadrants's SPARQL based infrence engine's API.

My question is about whether Oracle has looked into supporting SPARQL CONSTUCT based user-defined rules in its native inference engine?
Do you have a recommendation for how to use SPIN based user rules in combination with Oracle inference today?

Thanks
Jürgen
