Re: BRMS ( Rules ) and RDF for real life application; State of the Art?

hi Aldo,

if you want to describe all your data in RDF, you could have a look at  
the general purpose rule engine of Jena.
http://jena.sourceforge.net/inference/#rules

Jena2 includes a general purpose rule-based reasoner which is used to  
implement both the RDFS and OWL reasoners but is also available for  
general use. This reasoner supports rule-based inference over RDF  
graphs and provides forward chaining, backward chaining and a hybrid  
execution model. To be more exact, there are two internal rule engines  
one forward chaining RETE engine and one tabled datalog engine - they  
can be run separately or the forward engine can be used to prime the  
backward engine which in turn will be used to answer queries.
