Re: [rules-users] Using RDF and RDF Schema to enable dinamic data model

For one thing, DRL comprises almost all of Java's syntax defining "expression". Then, there are the extensions for writing Conditional Elements. Last, but not least, even RHS may have to be parsed for converting statements accessing the RDF facts, unless you manage to permit updates against the basic RDF facts. Drools is designed to work with bean-style pojos. Using subject-predicate-object triples to represent a bean with n fields requires n facts instead of one which will increase your memory footprint. There's also some performance impact to be expected as insert/modify/retract on smaller units will inevitably cause more work by the Engine with activation creation and deletion. The compiler will have to avoid antipatterns in the generated LHS code. Have you looked into the newly introduced feature of traits? -W
