Questions about rdfs inference
Hi all,
I am planning to modify the code of rdfs inference in jena, actually I need to add some more rules for domain need.. Does anyone know which part of the code I need to modify???
Thanks a lot..

In fact, we did change the model of rdf, which is rdf with annotation, so it's not traditional triple.. And therefore, i believe simply modifying rdfs.rules will not work… But anyway, thanks for your help..

Do you need to change rdfs inference in Jena, or do you just
need to create a new inference model with different rules?
Jena's RDFS inference is mostly just some particular rules
supplied to a rule-based reasoner. You can supply your own
rules (based on the default RDFS rules) to do whatever you
want.
The default rules are in etc. Depending on your requirements,
I think you want to start with rdfs-fb.rules or rdfs.rules -- the fb
set uses hybrid inference (forward rules which can generate
backward rules), while the rdfs.rules can I think run in either
direction since they're not hybrid.
