This is an implementation report for SPARQL 1.1 RIF Core Entailment using the SILK rule engine [1].

SILK passes the following entailment tests

   rif01
   rif03
   rif04
   rif05
   rif06

with the following caveats that don't directly affect RIF Core Entailment via SPARQL 1.1:

   SILK doesn't currently implement RIF Import.  I just loaded the referenced files explicitly.

   SILK doesn't currently implement RIF builtins.  I provided a stub for <http://www.w3.org/2007/rif-builtin-predicate#iri-string>(?z, ?x))

   SILK doesn't currently handle prefixes containing ., such as the j.0 generated by Jena.  I changed the prefix to remove the .

Thanks!

	Mike
