I don't have a "legal department to challenge the patent", but in case it helps:


This was work I did around 2002-03, and includes use of RDF technologies to set 
access controls on a Cisco IOS router, which appears to correspond to the first 
primary claim of the patent:

1. An enforcement system for enforcing policies with regard to service requests 
comprising a processor-readable, non-transient medium storing code representing 
instructions that when executed at a processor cause the processor to implement: 
a plurality of enforcer agents adapted to enforce policies; at least one 
explorer agent adapted to evaluate policy enforcement capabilities available to 
the enforcement system; and a policy decision point adapted to identify the 
policies that need to be enforced for a service request and to pass this 
information to at least one enforcer agent to enforce the identified policies.

I recall there was also an Internet draft published about this time that talked 
about using RDF in a network management control layer: see
