Three Uses for the Semantic Web They include:
* Sideline Semantics (or how to cut down on those darn post-planning columns),
* The Policy Ontology, and
* Cross Domain Searching for Calendar Concerns.

The Policy Ontology was perhaps the most interesting:
"I decided to tackle this with an interface to Jena for Apache Cocoon, or to use Cocoon parlance, a Jena-based transformer. I had no idea what kind of systems sat behind virtual reference applications, but I did know the protocol used underneath the queries was based on SOAP, and Cocoon excels at inserting itself in between any XML stream and adding value to the contents. So my approach was to use Jena's inference capabilities to map different classification schemes based on relationships defined in either RDF Schema or OWL. Yes, you could do the same thing with a table or two, and a thousand other ways, but the ontology approach provides a formal syntax for defining relationships."

Seems similar in idea to Sherpa Calendar.

The application is WIBS.
