Hi Morris,
this document contains examples for the idea of using XQuery to express requirement on an XML-based resource description (in this case this is GLUE 2.0)
The advantage of this approach is that JSDL is not bound to a set of terms and does not need to be changed according to the evolution of the information model.
Cheers, Sergio
