I am not familiar with CORBA or OMG so if you don't mind, I have
a couple of simple questions: 

	Is the query service intended to be similar to SQL?

	Are the functions get_child_values() and get_descendent_values()
	the primary methods for traversing a graph?

Thanks.

The main elements of this are:

- CORBA interface for queries against RDF-model oriented data
- CORBA encoding for resource descriptions (query results)
- use of RDF-schema for the meta-data

Admitedly, only the latter feature involves XML and RDF-syntax, so this is
probably not exactly what you had in mind.  But the rest is all RDF-model
based and so you may be interested in the choices we made in the query
design.
