Some particular service could provide a DAWG conformant interface to a virtual knowledge store which constitutes a federation of heterogenous knowledge from a broad range of disparate repositories -- but a DAWG agent should not be concerned with, or even be aware of, such federation. Such a service would be very useful, and I expect it to be done often, but it has IMO no affect on how queries are expressed and submitted to services for resolution. The same goes for any form of distributed query. (or have I missed something more fundamental, Alberto, in your test case?) Patrick Patrick Stickler Nokia, Finland patrick.stickler@nokia.com
