Ray -
In the geospatial community, there has been considerable discussion,
research, and implementation of federated catalogues that federated search.
This is especially true in the earth observation community (which DoD should
have a great interest in). Numerous references including:

I know that these are quite a few links :-)
Also, they should check out what the Canadian community has done as part of
the Canadian Geospatial Data infrastructure. They have implemented a
federated (national) distributed catalogue and search capability based on
Z39.50
Hope this helps!

>> Mr. Denenberg,
>>
>> I've been following the work of the OASIS SWS Technical Committee with
>> interest. The organization I support, Intelligence Community Enterprise
>> Solutions (ICES), is part of the Director of National Intelligence CIO
>> organization, and provides search and discovery services that allow the
>> sharing and integration of information between the intelligence agencies
>> and their customers. In addition to providing search tools (as well as
>> other community services) on Intelink, ICES is also the DoD's managed
>> service provider for Content Discovery on its secret and unclassified
>> networks.
>>
>> As you may know, the DoD developed a Search Web Service specification
>> under the Horizontal Fusion program back in the 2003-2004 time frame.
>> Since then, the IC and DoD have tried, unsuccessfully, to arrive at an
>> updated, joint federated search protocol. There's general support for
>> using a combination of Atom, OpenSearch, and the Defense Discovery
>> Metadata Standard (DDMS) as the basis for a new specification. However,
>> we haven't come to agreement on query syntax or Web service style (SOAP
>> vs. REST). Our decision on Web service style is very much affected by the
>> access controls on some of the content sources, and use cases that
>> involve federating searches across security domains.
>>
>> Our organization would appreciate your input on some very near-term
>> decisions we need to make in this area. Specifically, what protocol(s)
>> would you recommend we implement this year (and what should we avoid), in
>> order to line up with the direction you see the OASIS work going? Also,
>> what direction do you see commercial product support going in this area?
>>
>> Please call me at the number below if you'd like. We can also arrange to
>> visit your office, or host a visit to ours as your schedule allows.
