Re: [search-ws] Fw: Advice needed on federated search

["Carl Reed" <creed@opengeospatial.org>]

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:

http://www.inspire-geoportal.eu/catalogues.htm

http://www.ec-gis.org/Workshops/13ec-gis/presentations/5_sdi_technology_III_Voges_4.pdf
http://www.ogcnetwork.net/node/304

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!

Carl

>> Mr. Denenberg,

>> I've been following the work of the OASIS SWS Technical Committee with
