Hi Mike

For service-level metadata, the GSDI registry has indexes for 
both the place where the collection is hosted and the coverage 
area of the content of the collection. These GSDI records (see 
http://registry.gsdi.org/browse.php?order=title and choose any 
record) are mapped as GILS records for searching. Search also 
interoperates with UDDI and ebRIM service registry clients. 
I can send you the pqf.properties file for a YAZ implementation, 
if you like. Also, you can see how this service registry search 
chains to collection search at http://www.search.gov/gsdi/ge.ppt
