Subject: RE: [search-ws] Fw: Advice needed on federated search

We need to come up with a document that outlines the effort (comparative ease) to move from OpenSearch to SRU which also compares upgrading OpenSearch with some missing elements in a way that is compatible with Oasis SWS.  Our SWS binding analysis didn't seem to do the trick.
