It's funny OCLC seems to be doing quite an admirable job of creating URIs for bibliographic records: http://worldcat.org/oclc/30436563 I will admit I'll be sad to see SRU going down the road of yet-another xml format. But I can appreciate Rob's argument about wanting to be explicit. BTW I did ping the OpenSearch list and have found out that Dewitt Clinton and possibly Joe Gregorio and James Snell will be working on an IETF RFC for OpenSearch. So perhaps it would make sense for SRU/OASIS to distinguish itself from such an effort by having its own specialized response format. Ahh, standards ... //Ed [1] http://groups.google.com/group/opensearch/browse_frm/thread/66c2e5c78a0ede6b
