I'm wondering whether we need a ZING update service when we have the OAI which does update the other way around. With OAI the client is on the database side, seeking records from known locations to update. There is no need for authentication as with ZING where the clients can be anonymous. OAI could benefit with some of the data structures defined in the UCP that enable unambiguous modification and delete. Janifer ............................

I am of the growing opinion that a full record presentation should be by a specific URI for each record rather than a position in a result set. (Better for bookmarking and caching.) Of course this could be achieved outside of SRU by including the URI in the record. An update could use the http "PUT" method using the record URI. http should handle the authentication. This leaves the issue of how to encode the updated record. Bill (P.S I'm also on holiday for a week. So I can't reply until I'm back.) -----Original Message----- From: Ray Denenberg [mailto:[log in to unmask]] Sent: 22 May 2003 16:16 To: [log in to unmask] Subject: [Fwd: SRU: Database Update Extended Service] This is a note sent to me, which would be posted to this list except the list is private, for implementors only. So two questions: 1. any opinions on how our "new generation" Z39.50 might treat update, if at all? 2. how should we treat questions like this, open up the list? start a new, public list, for discussion? --Ray -------- Original Message -------- Subject: SRU: Database Update Extended Service Date: Wed, 7 May 2003 11:52:58 +0200 From: "Kett, Jürgen" <[log in to unmask]> To: "[log in to unmask]" <[log in to unmask]> To whom it may concern, I have a question: In SRU there is currently no operation comparable to the "Database Update Extended Service Facility" of Z39.50 (EXT1.5 in the Z39.50 Document). Will an related operation be introduced in the future?
