Re: [search-ws] RE: APP?

["Ray Denenberg, Library of Congress" <rden@loc.gov>]

Yes Farrukh I think you misunderstood.  His suggestion is to scrap SRU,
start over and build a protocol based on the Atom Publishing Protocol.

I think that this notion about starting from scratch needs some strong
clarification.  We now have 20-25 years of intellectual capital accrued in
Z39.50 including the past seven years with sru/srw. We are not starting from
scratch.

(The issue of response format is relatively minor in comparison, and one
that we will resolve without too much trouble I think. I'm going to post a
proposal on that soon, I hope.)
