Remember Bath was developed in 1999 and Bib-2 was far from being universally available then. At the meeting in 2002 in Dublin it was decided not to reference Bib-2 in the new release 2 of Bath since it was more important to nail down the holdings specifications and work with vendors to implement them than to change the attribute architecture on the large base of installed Z39.50 library systems using Bib-1. The discussions in Dublin also indicated that there were still some issues with Bib-2 and the interpretation of all the Bath searches, which now include searching of authority files.

Hi Barbara. I am very sympathetic to your complaint about the AA and BIB-2 being overlooked, and I very much agree that we should all be doing all we can to ensure that these unarguably superior technologies be used in preference to BIB-1 wherever appropriate. That said, I get the impression that the NORZIG people have a system already established, and that they merely want to extend it (if any NORZIGgers are on this list, maybe they can confirm or deny?) If that's correct, then it seems a bit harsh to require them to throw out all their existing search-profiling and start from scratch with the Attribute Architecture. So I'm really keen on the AA -- you'll have noticed that I used it and it alone for the search specifications in both the Zthes profile (zthes.z3950.org) and ZeeRex (explain.z3950.org) -- but I don't think we can hope to successfully impose it on communities that are already 90% of the way through implementation. > I note that in the recently released specs for an IMS Digital > Repositories Interoperability specification > http://www.imsglobal.org, there are guidelines for the use of Z39.50 > and a proposal for an extensive extension of bib-1 for IMS > Meta-Data. Why not take the opportunity to use the new attribute > architecture there? The only reference I could find to Z39.50 on that site was in the IMS Digital Repositories White Paper at http://www.imsglobal.org/imsdr_whitepaper_v1p6.html which says: Searching allows the portal to send the same query to many content providers, retrieving results from each, merging them, and then presenting them to the user. Searching is facilitated through the use of Z39.50 and the Bath Profile. It is not necessary for portals to talk directly to content providers in all cases - brokers may take queries from portals and fan them out to multiple content providers. A broker uses Z39.50 to talk to both the portal and the content provider. It doesn't seem unreasonable to me that this project, in which Z39.50 appears to play a very small part, should use the Bath profile, which has a great deal of international recognition. (What I do think is an absolute crying shame is that Bath decided to go with BIB-1 in the first place, when BIB-2 was -- just -- available to be used instead. That was the moment of opportunity to Save The World.) By the way, none of this should be construed to mean that I am particularly fond of the specific access points that the NORZIG propose. I'll comment separately on them. _/|_ _______________________________________________________________ /o ) \/ Mike Taylor <mike@miketaylor.org.uk> www.miketaylor.org.uk )_v__/\ "Oh, don't be so sentimental mother, things explode every day" -- Monty Python. -- Listen to my wife's new CD of kids' music, _Child's Play_, at http://www.pipedreaming.org.uk/childsplay/
