Hi all! Norway will soon have a new meta-search for libraries, based on harvesting records through OAI-PMH and creating a central index. One of the requirements for getting into the meta-search is that the last part of the OAI-PMH record identifiers (e.g. "2" in "oai:bibkat.no:NO-1120127:2") corresponds to the contents of MARC field 001. What it actually looks like does not matter too much, as long as it is a *locally* unique identifier for the record. An easy fix for this would be to put the biblionumber into MARC field 001. Is there a way to do this without changing the code of Koha? E.g. some trick with frameworks and mappings? I have tried to think of something clever, but have come up empty handed... (I have created a bug related to this, suggesting that 001 always be used as the identifier for OAI-PMH, or that a syspref be created to let a library choose whether to use biblionumber or 001 as identifier for OAI-PMH: http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6198 ) Best regards, Magnus Enger libriotech.no
