On batch edits of records and items, I'm using Koha Tools and MarcEdit. On record matching rules for re-import, we cannot make use of ISBN or ISSN as neither have been used in legacy catalogue. We've been advised to use Koha biblio number as the unique identifier. Might anyone be able to share settings for a record matching rule on the Koha biblio number, 999c? I looked in the manual, but it didn't seem to provide enough info for me to actually set up this rule. (http://koha.org/documentation/manual/3.0/administration/catalog-administrat ion/record-matching-rules ) For testing, I'm exporting a single biblio *.mrc, making edits w/ MarcEdit *.mrk, re-compiling to *.mrc, then staging w/ Koha Tools. Koha then gives me a no_match on the record, so I suspect that I've used incorrect settings. Using the ISBN rule as an example, I set up the following: -------------------------------------------- Matching rule code: KBiblio Desc: 999$c Match threshold: 1000 Match points - Search index: KBiblio (Do I need an actual Koha index, or just make something up?) Score: 1000 Tag: 999 Subfields: c Offset: 0 Length: 0 Normalization rule: KBiblio (Do I need an actual Koha rule, or just make something up?) If I need actual Koha search index and/or normalization rule, pls cite URL in manual.
