1. ZEBRA XPATH INDEXING. Zebra, could support multiple MARC semantics simultaneously with a meta-record XML design using XPath indexing in Zebra. I have some work toward the specification of such a design. Do not expect to see this anytime soon. 1.1. TUMER'S CODE. I composed an unsent message for the development list about the code being developed by Tumer Garip at Near East University (NEU) in Cyprus which uses meta-records. That unsent message includes some reference to future develolpment which could include multi-MARC Koha. I never received an answer to my qualifying question from Tumer so I did not post my message. Maybe Paul's recent post in the thread about making a separate place for Tumer is some sort of answer but my message may need some revision before posting. Tumer's code is unfortunately partly an independently maintained fork of Koha because he needs it in his production environment and cannot wait for the rest of the Koha community to catch up. There are other issues about technical problems he has had committing to CVS recently. 2. MARC SEMANTICS CONVERSION. I believe that simultaneous multiple MARC support has significant advantages over necessarily imperfect record conversion but it may be the only route if you need something soon. MARC 21 and UNIMARC do not have a one to one mapping between them and some loss of specificity is inevitable in either direction. 2.1. LC UNIMARC TO MARC 21 MAPPING. The LC mappings are out of date and incomplete. The documentation acknowledges the liability for incompleteness and no support from LC for keeping it up to date. They are however a useful starting point for conversion. 2.2. USEMARCON CONVERSION. USEMARCON was originally developed as a proprietary application before a version was released as free software by the British Library. However, at least early releases included no conversion files which had only been available as part of the proprietary application. The documentation suggested that you should write your own conversion files. If you had access to the conversion files written by someone else, then that would not be an issue. Maybe some conversion files are now included but I have not looked recently. 2.2.1. USEMARCON IN ZEBRA. Tumer has reported that USEMARCON is included in Zebra and may have some conversion files but I have not had time to investigate that. 3. REASONS FOR NEEDING SIMULTANEOUS MULTIPLE MARC SEMANTICS. I have my own reasons for needing simultaneous MARC semantics in the catalogue but I am very much interested in knowing whatever reasons others may have. There is are some catalogues in Taiwan which simultaneously return some records in semantics based on USMARC or MARC 21 and some based on UNIMARC. I did not find it possible to specify a record semantics to be returned when the catalogues was queried so I had to write a routine in my Z39.50 client code to recognise the difference for semantic parsing of the result set. My Z39.50 client was started when Perl bindings were insufficient and it has not yet been ported to Perl. I had assumed that most people would be satisfied with some mostly accurate record conversion although I am not satisfied with a necessary incompleteness of the conversion. 4. OTHER SIMULTANEOUS MULTIPLE MARC SOFTWARE. I am unfamiliar with the extent to which other library software has support for simultaneous multiple MARC semantics. I have some guesses that some software does have such support, however, this is really a minority issue except for national libraries and some union catalogues. I am uncertain whether the different record semantics were indexed centrally in the case of the catalogues that I know of in Taiwan. This may be an issue for the European Library union catalogue. I would be pleased to have any reports of what the actual extent of support is in other software.

hi,programmers

zebra support multi-marc ?

i run koha for mysql can support coexistent marcs (marc21 & unimarc).

Hello long_sam,

Koha can handle UNIMARC and MARC21, but not for a given setup : you have to choose one and can use only this one. In the future, we may/could add some facilities to do MARC21 ->UNIMARC and/or UNIMARC -> MARC21, but that's unplanned yet.

Hi all, I hope this is the place to ask such a question... I recently installed Zebra and it seems to be exactly what I need! However, my entire database is in Unimarc whereas the distribution I downloaded (2.0.14) contains the files needed for USmarc (.abs, .tag, .flt etc). Could somebody please tell me where I can find those files for the Zebra to work with Unimarc records? My records are in ISO2709 form but I could easily convert them to marcxml-unimarc. Any help would be greatly appreciated!...
