[Koha] Adapting MARC frameworks and deleting unneeded tags

Thu Mar 16 07:15:14 NZDT 2023

Hi Aida, (this one's going to the Koha list as well)

Based on my quick look, the formats for MARC and UNIMARC are very different, and not really compatible. You can see the complete MARC structure here:
   https://www.loc.gov/marc/bibliographic/
I couldn't find a similar site for UNIMARC, but the Library of Congress has a page of UNIMARC to MARC 21 Conversion Specification:
   https://www.loc.gov/marc/unimarctomarc21.html

Are you really, really sure that you'll never need an ISBN? When I've done Z39.50 searching, that's the first thing I look for. I use MarcEdit though, and I think Koha Z39.50 may let you search than more than one field at a time.

And finally, and not related to your current conundrum, Koha will let you add fields even if they're not MARC or UNIMARC standard. For the past nevermindhowmanyweeks I've been rebuilding the MedStar Authors catalog (the one in my signature is still the old one). For example, I wanted a field for ORCID numbers, so I created the 858 field based on the 856 field, which I use for DOIs. You can also edit the Search Results and Search Detail xsl files to put whatever you want on the OPAC. I'll have more to share on this soon, I hope.

Hello Donna,

Thank you very much! Yes, for theses I don't foresee using fields such as ISBN or some others, and we don't import theses from anywhere else, so I would be fine with removing each field we won't need.

I will check that custom framework, that's very kind of you. I have two separate installations of Koha – one on a work server with UNIMARC flavor as that's what's used in my country, and another on my old personal laptop which is MARC21; does it matter where I upload the framework?

Best regards

Aida Đikić

Hello Aida!

If you are sure you will never be importing records that would have those tags, then yes, go ahead and delete them!  We do custom frameworks a lot for special projects like you mention, and usually delete the extraneous fields.

If you would like to use it, you can access here https://drive.google.com/file/d/196CGH2J_6_UtLUZf7zlo0sybT66NrVxV/view?usp=sharing a framework that we worked with a library to create for their thesis/dissertations.
You can download the framework file as .csv, then import it into a new framework.

The only concern with deleting fields from a framework is that if you import a record that has, for example, an 036, and the framework you are importing the file into does not have that field then the data is lost.
But with the process you are describing, I don't see any issues with deleting certain fields.

Best,
Donna

Hello all,

Today I have another question for you regarding MARC frameworks and cataloging different items. While I wait for our IT to export the cataloged textbooks from our current system, I've been refreshing my knowledge on UNIMARC, going through the exported theses (2008-2018; for later ones I don't have an exported csv file yet) and trying to work out how best to adapt the MARC framework so they can be imported. I've also been looking up the mail archive to see how others have dealth with cataloging theses - if any of you could share your practice I'd be grateful!

I downloaded the Books, Booklets, Workbooks framework I adapted from the Default framework, and in going through the tags I saw there were many I would never use; would these be OK to delete? I mean tags such as 20 Fingerprint Identifier, 21 Legal Deposit Number, or 36 Music Incipit, and others. For the eventual Theses framework, I also would not need tags such as 10 International Standard Book Number (ISBN) or 11 International Standard Serial Number (ISSN) and many other, but would need a tag where I could list the student mentor for that particular thesis. I'd also like to add a Serial publications framework.

Would I actually be safe in deleting these tags, or is there a better way to handle them? In my earlier efforts to add Z39.50 servers, I tested adding a title I had in hand, but I am being prevented from saving it since some of the tags were blank upon import and I wasn't sure how to fill them out.

Best regards

Aida Đikić
