I can’t speak to LRM at all, but it reminds me how perhaps we should start moving towards uncoupling some parts of Koha and thinking more about how the different aspects should/could interact with different metadata models. I think Paul has already targeted the most important thing and that’s search. Users don’t care what metadata model is in Koha. They just want to be able to find the resources they desire. So whatever we do… I think we should put OPAC users of Koha first and then work backwards.

[was Re: What is biblioitemnumber for?] Hello Stefano, What you're pointing Stefano is very important: we must start our effort toward LRM. Here is my 1st thoughts about it: I think that LRM support on Koha means 2 things: * internal handling of the LRM model. This would mean breaking the biblio/items structure of the database, managing "LRM records" (if we have), proposing LRM cataloguing tools, and changing many many other things in Koha (like MARC staging, z39/50 search, ...) I feel that this will require years and a lot of work, and for now the national catalogs are not ready to propose that. * new search paradigm. What the Oslo Public Library made is very interesting. when you do a search, you get the works (author/title/copyright date), then can see the expressions that exists in the library (publication dates, material type/support), then the items. Example: XXXXX I don't know in US, italy or other countries, but in France the BNF is working hard on adding "LRM" fields in their catalogue. This is done by adding new MARC fields (a lot...), that will contain an ARK to the linked data (work, authors, place, subject, ...). Last week, there was a meeting at the BNF where they presented their plans for 2019. BibLibre has not yet started to investigate the effort to create a "LRM-UNIMARC-Elastic Search" in Koha, but, for sure that's something we'll investigate in 2019. If anyone is willing to join the effort, let me know (even better: if you are interested in LRM-MARC21-Elastic, the idea being to have a flexible configuration). If anyone has information regarding LRM-MARC21-LoC plans, feel free to share ! Have I missed something ? What are your plan regarding IFLA-LRM ? What's next ? Le 19/11/2018 à 16:58, Stefano Bargioni a écrit : Paul, very interesting the basic historic idea. What you wrote, helps me to say that with Elasticsearch, Koha has the possibility to adopt definitely the LRM [1] model, that is going to be implemented in RDA [2]. Especially important IMHO are links among authorities. Or, better, links of any type.
