Hi, I'm about to import around 7,000 P2347 mappings (YSO ID authority links) between Wikidata items and YSO (General Finnish Ontology) concepts to Wikidata using QuickStatements2. I'm following the excellent example of Joachim Neubert's work at ZBW, documented e.g. here: http://zbw.eu/labs/en/blog/wikidata-as-authority-linking-hub-connecting-rep… The mappings were collected from several sources: 1. Mappings between KOKO (related to YSO) and Wikidata curated by the Finnish Broadcasting Company Yle (kindly given to us, but not publicly available AFAIK) 2. Indirect mappings derived from Wikidata-LCSH and YSO-LCSH mappings 3. Algorithmic matching suggestions for frequently used YSO concepts In all these cases, the mappings have been verified by vocabulary managers here at the National Library of Finland, so we're not just blindly copying the information from the above sources. I'm wondering about whether to add source/qualifier statements to the mapping statements I'm about to add. I see that in most cases, authority links don't have any source information. For this batch, I could potentially document several bits of provenance information: 1. Where the (suggested) statement originally came from (e.g. Yle and/or indirect LCSH mapping) 2. That we have verified it here at NLF I see that Joachim used source statements like this for his imported links: title (P1476): Derived from ZBW's RAS-GND authors mapping (English) reference URL (P854): https://github.com/zbw/repec-ras/blob/master/doc/RAS-GND-author-id-mapping.… Is this still best practice or should I use something else? Or just import the raw links without any qualifiers or sources? Thanks in advance, Osma -- Osma Suominen D.Sc. (Tech), Information Systems Specialist National Library of Finland P.O.

Thanks Denny. Do you have a practical suggestion how to do this? There's no obvious source URL to refer to currently. What Joachim did was to set up a small document on GitHub and refer to that in the statements. Should I do something similar here? -Osma Denny Vrandečić kirjoitti 12.3.2020 klo 20.35:

When we were uploading the links to Freebase, we also added references fro these. And since you've gone through all this work (thank you for that!) verifying the links, I think it would be fair to add a respective reference.

Yes, that sounds good to me. Either create an item for that (preferred) or link to the URL directly. On Fri, Mar 13, 2020, 04:06 Osma Suominen <osma.suominen(a)helsinki.fi> wrote:

Thanks for the advice Denny! We've now created two web pages that describe the work we do linking YSO and Wikidata: In English: https://www.kiwi.fi/x/SYO_CQ In Finnish: https://www.kiwi.fi/x/cIK_CQ So following your suggestion, I will now create a Wikidata item for "Project for linking YSO to Wikidata" or something along those lines. The item could then link to the above URLs (using which property?). Then in the actual YSO ID statements (which are many), the newly created WD item would be referred to as the source. Does this make sense or did I get it wrong? -Osma Denny Vrandečić kirjoitti 13.3.2020 klo 16.36:
