  • Pictogram voting comment.svg Comment When investigating how to scrape this website, I noticed that the IDs are identical to the RKDartists ID (P650) ones. Fotografen.nl is a subset of the RKDartist photographers only - approx. 35,000 photographers from the Netherlands or with some kind of relationship to the Netherlands (once exhibited there, for instance). Not all persons with RKDartists ID (P650) have an official (indexed) entry in fotografen.nl; and fotografen.nl offers additional information in some cases (some written biographies, information where archives are held...). So I think it does definitely warrant its own property. Spinster 💬 08:01, 27 August 2016 (UTC)
    • So what IDs to people only in fotografen.nl have? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:34, 28 August 2016 (UTC)
      • @Pigsonthewing: There are no people only in fotografen.nl. All people in fotografen.nl have an ID in RKDartists as well. (Not vice versa.) Spinster 💬 10:32, 29 August 2016 (UTC)
        • In that case, Symbol oppose vote.svg Oppose. Add a second formatter URL to RKDartists ID (P650), marking the original FURL as preferred. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:19, 2 September 2016 (UTC)
          • I disagree. Not all people in RKDartists are indexed and enhanced on fotografen.nl; only a small number. Fotografen.nl only contains photographers, with additional metadata about them (biographies, bibliography, information where their archives are held) which is only available on fotografen.nl for those specific photographers. Having a separate property on Wikidata for this would allow querying specifically for these people and then clicking on to find this specific metadata - pretty useful for any researcher or editor specifically interested in photographers and photography. So I keep pleading for a separate identifier. Spinster 💬 15:21, 2 September 2016 (UTC)
          • (This is when you'd use a boolean to indicate whether this URL is valid too for the already recorded ID instead of recording it twice. – Máté (talk) 21:01, 3 September 2016 (UTC))
            • Do we already do this for other properties? If so, what does this look like? How would you query this? If a researcher of, for instance, photography, would like to query all Wikidata items with external identifiers in photographers' databases, how would that query look like if fotografen.nl is treated differently than, say, Photographers' Identities Catalog ID (P2750)?

              • No, I don't think we've done this. What we have done, is creating sub-properites of external IDs (like EIDR identifier (P2704) of DOI (P356)). I checked and those who (I suppose) know more about these things did argue, that modelling external IDs in a different way than with the external ID datatype causes too much complexity, and storing the ID twice is still preferable to a pseudo-boolean qualifier that I mentioned. – Máté (talk) 19:34, 4 September 2016 (UTC)
