Motivation

With this museums and the general public can check of a wikidata-item if the copyright of an artist is handled by a collective rights management organisation in the UK. As DACS is also tracking artists worldwide we can verify the values with other national collective rights management organisations Hannolans (talk) 06:41, 12 April 2017 (UTC)

Discussion

• Is the DACS number stable? There was a DACS catalogue on Mix'n'Match that had a lot of matches that became useless because the numbers all changed. Jheald (talk) 12:58, 17 April 2017 (UTC)
  • Good question and was not aware of the mix n match issue. They call it 'ArtistId' in the URL so I assume this is a stable id. If it is not stable, at least we have the members mapped, and can remap them if they change the ids or link to the Internat Archive--Hannolans (talk) 19:07, 17 April 2017 (UTC)
    • @Jheald: which set? Any links? Maybe someone can contact them to check this? Multichill (talk) 19:01, 20 April 2017 (UTC)
      • @Multichill, Hannolans: It was the "Picto-DACS" catalogue on Mix'n'match. Here's the thread where I notified the issue to Magnus, which will give the rough date that the previously matched values ceased to work. Jheald (talk) 19:32, 20 April 2017 (UTC)
      • * Those ids were not the DACS-ids but data with DACS and PictoRight names in it from Sweden if I'm right. We now have better sources and a tool to match those names to the ids. --Hannolans (talk) 15:35, 21 April 2017 (UTC)
        • Well Mix'n'match resolved the numerical ID all right to a page with the artist's name on the DACS website... the trouble was that after a few months the same number resolved to a different artist's name there. Jheald (talk) 19:25, 25 April 2017 (UTC)
          • Good catch. All pages were indexed by Internet Archive. Compare artistid 71710:
• https://web.archive.org/web/20151231211607/http://www.dacs.org.uk/licensing-works/artist-search/artist-details.aspx?ArtistId=71710
• http://www.dacs.org.uk/licensing-works/artist-search/artist-details.aspx?ArtistId=71710

while the website look similar, the artists are different. --Hannolans (talk) 21:37, 25 April 2017 (UTC)

• • I'm very curious about this, did they upgrade the database system, or is this system altering the ids once in a while?--Hannolans (talk) 13:37, 26 April 2017 (UTC)
