    Logo on WikipediasEdit

    Are we not suppose to put the interwiki links of the non-free files on WD? If it is allowed, do we need a new items type property for logos like Q11213018 (logo of Q192452)--L!tt|e+ung?\2o/3=] 02:52, 26 April 2013 (UTC)

    Logo as ItemEdit

    Is there already a way (another property) to set items as values for "logo"? For example Linux (Q388) could set the item Tux (Q131200) as Logo too, instead of only a file on Commons. At least this problem isn't new, but maybe I've misses something.
    Best regards, --#Reaper (talk) 12:40, 23 December 2014 (UTC) (Please ping me on answers.)

    • @Reaper35: Multitype properties are not supported now. So separate property is needed. You can suggest it on WD:PP. But are you sure that we have notable count articles about logos? — Ivan A. Krestinin (talk) 19:21, 23 December 2014 (UTC)
      @Ivan A. Krestinin: Well, thats an useful point. I noticed now also, that Tux isn't a logo but an mascot character (Q386208) (Or maybe both?), so it would not fit here at all. And for this there is already an property: mascot (P822). (So I added this to Linux.)
      Currently there are only 3 items linking to logo (Q1886349), the categories on enwp have some more. But indeed, maybe not needed yet. (And maybe there will be an better solution instead of a second property in future.)
      Thank you and best regards, --#Reaper (talk) 23:30, 23 December 2014 (UTC)

    Constraint:Type with class Q43229 (Organisation)Edit

    Above there is set a Constraint:Type with the class organization (Q43229). It says that logo image (P154) can or should only be used when the item is an instance of organization (Q43229) (or an subclass of this). But at least that is wrong. Also software, products, websites, sport clubs or whatever can have an logo. So we should remove that constraint completely, as I think it's not possible or not useful to catch all variations.
    Best regards, --#Reaper (talk) 12:48, 23 December 2014 (UTC) (Please ping me an answers.)

    Agreed. I removed constraint on type "organization (Q43229), product (Q2424752), trademark (Q167270)", 80% violations according to the last violations report considering it. -- LaddΩ chat ;) 15:08, 20 December 2015 (UTC)

    Unique value constraintEdit

    I don't think this property should have a unique value constraint. If you look at the violations you can see that the same logo can be used by multiple entities, for example subsidiaries or successor organizations. I suggest to remove this constraint. --Srittau (talk) 02:52, 31 December 2015 (UTC)

    OK with me. -- LaddΩ chat ;) 16:35, 31 December 2015 (UTC)
      Done --MB-one (talk) 14:26, 13 April 2019 (UTC)

    png or svg for Wikimedia sites?Edit

    We have consensus on official website (P856) that must be https://(code).(wikiproject).org/, but how about logos? I can't see any consensus here. --Liuxinyu970226 (talk) 04:05, 3 July 2017 (UTC)

    Property to know wether the logo include the name or notEdit

    Some logos include the name of the trademark, other not. It would be nice to have a property to tell whether or not the logo includes this text. What do you think? Romain2boss (talk) 22:25, 14 February 2018 (UTC)

    @Romain2boss: For what propose? Copyvio checker? --Liuxinyu970226 (talk) 02:31, 30 June 2018 (UTC)

    Allowed qualifiers constraintEdit

    In an effort to add a little bit of order and consistency, I've added a allowed qualifiers constraint (Q21510851) to this property. I've included every property I can think of that makes sense to use with this, but it's likely I missed some (the SPARQL query to view violations of this constraint times out, even with LIMIT 100). I haven't made it a mandatory constraint (Q21502408), though perhaps that should eventually be done once the list of allowed qualifiers is nailed down. –IagoQnsi (talk) 21:25, 17 August 2020 (UTC)
