There does not appear to be any suitable property to represent the number of a room, as a property of a room (Q180516). In large institutions like universities and museums it is common for every room to be identified by a number, that is unique within the institution. I recommend using a string, because at universities "room numbers" often contain letters identifying the building or place. I would expect this property to be an instance of Wikidata property for places (Q19829914), subclass of Wikidata property to indicate a location (Q18615777).

  • Symbol support vote.svg Support I like this as proposed including the string element (at my institution everything is "Building LetterNumber", and there are dozens of G15s...). I would suggest having "room name" and "room identifier" as aliases - there are probably cases where the rooms are officially identified only by names, and it would be good to handle these consistently rather than having to guess at using the label.

    • I agree with having "room identifier" as an alias but I disagree about "room name" because it could lead to non-identifying names being accidentally claimed as identifiers. --Gittenburg (talk) 15:32, 2 November 2019 (UTC)

    • Why "room number" over "room identifier" if the property is also supposed to house idenftifiers that aren't numbers? ChristianKl❫ 08:26, 4 November 2019 (UTC)
