Unique value

Latest comment: 5 years ago13 comments7 people in discussion

I'm not sure the Unique value constraints is applicable in this case. There is nothing preventing two objects from using the the same coat of arms image. As an example we could have two successive kings both using the state coat of arms or a municipal coat of arms being the same as that of the original city. /Lokal Profil (talk) 10:18, 9 September 2013 (UTC)Reply

Hi @Lokal Profil, Ivan A. Krestinin, Docu: not sure Unique value constraint is a good idea. Members of the same familly or territories with shared history could have the same blazon (very common for commune of France (Q484170)) ; if we keep this constraint there will be a huge amont of exceptions.
For instance on Saint-Didier (Q963301) I just add coat of arms image (P94) : File:Héraldique - fretté.svg. Should I add it as an exception on Wikidata? Should I duplicate the file on Commons? (which is a bad pratice but not uncommon).
Cdlt, VIGNERON (talk) 18:12, 14 July 2015 (UTC)Reply
I would remove the unique value constraint. Is it instead possible to blacklist values (such as Sin escudo.svg)? /Lokal Profil (talk) 19:20, 14 July 2015 (UTC)Reply
Exceptions for unique value are present of course. The question is how many exceptions we have in real data. Also you mention some cases, lets discuss one case: members of some family have shared coat of arm. There are two ways to model this case:
  1. We add this image to every human (Q5) item.
  2. We create special lineage (Q1642895) item and add coat of arm image to this item only. human (Q5) items are linked with lineage (Q1642895) using family (P53).
The second way is better describes reality as I see, but it has some limitations too. — Ivan A. Krestinin (talk) 20:04, 14 July 2015 (UTC)Reply
I've added human (Q5) since there are also some coat of arms for individuals (e.g. unique CoAs for members of royal families) for this reason I wouldn't restrict CoA use to only lineage (Q1642895).
In general I think it might be worth creating Qitems for the CoAs themselves then connect these to lineage (Q1642895) (and/or human (Q5)) using coat of arms (P237). This allows other statements (such as coat of arms image (P94), blazon, history etc) to be given in one place without unduly cluttering the lineage (Q1642895)/human (Q5) item. /Lokal Profil (talk) 15:02, 15 July 2015 (UTC)Reply
Per Wikidata:Project_chat#New_Constraint_.3F filenames such as sin escudo.svg could be blacklisted using a second {{Constraint:Format}} instead. Sadly I'm not enough of a regexp ninja to make that work. /Lokal Profil (talk) 15:26, 16 July 2015 (UTC)Reply


Great discussion (I was away for some time, sorry I missed your comment).
Ivan A. Krestinin : lineage (Q1642895) could have been a good idea but it's not since the reality is far more complex. Members of the same familly could have the same coat of arms but not always. Different famillies can have the same coat of arms too. Plus, it's not unusual for a coat of arms to be shared between a familly and a territories. In ecclesiastical heraldry, coat of arms can be shared between people (not in the same familly obviously) and/or places (an abbey and its abbots for example; but high rank people like popes or bishops have usually their own coat of arms). Simple coat of arms like « Azure a cross argent » are very common and shared by unrelated places and people (qv. commons:Category:Azure a cross argent for examples), sometimes the files are duplicated with different names on Wikimedia Commons but sometimes the same simple file is used for differents articles/items.
Right now there is only 1967 contraint violations but there is only 52115 uses of P94.
Lokal Profil : the Project chat discussion doesn't seems to give a way to forbid placeholder. A regex is nearly impossible since the placeholders have too differents names. I'm maybe wrong but I thought it was impossible to use two Constraint:Format on the same page (I think I remember something like « only the last one will be consider »). Maybe we can use an extern tools for that? (Autolist??)
Cdlt, VIGNERON (talk) 12:38, 29 July 2015 (UTC)Reply
@VIGNERON:. The project chat (now archived) suggests that you can use two Constraint:Format. You are probably right about the regexp though. Other than having a long list of strings to compare to I think it might be hard. Ideally with CommonsData we could tag such files as placeholder and then do something fancy but that is still some time away. /Lokal Profil (talk) 10:34, 4 August 2015 (UTC)Reply
Please delete the unique value constraint. I edited dozens of items of persons, members of the same family, that used the same coat-of-arms. Everywhere I get a violation message. Can't say I get happy from those messages. HRvO (talk) 20:45, 18 August 2018 (UTC)Reply

Still the same problem, about which evidently nobody has cared enough since 2013. Good to see some things in life are still reliable. In this case, a modern city (Tartu City, Q42307965) uses the same coat of arms as did the medieval Bishopric of Dorpat (Q389360). There's nothing to prevent them IRL but hey, what do we care in WD? It's not like constraints have to make sense, right? --Ehitaja (talk) 23:21, 19 January 2019 (UTC)Reply

I went ahead and removed the unique value constraint. The main successful use case that this constraint used too reveal - "no coat of arms" placeholder images - are now handled by RegEx "format" constraints. It seems that most people here agree that it is counterproductive in general to throw warnings at multiple items having the same coat of arms, when in real life it is common for related people and groups to share the same coat of arms, and sometimes even for unrelated groups to happen to use exactly the same coat of arms.
