Generalizing this propertyEdit

As per discussions about the need of a property to indicate the number of parts in a system, it has been suggested to generalize this property. The suggested label is "number of elements". If there are no objections I will change the label in a couple of days. See Wikidata:Property_proposal/Generic#number_of_parts.--Micru (talk) 07:25, 10 July 2014 (UTC)

I support the generalization (actually I thought the property could and was already used for that) but I am not sure "element" is very clear. It seem that train X number of elements five could be used to mean that the train is made of 5 carriages. I have no better suggestion for a label though. --Zolo (talk) 08:54, 10 July 2014 (UTC)
@Zolo: That is not a problem because you can use qualifiers, for instance: <train> has part <carriage> with qualifier number of elements <5>. If you just say <train> number of elements <5>, it means that there are 5 trains.--Micru (talk) 09:18, 10 July 2014 (UTC)
@Micru:. I understand it is what is intended, but I am not sure that the word "element" makes it perfectly clear. "number of element of train X" seems to mean how many parts there are in a typical train X not how many instances of train X there are. . --Zolo (talk) 09:28, 10 July 2014 (UTC)
@Zolo: If you have any other suggestion I'll be glad to hear it. It could also be just "quantity" (in German it is already called "Anzahl", and we have it as alias now).--Micru (talk) 09:41, 10 July 2014 (UTC)
@Micru: Yes, perhaps simply "quantity" or even "number" as quantity might imply a measurement unit. --Zolo (talk) 09:53, 10 July 2014 (UTC)
I agree that dropping "of elements" is best. Like Zolo, I think "number" or "quantity" would be better, with the former being slightly better than the latter. Micru, thanks for taking the initiative on this! Emw (talk) 12:53, 15 July 2014 (UTC)
I've changed it to "quantity" because "number" is too ambiguous. The statement "number: 5" can be interpreted as this is the fifth of someting. /ℇsquilo 16:13, 8 September 2014 (UTC)
Good point, thanks. Emw (talk) 03:09, 11 September 2014 (UTC)
