Discussion
@ChristianKl: I think we should indeed have own properties for important catalogues of composers (like Köchel catalogue (Q162478)) and artists. Kirchner is the most famous Die Brücke (Q152778)-artist and there is only one catalogue about him ever finished.--Kopiersperre (talk) 06:54, 2 October 2016 (UTC)[reply]
What value do you get from having a specific property that wouldn't get from catalog code (P528)? ChristianKl (talk) 10:09, 2 October 2016 (UTC)[reply]
@ChristianKl0: Warum kriegt jede Datenbank mit teilweise geringem Nutzen eine eigene Eigenschaft und ein Werkverzeichnis nicht?--Kopiersperre (talk) 06:35, 3 October 2016 (UTC)[reply]
Google translates that as "Why not get any database with some little use your own property and a business directory?", whch does not appear to answer ChristianKl's question. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:08, 4 October 2016 (UTC)[reply]
Well that's probably Google translate's fault. I would interpret the query as something like "why should even little-used databases get their own property but a catalogue cannot?" but my German is a little spotty. ArthurPSmith (talk) 13:30, 7 October 2016 (UTC)[reply]
Which also does not appear to answer ChristianKl's question. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:17, 7 October 2016 (UTC)[reply]
Little-used databases for which we create properties have formatter urls. A solution like catalog code (P528) doesn't support formatter urls. In this case I don't see any additional use for having a specific property that you wouldn't get from catalog code (P528). If you think there's a use case where having an extra property is valuable please expand on it. It's also useful to treat the catalogs of all artists the same way instead of creating special solutions for specific artists. ChristianKl (talk) 11:45, 15 October 2016 (UTC)[reply]
Apart from question whether this property should be created, it's worth noting that the current proposed type "number" is not compatible with the example's that contain strings. ChristianKl (talk) 11:45, 15 October 2016 (UTC)[reply]

 Not done @Kopiersperre: Use catalog code (P528) and catalog (P972) as qualifier.--Micru (talk) 16:02, 15 December 2016 (UTC)[reply]
