The Blind Leading the Blind (Q1192570) is a painting that has two properties that contain identical information: depicts Iconclass notation (P1257) 31A41111 as well as depicts (P180) the blind leading the blind (Q1565024). Because the blind leading the blind (Q1565024) already has the property Iconclass notation (P1256) 31A41111, there's no additional informational value gained from having both depicts Iconclass notation (P1257) and depicts (P180) for this painting. I know there are many places now where we don't have a clear Iconclass 1-to-1 mapping with Wikidata and so it's useful to have both properties. But when we do have a Wikidata entity for all Iconclasses, we should deprecate the Iconclass properties and just use depicts (P180). Runner1928 (talk) 16:23, 22 October 2015 (UTC)
- This was addressed at WD:Property proposal/Archive/21#P1257. And I'd be overhappy if we replaced the Iconclass system which is anything but perfect IMHO. Though they state that they have 28,000 definitions which is a nice bunch to create!
- Commons often has a more finely graduated classification of iconography in its categories. I good begin might be do create items for the useful categories, add Iconclass notation (P1256) to them and make up the classification here with subclass of (P279) probably and to make up templates on Commons that retrieve and display the Iconclass notation. --Marsupium (talk) 13:00, 24 January 2016 (UTC)
