Untitled

This is the kind of property we ought to have anyway, to express relations between items and a particular set of wiki pages, in the same way that we now have Commons Creator page (P1472) for the Creator namespace. Jheald (talk) 16:39, 20 September 2014 (UTC)

Validation

Can we add a check for the prefix "Institution:" and throw a warning if one is found? (Better still: automatically remove it?) Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 09:44, 13 February 2015 (UTC)

@Pigsonthewing: the format constraint does exactly that and it's set to mandatory. Multichill (talk) 19:17, 13 February 2015 (UTC)

Thanks, but nonetheless I was allowed to save such a value, with no notification. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 22:19, 13 February 2015 (UTC)

You could make an abusefilter, but I'm afraid that's not going to be very user friendly at all. Multichill (talk) 12:10, 14 February 2015 (UTC)

My bot fixes "Institution:" prefix and some other unwanted values. — Ivan A. Krestinin (talk) 15:29, 14 February 2015 (UTC)

Awesome! Is this documented somewhere? Would be nice to have it on this page or link from this page. Multichill (talk) 17:49, 14 February 2015 (UTC)

It is mentioned on bot`s page. Bot process all Commons-related properties. The job was started at summer 2013. — Ivan A. Krestinin (talk) 18:14, 14 February 2015 (UTC)
