[00:42:54] <Dragonfly6-7>	 is there any way to find out how many editors have added a particular value to a particular field in any entry? (based on the edit summaries)
[00:46:03] <Dragonfly6-7>	 specifically I'm wondering how many editors - human or bot - have made this edit:
[00:46:06] <Dragonfly6-7>	  ‎Created claim: has works in the collection (P6379): Führermuseum (Q475667)
[00:46:13] <Dragonfly6-7>	 is there a way to find that.
[07:37:49] <Lozenge>	 koi: done
[21:47:20] <Dragonfly6-7>	 is it possible to block a given field from having a given value? a) yes, b) no, c) the question as phrased is not meaningful.
[21:51:44] <bd808>	 Dragonfly6-7: https://www.wikidata.org/wiki/Help:Property_constraints_portal might be hints towards what you are asking
[21:52:08] <Dragonfly6-7>	 thank you.
