[08:56:45] <eeeeeeehu>	 hello, I just had an idea for something... but apparently "classes" don't point to their "instances"? I.e. "Country" is member of the european union but european union has inverted relation to "country"?
[08:56:54] <eeeeeeehu>	 *has no
[08:57:02] <eeeeeeehu>	 did I miss something?
[09:04:42] <eeeeeeehu>	 Oh found it...
[09:05:40] <eeeeeeehu>	 ok... I guess that structure makes sense...
[09:40:02] <sjoerddebruin>	 Is there something that indicates that a building was only planned and never build?
[09:45:11] <Alphos>	 sjoerddebruin i think you just had an idea of a new taxonomy in wikidata
[09:45:25] <sjoerddebruin>	 probably have to create a item yeah
[09:45:29] <Alphos>	 alongside "fictional *", we could have "planned *"
[09:45:34] <sjoerddebruin>	 we have items for former buildings, but this was never build
[09:46:07] <sjoerddebruin>	 we have things as https://www.wikidata.org/wiki/Q16214696 tho
[09:46:12] <Alphos>	 quite possibly with a new property too
[09:46:23] <Alphos>	 "date the plan was abandonned"
[09:47:23] <Alphos>	 by the way, why on earth is "ship project" a subclass of "ship class" ? oO
[09:47:41] <sjoerddebruin>	 I added project now
[09:48:10] <sjoerddebruin>	 Hm, "Proposed or planned buildings and structures"... what would you choose as main English label?
[09:51:20] <sjoerddebruin>	 hm, enwiki chooses proposed
[09:51:37] <sjoerddebruin>	 https://www.wikidata.org/wiki/Q25935444
[09:52:09] <johtso>	 What the correct approach to adding this wind turbine? https://www.wikidata.org/wiki/Q25935430
[09:52:24] <johtso>	 Should I create a wikidata item for the model of wind turbine, and make it an instance of that?
[09:52:38] <sjoerddebruin>	 probably yeah
[09:52:42] <johtso>	 or do I add the manufacturer and model number to this item?
[09:52:47] <johtso>	 or both?
[09:55:36] <johtso>	 is there a "model" statement?
[10:06:48] * d3r1ck checks in
[10:07:57] <johtso>	 I'm surprised there's not "product code" or "model number" property
[10:08:17] <d3r1ck>	 Hi everyone :)
[10:08:20] <johtso>	 seeing as "serial number" explicitly mentions them as concepts.. https://www.wikidata.org/wiki/Property:P2598
[10:08:20] <stashbot>	 P2598 (An Untitled Masterwork) - https://phabricator.wikimedia.org/P2598
[10:08:47] <johtso>	 should I open a property proposal? or have I missed something?
[10:17:25] <johtso>	 And if so, what category would the proposal go in?
[10:26:29] * physikerwelt hi, I'm going to give a talk on "math support for wikidata" next week. Regarding this I have two questsion. 1. Is there a help page on this topic or is https://www.wikidata.org/wiki/Wikidata:WikiProject_Mathematics the best place to link to? 2. Can I query for the data type in SPARQL to see how many math expressions have been created?
[11:25:31] <johtso>	 physikerwelt: what kind of items did you want to count?
[11:30:58] <johtso>	 physikerwelt: here are all theorems http://tinyurl.com/gshye7w
[11:45:39] <physikerwelt>	 johtso: thank you. Thats a nice list. Can I also figure out how many have the property defining formula
[11:46:59] <johtso>	 that's a good question, I'm not sure how you'd write that query...
[11:47:18] <johtso>	 nikki ?
[11:59:31] <tseppelt>	 physikerwelt: johtso: 16. please have a look http://tinyurl.com/jfyw78y
[12:01:21] <physikerwelt>	 tseppelt: thank you. 16/1987 theorems have a defining formula
[12:03:46] <physikerwelt>	 which reminds me of T137784
[12:03:46] <stashbot>	 T137784: Wikidata label service should render math - https://phabricator.wikimedia.org/T137784
[12:21:21] <tseppelt>	 physikerwelt: Yes, that would be nice.
[12:27:21] * physikerwelt tseppelt: I guess that should not be super hard if one knows where the code is located
[12:28:20] <tseppelt>	 physikerwelt: I can imagine many issues but I don't know anything about the code so it wouldn't make sense to worry ;-)
[13:00:47] <DanielK_WMDE_>	 Lydia_WMDE: https://phabricator.wikimedia.org/T140891
[13:53:13] <physikerwelt>	 DanielK_WMDE_: ping
[14:52:24] * physikerwelt can someone have a really quick look at T137784 please?
