[13:55:13] How come some (all?) properties can be accessed a few different ways? wd:P31 or wdt:P31 or p:P31 ? [14:46:40] anybody? [14:47:10] i guess items use wd: but properties should use wdt: or p: ? [14:51:29] wdt: points from the item directly to the value [14:51:47] p: points to the statement, and from there ps: points to the value, pq: to qualifiers, etc. [14:52:04] see the illustration in https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#Data_model (I hope it’s at least somewhat clear ;) ) [14:52:11] J0llyr0tten: ^ [14:52:24] What would be the right property to link https://www.wikidata.org/wiki/Q20529638 (a churchyard) with https://www.wikidata.org/wiki/Q14955401 (the church irself)? [14:55:26] Jonas_WMDE: https://phabricator.wikimedia.org/T134882 [14:58:26] Similarly for a manor and its associated manor park [16:12:49] reosarevok: honestly, no idea. [16:12:54] heh, ok [16:13:39] Would you say I should ask on https://www.wikidata.org/wiki/Wikidata:Project_chat or https://www.wikidata.org/wiki/Wikidata:Requests_for_comment ? [16:14:11] Well, a churchyard might be part of the church but the church item is mostly focussing on the building and not the whole terrain. [16:14:42] Yeah, I thought of "part of" but I had the same train of thought [16:15:32] For the Netherlands, we also have gates that are marked as national heritage. [16:17:16] Project chat, please. ;) [16:17:38] Ok! [16:17:48] Yeah, for a manor here I have like 15 entries [16:18:21] Including "main building", "storage building", "park", "gate pillars", "cellar" and whatnot [16:18:35] (plus then one entry for every old chair in the manor, of course) [16:18:50] I'm only adding the codes to the ones already in etwiki for now not to go crazy [16:20:05] https://www.wikidata.org/wiki/Q29044875 [16:20:57] Heh, so a separate item, instance of this, with the others as parts? [16:21:16] It seems they don't use P31 for this. https://www.wikidata.org/wiki/Q10431900#P366 [16:21:57] Yeah. But that still doesn't tell me how to link the two in that case :D I'll post and see [16:28:21] Also: we have a surprising amount of holy stones. As in, just a big rock somewhere [16:30:15] Hmm. One case here https://www.wikidata.org/wiki/Q20529910 uses "owned by" for the manor park [16:30:33] Not sure if a building can own stuff... [17:37:58] reosarevok: Your properties were created [17:38:06] And used ;) [17:38:15] (well, a bit) [17:41:46] Added some constraints to https://www.wikidata.org/wiki/Property:P4564 [17:42:12] Should I just remove "church" from p31 here? https://www.wikidata.org/wiki/Q4338470 [17:42:16] It seems kind of redundant [17:43:09] reosarevok: Looks like the intersection problem :P [17:43:25] Which was that? [17:45:17] Do we subclass instance of, or do we use another property? We for humans, we say instance of human, occupation something. [17:45:52] So it could be either instance of Eastern Orthodox church, or instance of church, use Eastern Orthodox church? [17:46:03] In this case I would just remove church [17:46:08] It's properly subclassed [17:46:27] Did then [17:49:43] Oh, multichill, wanted to ask the other day but you weren't around [17:49:55] https://www.wikidata.org/wiki/Q12376420 is in the building https://www.wikidata.org/wiki/Q20530284 [17:50:05] Is "location" correct there? Wasn't sure what to use [17:52:06] reosarevok: Looks correct. See for example https://www.wikidata.org/wiki/Q190804 how it's done here [17:52:24] Ok! [17:52:44] Added occupant. [17:52:50] That seems to be a good property to link back [17:55:49] Thanks [17:57:34] Only downside is that we can't currently construct constraints for this. [17:57:45] Guess we need shape expressions for that. [18:03:03] Complex constraints could work [18:03:13] reosarevok: Talking about complex constraints, added some of them to https://www.wikidata.org/wiki/Property_talk:P4563 [18:03:50] Can you keep an eye on them? [18:20:29] multichill: I can try! Is there a way to get notified if something comes up in them? [18:37:54] reosarevok: Just put the report pages on your watchlist [18:38:24] Oh, ok :) I've never tried the watchlist before, might as well [18:39:48] Can I force them to be created? (I guess otherwise I need to wait until the constraints bot checks it once?) [18:40:35] You can watch uncreated pages. [18:44:06] Oh. How? I only know of the "Watch this page" thing while editing [18:45:05] Oh, duh. The star is for watching [18:45:07] Nevermind :) [18:46:59] so based on my question from a few hours ago, (and the answer given) if i want to use a property i usually use wdt: correct? [18:49:06] J0llyr0tten: In Sparql yes, or p:P123 [19:21:57] multichill: for location, if I only know it's in the collection of the museum, but not in which building is exposed (or if it's exposed at all right now!) what do I do? Leave it blank? [20:25:55] reosarevok: Don't you have an item for the complex of buildings? [20:26:08] Not really, they're all over the city [20:26:26] None other than the main "Estonian Art Museum" one anyway [20:27:23] For the Tartu one, the non-exposed collection is probably in the same building as the museum itself? I could ask [20:27:46] But the other one has multiple buildings and it seems the digital info doesn't specify where the piece is [20:32:01] In these cases I usually just set the collection as location [20:32:16] So just the item for the main museum itself? [20:32:52] Yeah, people can always split it out to more specific locations [20:33:28] Ok! [20:33:31] That sounds doable [20:50:40] SMalyshev, is there an easy way to disable wdqs custom whitelist for the custom installation? [20:57:35] SMalyshev, also, is there an easy way to connect to a CSV data source as a federated source? E.g. service url would be a CSV data dump, and the SERVICE { params } would extract all the data into the query
