Buildings

We (OSM Ireland) always use them for buildings, as far as I am aware, but with a combination of building=church/ building=mosque + amenity=place_of_worship. I wasn't aware that that was wrong and I don't see the logic behind it, when we double-tag schools (building=school + amenity=school) and pubs (building=* + amenity=pub), for example. After all, the buildings are the places where most worshipers go most of the time. B-unicycling (talk) 17:51, 16 April 2021 (UTC)

So when I created the page, I was just going off current convention based on the amenity=place of worship page and usage stats (place of worship=church has tiny amounts of usage for example). I would note that your examples match with the current way of mapping, i.e. amenity and then building type, so amenity=place of worship, building=church is analogous to amenity=school, building=school. To add another tag to say the same thing seems superfluous? I don't really have an opinion one way or another though - so might be worth raising on the tagging mailing list to see if there's a consensus? We can then of course change the wiki based on that.

For two reasons it is not superfluous: A church or school building can have been revamped to be used as a house or restaurant or library or whatever, likewise a barn or an apartment could be used as a place of worship by a smaller community. B-unicycling (talk) 20:23, 16 April 2021 (UTC)
But that's why there's building:use=* right? To show when the current use is separate from the building type. Like I say, I'm really not fussed. But using this tag as you suggest is very much the minority (73,998 building=chapel but only 890 place_of_worship=chapel - almost all of which are located in Austria).

Just had a look, this tag is only used six times in Ireland currently. So it really can't be "always" used. http://taginfo.openstreetmap.ie/keys/place_of_worship#values Casey boy (talk) 20:43, 16 April 2021 (UTC)
Maybe we're not talking about the same thing here. I wasn't suggesting place_of_amenity=church, but your definition says not to use place_of_worship=* on buildings, which I find confusing.B-unicycling (talk) 21:10, 16 April 2021 (UTC)
As far as I cant tell, this key (place_of_worship=*) is rarely used and even more rarely in Ireland (which is what confuses me when you say "OSM Ireland always use them", it's been used six times...). Globally, place_of_worship=* has been used in conjunction with building=* only 1,604 times. The current documented tagging scheme says instead to use amenity=place_of_worship and building=*. This practice is used 694,065 times globally. Therefore it seems amenity=place_of_worship and building=* is much preferred over using place_of_worship=* for a building (e.g. a church, chapel, or mosque). If that makes sense, and you agree, then I'll try and make it clearer on the page. Casey boy (talk) 09:45, 19 April 2021 (UTC)
We must be talking about two completely different things here, no way are there only 6 uses of place of worship in Ireland, when there are at least 117 holy wells mapped, let alone the hundreds of churches. Could you please give your overpass query that left you with 6 occurrences of place of worship in Ireland?B-unicycling (talk) 11:01, 19 April 2021 (UTC)
I get you now, you want/ are talking about place_of_worship=church, whereas we have used amenity=place_of_worship + building=church so far (for buildings). It would indeed make sense to have it more standardised. B-unicycling (talk) 11:38, 19 April 2021 (UTC)
Yep, this page is for using "place of worship" as a key, not a value.Casey boy (talk) 13:33, 19 April 2021 (UTC)
OK. So I was using Ireland's taginfo page: https://taginfo.openstreetmap.ie/keys/?key=place_of_worship#overview but it seems that this information is out of date. An overpass turbo query shows a total of 188 uses in Ireland (https://overpass-turbo.eu/s/16lK) - so plenty more, though not quite "117 holy wells mapped [and] let alone the hundreds of churches". I don't know how many are buildings though (seeing as I was using taginfo to get that information). Casey boy (talk) 11:26, 19 April 2021 (UTC)
After discussions on the tagging mailing list, I've removed the "not on buildings" text from this page. It seems as though, although not (currently) widely used or approved (yet), this key could be useful to further define the place of worship, especially when the building type does not match the amenity type (e.g. a church inside a warehouse building).
