[Talk-us] historic schools (amenity=school; name= * (historical)
Hi fellow mappers, While doing some TIGER cleanup, I often stumble over historical schools tagged as: amenity=school name=some small town school (historical) which are rendered on the map with their name. Are there any ideas for a better tagging as most of them (all?) arent really schools any more. I tagged some as historic=school which was in the database 80 times. Any better ideas?

I tagged some as historic=school which was in the database 80 times. Any better ideas? they shouldn't be tagged as amenity=school if they aren't currently used as school, and the name-tag shouldn't contain descriptions like (historical). There are several possibilities to deal with this, probably also depending on the situation (e.g. how long it is that there was an actual school). On way is to use prefixes, e.g. disused:amenity=school or abandoned:amenity=school etc. this is preferable over adding a attribute like disused=yes as the latter would provoke misinterpretations (if you don't search for these status attributes), a risk that is circumvented with the prefix. Another way is to simply tag the building as what it is and don't use any amenity at all, e.g. building=school (= this is a building of the building type school) name=* (should be the name of the building in this case, as name always refers to where it is attached to) etc. you can of course also use historic=school but I would personally prefer one of the two ways described above, the first for not so long closed schools and the second for the rest. cheers, Martin ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

All gnis objects that are (historical) are no longer present and should be removed. - Serge On Tue, Mar 4, 2014 at 5:38 AM, Theodin theo...@posteo.de wrote: Hi fellow mappers, While doing some TIGER cleanup, I often stumble over historical schools tagged as: amenity=school name=some small town school (historical) which are rendered on the map with their name.

Ok Serge,thanks for the encouragement! I have seen schools in the middle of the forrest in a natural park so chances are big there never was a school at that location at all . Ever. :) Thanks, Theodin Am 04.03.2014 15:32, schrieb Serge Wroclawski: On Tue, Mar 4, 2014 at 9:19 AM, Theodin theo...@posteo.de wrote: OK.

To decide you will have to know the area where you are mapping, deducting this from the name tag of an import is most likely not very ground-truthy I agree. cheers, Martin ___ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us

We need to be able to distinguish between the object no longer being present, and the object still being present but its usage having changed. If it is likely to be of historical and/or landmark interest, tagging both the historical name and current name is useful.

Hi all, I think this is a good spot to put this thread to rest. We've answered the question at hand and have since strayed a bit off topic. -Your friendly list moderator On Mar 4, 2014 8:48 AM, Martin Koppenhoefer dieterdre...@gmail.com wrote: 2014-03-04 15:32 GMT+01:00 Serge Wroclawski emac...@gmail.com: We don't store historical information in OSM.
