So does the road network :P Put it in OSM if: 1) it refers to a specific latitude and longitude 2) it's a verifiable fact 3) you want to Whether or not it's likely to go out of date quickly is not relevant - it just means we need more mappers... > 2) Assuming yes, how to denote the detail: > > For instance, tanning=yes, does that mean a spa provides tanning services or > is it related to a factory that tans leather? Well...before you decide to use tanning=yes, check if it's already used (tagwatch, wiki, etc.). If not, go ahead and use it - and document your use of it on the wiki. If someone comes along later to tag a factory, they'll need to choose their tag carefully, and update the documentation accordingly. Basically - for tag definitions, rely on the wiki. > With all that said, going the route of: > shop=beauty > beauty=tanning > beauty=massage > etc. The problem is that you can only have one value per key, i.e. you could only have beauty=tanning OR beauty=massage. An alternative is to use something like a "namespace" concept. Have a look at how to tag amenity=parking's: http://wiki.openstreetmap.org/wiki/Parking. Notice the tags capacity:disabled=*, capacity:parent=*, etc. If you want to use this kind of scheme for the beauty example, I guess you could probably use: shop=beauty beauty:tanning=yes beauty:massage=yes etc. But this probably isn't necessary in this case. I'd be happy either way, as long as it's documented on the wiki... :) _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
