[1] https://wiki.openstreetmap.org/wiki/Key:contact:webcam This isn't perfectly what you referred to, but let me try to explain my interpretation of this and why it excludes for example the discussed contact:webcam: For this example, contact:webcam is ambiguous: it may be the webcam operating team inside the operating company or whatever, or it may be the imagery of the webcam. But if it's the latter (which I personally don't agree), then we could extend contact by other stuff, too: A shop with a product catalogue availlable online in a machine readable form could get contact:productlist=....xml An installation that can be remote-controlled could get contact:remotecontrol=* I think, contact should be restricted to ways of getting in contact to someone, and IMHO seeing images of a webcam is not getting in contact to the webcam or "someone" else. regards Peter > > As I have stated before, I do not care too much about what the key is, > as long as it is documented. > > As for now, I think contact:webcam is best because of previous work: > - it is already in https://wiki.openstreetmap.org/wiki/Key:contact > - it is proposed in > https://wiki.openstreetmap.org/wiki/Proposed_features/Extended_tags_for_Key:Surveillance > > - it is actually used, although no much > > Inconsistent usage, dead links for contact=webcam is IMHO not a valid > argument against its use.
