Hi,
I'm not happy with contact:webcam, as the contact namespace IMHO serves
a different purpose.
contact:webcam could define whom to contact for questions regarding the
webcam, or whom to contact BY webcam (as contact:phone is for how to
contact e.g. a shop by phone).
1) I would change the order, as it's part of the webcam information, not
part of the contact information, which would lead to webcam:*
2) I would use url instead of contact, if it should refer to where the
webcams output can be seen, whcih would lead to webcam:url=*

Check https://wiki.openstreetmap.org/wiki/Key:contact
Yes, it's defined there, but that doesn't make it a good solution.
It's used 180 times worldwide according to taginfo.
A check through first 50 values listed in taginfo [1] reveals:
1) all of them are website urls
2) most of the URLs are dead or wrong
3) the valid ones are mixed: some refer to the image, some to a website
containing the image, some probably even to a fixed image (not updated),
but I couldn't check that properly.
4) 80 values are from the same domain and refer to cameras of the same
operator or organization:
http://www1.eot.state.ma.us/cam_updated_images/*.jpg
To conclude this I would say:
The tag is not yet used much (especially due to (4)).
It is not used in a unified way (see (3))
Therefore it's not useable in the current form.
And as it doesn't fit semantically (it's not a URL to contact someone,
but to see something), I don't see a big issue in "fixing" that by
moving the tag to another key and to define it better.
regards
Peter

Do you have any reference to back up your claim that contact:*= is
intended only to provide contact info for reaching humans?
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. It is just a consequence of poor
documentation, so we do not get the full power of crowd sourcing.

Egil
