Dear all,
sorry for my long silence, but I was away.
I seems that my opinion are minoritarian, but still I want make one last try to
explain things clearly and then I will shut up on this subject.
1. Why is "man_made" bad
*****************************
It's a very unclear category anyway.
If you have an historic interest, than you may find out that it was originally
thought to map outstanding features in mainly natural environment - so from
that perspective - man_made maybe makes sense for a "break-water" on a else
natural cost, or an "adit" in a mountain region.
=> but never I seems logical to anybody to tag a CCT-cam in a restaurant with
the tag "man_made".

+1 for cleaning up "man_made"!!!
2. Why surveillance cannot be the main tag, but it must be camera
******************************
"Camera" is what it is.
"Surveillance" is what you do - sometimes - with it.
You will not call a "car" "driver", because you drive with it. And then, call a
bike "driver=rider", because you ride the bike, and you have to use the same
tag because a car and a bike have both wheels ...

NON. The webcams we are talking about are not surveillance cams.
The intent of a device IS important. Not every camera is placed there in the
intent you do surveillance. Webcams are generally placed exactly in a way NOT
to show any persons (often also they are forced to do so by law).
You can argue that they do surveillance of the mountain they are showing, but
believe me, the mountains very rarely move and do absolutely not care if they
are watched by a ant or not.
I do not call a building having a coffee machine in it a "cafe", but I only
call it this if I actually can go there and drink a coffee.
I completely agree on the importance of tagging "Surveillance cams". (I just
mapped several pubs in my city with man_made=surveillance because they added
surveillance cams, and I want people to stop going there). Civil rights are
important, and I completely agree on fighting for them. But let's stop being
ideologic and see only this.

I do not think in the OSM context it matters what kind of technology is used.
But we map identifiable features. Is there a camera, that I can see or that I
can know that is there? => so it's a camera.
Is the camera a surveillance camera to watch people? => so it's surveillance.
Is it a camera that shows a picture of the scenery, of a mountain, of the
weather and normally not people? => so it's a webcam. (a camera to inform
people about weather and snow conditions, normally viewable on the world wide
web, that's what the name comes from. So a internet connected surveillance cam
does clearly not qualify for this.).
3. Making tagging locial or keep it as it was to make life simple for renderer?
*******************
* completely agree on not changing tags too often.
* But a renderer is much easier to adapt to new rules than the mind of
thousands of mappers (especially if OSM is interested to have new people join
in).
* Unlogical tagging leads to more of
** not mapping at all => this is what seems to happen with webcams, and is
the primary reason why Egil started this whole discussion.
** people mapping how the like and so we get different mappings for the
same thing => this is a nightmare, and more difficult to handle for renders
than a well documented tagging change followed by a properly done mechanical
edit.

Ok, so let's define at least a "future architecture", and let's move to it step
by step each time we work on a tag.
4. The initial idea was: give people a tag to properly tag webcams

So don't do it if you think it's wrong.

It is never too late. This can be changed.

I completely understand. But I think it's important that OSM does not get a
closed project which stays at it has always been. If historic tagging is
difficult to grasp for newcomers, we should think about to adapt it.
AND more importantly, you started this whole discussion to get webcams mapped.
We tagging you actually suggest, THIS WILL NOT BE DONE. Because people
interested in webcams are often (take me as a counterexample but...) different
people than the ones interested in mapping surveillance cams. And the will not
like this what will seem a completely absurd tagging and they will not use it!
So you will not gain anything.

Sorry, this is nonsense. You're really giving up on your initial idea. And
maybe it was stupid me you started the whole idea that a camera is camera. I
apologize!!!
But you can not really ask somebody to tag a webcam taking a picture of a
mountain to tag:
man_made=surveillance
surveillance=outdoor
surveilance:type=camera
surveillance:zone=weather;clouds;scenic;snow
contact:webcam=http://watchmehere.org
Nobody will understand this, nobody will tag this, and will vote against this.
5. The URL to the image

"contact:webcam=http:/...." ???? Do you really think this to be clear? Why so
complicated? Do you really want to rely on a proposal made FIVE years ago and
never accepted???? Key:Surveillance

maybe better, but still much too complicated!
According to http://wiki.openstreetmap.org/wiki/Map_Features, there is a
established tag to give the webadresse connected to node
website=*
the tag "URL" is outdated. Why come back to this?
What is wrong using website=*? I agree there might be a confusion if you give
the webadresse of the camera-provider or the image itself, but this can easily
cleared up by documentation, and it does not really be interesting to give both
address, the image URL normally being a sub-adress of the the operators
website. And thinking about the man use of the webcam (a map with all webcams a
can click and view the image), it seems very straightforward to tag the actual
image address.
Therefore, I reiterate my suggestion:
camera=surveillance | webcam | trafficcam | ...
website=...
Since it seems that all surveillance cameras actually mapped are done so
properly, so I do not see any obstacle to make a proper mechanical edit if the
proposal of the new tagging and the proposal for the mechanical edit are
accepted.
Or, if really people want to keep man_made=surveillance for nostalgic reasons,
we should split up again and make:
camera=webcam | trafficcam | ...
website=...
and leave surveillance in peace ...
If there is anybody out there thinking like me, please stand up. If not, I will
stop arguing and shut up.
Have a nice day,
Nounours.
