Maxspeed is not a speed to time routes but a legal information. By not mentioning a lower speed than normal, the information is incomplete and liable to be called dangerous in some places where wet speed is justified. Even more so for :snow and/or :ice maxspeed. Speed to predict journey duration can be based on data recorded by some GPS manufacturers on some GPS devices of their customers. It can be very complicated, using location and time. The simplest tag would be speed:average. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

It doesn't make any sense IMHO to deprecate something like highway=bus_stop if 90% of all bus stops are tagged like this (and btw. the public_transport platform version has mostly disadvantages, needs more tags to end up with the same meaning). cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Status of maxspeed:wet
Before we use some strong words lets take a look at the issue: according to taginfo maxspeed:wet is used 602 times. You may subtract one or two hundred as I added them. So we are talking about a tag that's currently used less than 500 times and without a known (at least I dont know one) application. As such a speed limit is quite common people either didn't care enough to tag it or maxspeed:wet was just a try. Also please don't forget that maxspeed:wet is up to this second completely undocumented. You (Pieren) are right if you say, that all things should be put on the table before voting. Put I also understand Ole, because if he would have written that maxspeed:wet should be deprecated I bet that a few people would have objected - people who have never used maxspeed:wet before or even heard about it ;-) As I already wrote: a significant number of maxspeed:wet are from me. So if this tag will be deprecated I have some additional work to do and retag them. But that's life: things change. Sometimes even facts change. regards, Martin 2012/12/4 Pieren pier...@gmail.com: On Tue, Dec 4, 2012 at 12:24 PM, Ronnie Soak chaoschaos0...@googlemail.com wrote: Are you against changing things in general ... ?

The intention of mentioning that a tag is not directly deprecated by a proposal is to avoid that people's votes will be used as the reason for deprecation. So we cannot say people have approved conditional restrictions, so it's already decided that maxspeed:wet is deprecated. But it is not a guarantee that the tag will never be deprecated. It just means that this is a _separate_ decision, i.e. we might decide to approve the proposal, but keep using the other tag nevertheless. However, in this case I think deprecation would be a sensible choice. Even as the author of Conditions for access tags, which iirc was the first proposal to document maxspeed:wet along with other such tags in 2009, deprecation would be fine with me.

Re: [Tagging] Status of maxspeed:wet
Quiet often if such a change is made (does not deprecate - recommend to stop using) it is by someone other than the original proposal author. Irrespective of this the proposal procedure is a RFC - Request For Change - process. What it does is to say hey guys, I think we should change this, if you agree vote for it and update any systems you have that may be effected.

[Tagging] Status of maxspeed:wet
Hi all, What is the status of maxpeed:wet? Is it now deprecated in favour of maxspeed:conditional or is it a valid shortcut? Any opinions? Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] Status of maxspeed:wet
The conditional access restrictions proposal did not specify that this :wet tag suffix would be deprecated (in fact it stated quite the opposite). From a developers point of view however, it is beneficial if we use a consistent tagging scheme, which is what the conditional tag was designed to introduce. I would therefore suggest switching to the new tagging scheme, however I'll leave you to decide for yourself. As always the anything is better than nothing rule applies in this situation.
