<p class="MsoNormal">Hello,<o:p></o:p></p>

<p class="MsoNormal">Osmose is giving an error at many places
around the R50 trunk with reason "access=yes|permissive allow
all transport modes" and additional info "Including ski,
horse, moped, hazmat and so on, unless explicitly excluded".
For example, this way [1] has the error [2].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The road is clearly signed as forbidden to
pedestrians, bikes and moped. [3]<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm not sure how to improve the tagging to
resolve the error.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Should I remove the entire "access" tag ?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Or set it to something else, like
"access=designated" ? The road is not designated as for motor
vehicles only and hazmat is not forbidden, but if care enough
for you horse, you wouldn't let it go there :-) and nobody in
his right mind would try to go ski there even on snowy days…
:-)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What do you suggest ?</p>

Access tags are only needed when they contradict a wider scope
access tag or rule.<br>
access=yes is never necessary when there is nothing forbidding
general access (the highest scope).<br>
Just like bicycle=yes is not needed when no other tag or rule
forbids bicycles.<br>
But in access=no bicycle=yes, it is needed because allowing bicycles
contradicts forbidding all traffic.<br>
<br>
Although there is no nuisance allowing with *=yes what is already
allowed, I advise to remove them because many contributors do their
mapping by copying the tags of similar cases. And those too many
unnecessary *=yes are not exactly teaching them this fundamental,
very basic rule of the access tags: they are confusing.<br>
(it's a pity to find a whole list of bicycle=yes foot=yes horse=yes
etc. when nothing forbids them)<br>
<br>
But access=no motor_vehicle=yes make much sense if that's the
intention (horse=no too, not speaking of elephants).<br>
<br>
