Hi,<br>
<br>
Some data of the map changes often, in particular what's on the
road: traffic signs, bus lines etc.<br>
It would be interesting if someone tackling a region could determine
what in his interests was checked the longest ago. Hence the need
for a date at the beginning of the data that is not of the source of
information if any but that indicates when that source, visual
observation or other was still current last. The someone would deal
with the oldest in priority and update that date if that can be
said. The data field of the query result would be sorted to
determine the oldest ones.<br>
Is the source:survey date appropriate for that, pardon my limited
English ...<br>

Not the seemingly appropriate #4, but #7 looks like the right word,
isn't it.<br>
Anyway, I let you natives decide.<br>
Or we just use no word and just put the date first on the
source:data line.<br>
<br>
But now comes my computer science remark that <tt
style="background-color:#dde; white-space:pre;" dir="ltr">"10
November 2012"</tt> is not appropriate because it does nor easily
sort chronologically. And hence I suggest to update the wiki to use
the ISO format 2012-11-10 instead.<br>
<br>
Would someone versed in overpass queries confirm that such a query
can be done sorted, or with a possible use of a post-processing
script to format and sort the output?<br>
<br>
But now comes that clash again. This generalized good practice is
difficultly applicable to maxspeed.<br>
<br>
And that maxspeed thing is the strangest one ever.<br>
source=* almost says that <tt style="background-color:#dde;
white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt> is an
admitted mistake but that you are not compelled to make the mistake
and that you are allowed to correctly use <tt
style="background-color:#dde; white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:maxspeed:type"
title="Key:maxspeed:type">maxspeed:type</a>=*</tt>.
Furthermore, if #1 uses a wrong <tt style="background-color:#dde;
white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt> and then
#2 comes to add a correct <tt style="background-color:#dde;
white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt>, then #2
has to change #1's <tt style="background-color:#dde;
white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt> to <tt
style="background-color:#dde; white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:maxspeed:type"
title="Key:maxspeed:type">maxspeed:type</a>=*</tt>. before he
add his correct <tt style="background-color:#dde; white-space:pre;"
dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt>.<br>
And as we are #2 when generalizing <span
style="background-color:#dde; white-space:pre;"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=survey</span> we
are making using <span style="background-color:#dde;
white-space:pre;"><a
href="http://wiki.openstreetmap.org/wiki/Key:maxspeed:type"
title="Key:maxspeed:type">maxspeed:type</a>=*</span> mandatory.<br>
Furthermore the correct <tt style="background-color:#dde;
white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:maxspeed:type"
title="Key:maxspeed:type">key:maxspeed:type</a></tt> article
almost deters from using it and key:maxspeed shows a sole <tt
style="background-color:#dde; white-space:pre;" dir="ltr"><a
href="http://wiki.openstreetmap.org/wiki/Key:source:maxspeed"
title="Key:source:maxspeed">source:maxspeed</a>=*</tt> as useful
combination.<br>
And, of course, national wikis will overlook maxspeed:type entirely.<br>
<br>
Couldn't that maxspeed problem be fixed logically?<br>
<br>
Cheers,<br>
