You might have a different idea about it, but IMHO osm tags are describing objects and functions, they should not (and are generally not) metadata describing the data itself instead of the object. Yes, I could put a tag on every edit saying insertion_date=2014-03-21 or "last-time-modified=2014-03-21", but if I did people would object (I think). In which way is "source" different? And why would the key for the source of a maxspeed be "source:maxspeed" and not e.g. "maxspeed:source"? It is mostly arbitrary, so why bother to redefine a well introduced tag instead of making up a new one?<br>
<br></div><div class="gmail_extra">IMHO if you map something and you make up a new tag it should be really _new_ and not a tag that others use for a different purpose (or you will surely get problems sooner or later). When we started to use source:maxspeed in 2009 there were 0 occurences of this (there were also 0 occurences of maxspeed:source, which btw. I would have preferred personally, but some prolific local mapper preferred source:maxspeed by the time and I didn't mind as none of both was in use then).<br>
<br></div><div class="gmail_extra">Anyway, if you do normal mapping you can do whatever you like, but if you perform an import you should not distort the stats by using tags in an unconventional way. E.g. the values <span><span><a href="http://taginfo.openstreetmap.org/tags/source%3Amaxspeed=EMUiA%20UM%20Ostro%C5%82%C4%99ka" target="_blank">EMUiA␣UM␣Ostrołęka</a></span></span><span> and Stats19 seem to have been imported (or manually introduced by manual imports) in the past year.<br>
</span></div><div class="gmail_extra"><span>One example for the Stats19 is this here: <a href="http://www.openstreetmap.org/changeset/17880000">http://www.openstreetmap.org/changeset/17880000</a> (which doesn't look like an automatic import admittedly). <br>
