Hi,
I wonder what is the best way to determine city boundaries based on the
OSM dataset. What I want to do is simply to have each city colored in

Hi!
I don't think we have something like that, as - see above - the big
question here remains: what is an urban area and what is a rural one?
I think there is no such thing in OSM yet (and I doubt there ever will be).
But to help think about it, here's a definition of the national Austrian

In Germany the speed limit is the case by default, but in the city there
may be different limit signs even increasing that.
One problem with this kind of boundary is, that it's only defined
along streets, not on every small way and not in between.
One proposal to tag this is [1],

It is not as easy as it sounds like. Actually we often do not have
this information (directly) in OSM. What you could do is:

One of the reasons is IMHO, that the main mapnik map uses external

Official city boundaries can be very different from the common-sense
boundaries; for example, only about half the population of the
built-up area of Limerick is within the official city boundary (most
