In order not to loose the Dim-data that is already available from the
Wikipedias, and to use this for scaling. It should really only describe the
rough dimension. I would expect that a building would still have something
like "area" or similar in its own property. Dimension is used for scaling
and uncertainty.

Yes, maybe "dimension" is not a good term. "scale" could be better, but I
can see in the GeoData extension that there was a shift from scale to dim,
so I assume they might have reasons for that. I put Max Semenik into the
discussion, and hope he can enlighten us a bit on it, since he was working
on this for far longer than me.
