the pywiki (see
http://article.gmane.org/gmane.org.wikimedia.wikidata/910)
looks interesting. It seems Joan Creus is a very fast and active programmer:

so i dare to say that it would be great to have python scripts with which one could set
custom properties in Blender with
data from wikidata.
(
http://wiki.blender.org/index.php/Doc:2.6/Manual/Extensions/Python/Properti… )
so for example if one could read in the chembox item "density" (when this is
realized in wikidata)
from lets say iron via pykwiki then one could use this information for
a custom property for computing the mass of a volume (as modelled
in Blender). This could then be read in e.g. as the mass of a 3D model into Blenders
