Ontology for geometric data?

Hello,

I have recently finished a small research project in which BIM data from an
IFC file were to be combined with geographical (GIS) data. A Linked Data
based approach was also investigated, So it was an example of something
that should be made possible by Linked Data: combining data from different
domains. A known but difficult problem arises when this is tried: the
information models and data formats for geometry in BIM and GIS are
fundamentally different. Even when GIS and BIM data are made available as
Linked Data, their geometric data are not interoperable.

So my question is: Is anyone aware of an attempt to have more general
(domain independent) specifications of spatial data on the semantic web? Or
is this perhaps something that this group has already set out to do?

Regards,
Frans
