RE: workable IFC-RDF conversion?

Hi, We use custom SPIN-rules that apply a general (custom) mapping from IfcOwl to the proprietary ontology.
This does not include geometries. I think I would just use the EXPRESS file as a property value (if feasible). -Jan

Hi everyone!
What do you use to convert IFC to RDF with workable geometries?
Representing geometries with individual triples (eg EXPRESS lists, as IfcOwl does) is imho not workable.

We've tried IFCtoLBD but there are various issues
- see for a diagram
- see for a list

Thanks in advance!
