converting an IFC file to an xmi file conform to

[amine-ben]

Dear contributors, I might be in the wrong place to ask this question my deep apologies. I want to convert an ifc file to an xmi file conform to ifc.ecore using java code. Is OpenBIM providing a library to do so ?

Any pointer hint is very welcome

Thank you a lot in advance Kind regards

This code will do that, it requires the latest BIMserver codebase (GIT HEAD).

Make sure you run it with the proper "-plugins" program arguments (https://github.com/opensourceBIM/BIMserver/wiki/Eclipse#adding-the-plugins-property).
