Any suggestions or ideas about how to add metadata to a 3D model?

@nafergo The #COLLADA and also the #X3D file format allows to add custom structured metadata fields (XML) within the model file itself.
If you need (semantic) annotation of parts of the 3D model, then probably a "Repository Infrastructure" as proposed by the #3D-COFORM project would be the way to go (e.g. see http://dx.doi.org/10.2312/VAST/VAST12/041-048).
