MySketchUp should be able to open/edit/save and/or import/export COLLADA (dae) files

COLLADA is a real standard which have wide adoption in industry (see list of supported CAD applications). It always here that is why My.SketchUp MUST support it natively.

Supporting a Parasolid format is optional but may be worth well if My.SketchUp will pretend to stand like a professional CAD system because X_T is a real thing for the great projects developers.
