STL (and .OBJ) are common exchange formats for mesh output. For solids, which FreeCAD and OpenCASCADE mostly deals in, the typical exchange formats would be STEP (and IGES). Solids can have perfect circles, surfaces etc - where as meshes are just a bunch of 3d vertices with straight line between them. But still there is much information not present in a solid exchange format, like how the model was made: Constraints, feature operations, constraints, undo stack etc.

Ah yes I meant STEP instead of STL of course, always mix those up. OCCT does not even have support for STL or OBJ import/export.
