Yes, I think it should be taken from the metadata set definition.

What about just not exporting the metadata if the metadata is not filled
in locally but is acquired instead. After all, the object doesn't have
any metadata directly associated with it, so why export that? 
I, um, had hoped that this was already the case in the implementation
as I recall discussing this in the past as the right solution...

This way an object will gain the metadata of whatever context it finds
itself in upon import. I think this is usually the intended behavior,
but perhaps people disagree.

Unless people suggest that this is frequently not the intended behavior I'll try
to move the metadata system into that direction.
