That's right, DAM would need to be changed in order to work with our
implementation.

However, it would be possibly to adopt the DAM without dropping any
features, right?

I know that with your implementation you could for example store the
"customership" relation in the same table as the "employment" relation
(both are persons <=> companies relations).

My question was if you could make an example of relations that are not
possible to store the way we implemented it.

My clear answer is: No, everything that can be done with matchfields can
as well be done with multiple mm-tables. Do you agree?

What do you mean with "for the DAM this is not working"?

Of course it doesn't work out of the box but would need to be adopted.

Couldn't that as well be done with the field type "user"?
