That should be no problem.

This is the responsible of the destination application - this is exactly
as it is implemented in the app property. One can link items from
different sublocation within property - each holding their own
customizable fields.

I think of the link only as a many-to-many relation between items - but
of course - in addition to the relation information itself - it can hold
information of validity, user who made it and so on...

Well - I think this can be modeled as a static set of rules and methods
or triggers to be performed to a item at a specific location when an
item is linked.
Example: a linked document could be displayed in the link with name and
status - and possible a tooltip reporting stuff like name of responsible.
Of course - the rules could change depending of the role of the item
(origin or destination)

This should be no problem - and is what we are aiming for.
