As I recall it from , this was proposed as a way to describe a _single_ source of an object while still maintaining a One-To-One position. No further recursion should be permitted (those complicated relations should be handled by DC.Relations. This implies that DC.Source.X should be acceptable for any element X belonging to the DC element set, if and only if X is not equal to source, and I would suggest relation. > > --Erik > > Erik Jul > [log in to unmask] Sigi
