This is BTW a quite critical/interesting issue: Since values can  
contain proxies[1], proxies that contain such values are tied to the  
runtime environment that manages the proxies; they cannot have  
standalone significance (as opposed to relational results (...or RDF  
triples)). Will the proxies-in-values be object references? IDs? Will  
such IDs be meaningful accross restarts of the system where they have  
been obtained from? Are those IDs subject indicating properties then....

I once read that part of the success of the relational model is that  
it did away with system dependent references...but that is surely  
another story.

Lars - good that you ask these questions!


[1] These values form the edges of the graph, BTW. Since a value can  
contain more than one proxy, a TMRM topic map is a directed  
hypergraph. (In case anyone cares :o)
