Hi Jan,

This is an issue that we have bumped into as well.

However - I would like to characterise the problem slightly differently. For me it is not so much that you "lose the typing information" - I think the types are still there (either explicitly or implicitly) - the problem seems to be how do we characterise what is the intended "major" node within the graph.

As you say with XML it's easy because it is ordered - the root node is presumed to represent the major node. But with RDF it's tricky.

The best we can come up with at the moment is to attach a property that is unique within the graph being posted that allows us to say "this is the major node". It's not a very generalised solution though.

Cheers,

Murray
