RDF defines the more > flexible data structure of graphs It probably doesn't matter for this discussion, but I've seen statements like this too often. XML actually can represent graphs perfectly well. One way is by using ID/IDREFs, and there are many other ways. Just because an XML document reads serially from start to finish doesn't mean it has to represent a tree instead of a graph (leaving aside the matter that a a tree is a particular kind of graph structure!). In fact, that's obvious because the XML syntax for RDF interchange describes RDF graphs. XML elements (the ones without ID values, anyway) can be considered to be typed anonymous nodes. You could regard them as bnodes that have a type relation but not an ID. TomP
