Sorry, not convincing. Why is that tree model fits "naturally" into XML, but graph model doesn't? Or XMP propellerheads do think that they can handle graphs too? Could you easily solve graph problems in XML? Find the shortest path in a graph, for example?

If I want to learn about graphs, I'll grab a Graph Theory book. It described Matrices, Cuts, Flows, Graph Spectra etc. First Order Logic has little to do with this area. Neither XML. A suggestion that some sloppy tag manipulation is a superior technique that naturally embrace hierarchical structures is just hillarious. Received on Thu May 15 2003 - 18:30:09 CEST
