Dear, Does anyone know how to implement the type of structure described here http://xanadu.com/zigzag/ ? The structure can be seen as a group of oriented graphs, for example: 1->2->3->4 5->2->3 6->3->7 where each subgraph has respectively name: d1, d2, d3 I'd like to manage such structure, so: - select node with subgraph in common. for the example above the intersection of d1 and d2 is node 2 and 3 - append and remove node to a subgraph - append label to node and so on. Which programming pattern should I follow? Is it better to develop this structure in .Net and then use the .NET/Link ? Could anyone give me an hint ? Gabriele
