Hi, oh yes Ted Neslson's Xanadu stuff. Quite old but gives a good new POV if you find a way through the web-site and document mess that won't confuse you to much ;-). I'm thinking about this stuff and merging it into my rebol-framework approach. It's not that hard as the idea is quite simple (at least what I did understood so far): 1. You have a set of nodes (or cells) 2. You have some qualified connections between nodes (all nodes that are surnames are connected) Now you can view at your data a long a qualified connection line (dimension): All surnames AS vertical ordered list. Walking through dimensions is most like traversing a graph only build from a specific node type (all surname nodes). The idea is now not to store the type of a node with the node-object (as I do it at the moment too) but instead to specify the type of a node by including it into the surname dimension. I like the idea because now a node can be part of several dimensions. What's important is that we are talking about navigation nodes (not mandatory data nodes). Why would you need this? You now could have the same node that is part of a project dimension, a person dimension a rate dimension and a date dimension. The node would have associated data-nodes for the different dimensions representing the Bos. With the use of a navigation-node you now can create quite complex queries like: give me all nodes that are part of the project, person, rate and date dimension. If you have these nodes, you could create an invoice from the data-nodes ;-). I hope you understand what I mean and I'm mostly sure it's not exactly what zigzag offers but hey it's a first step.
