A component of the Xanadu hypermedia system which consists of a multi-dimensional relation structure. That is, the user sets up chains of arrangement of objects, and each object can be within multiple dimensions.

The dimension term is a bit inappropriate, since it is not like a physical dimension: they are not necessarily dependent or independent of each other. Really, the dimension is just a way of grouping chains together.

While the concepts are rather expressive, perhaps they are too simple, and certainly it's not implemented in some immediately accessible way for the average user.

See the Xanadu.net site for a fuller explanation and look into the Perl package presented on Freshmeat to demonstrate the idea. Actually, there seem to be at least two other implementations.

This just just a token review. Please try it out and attempt a better explanation and critique here.
