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 _(object)s, 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| http://www.xanadu.net/zigzag/) for a fuller explanation and look into the _(Perl package| http://freshmeat.net/projects/zigzag/) presented on _(Freshmeat) to demonstrate the idea. Actually, there seem to be at least two other implementations.
