Gzz and Leszz both use variants of XML.

Gzz.xml consists of a cells list followed by lists of dimensions (and the 
connections in each one).
Leszz.xml consists of a list of cells where each cell contains a list of 
connections to each dimension.

Either format is easy to produce by a fully-zz-enabled application.
Outside that environment (e.g. using awk to process a slice in order to 
produce a data file to send to a graph drawing program) either one of these 
perspectives may be most useful, depending on the app. (Unsurprisingly, I 
have so far found the Leszz form to be most helpful.)
Perhaps an interchange form should redundantly contain BOTH perspectives.

Of course, in the future there will be NO applications which are 
zz-unaware, and the above is not a significant point :-)

Leszz also contains a lot of other stuff (tutorial defn's etc) which should 
soon be folded into the cell structure.
