I'd only like to add, I hope clarifyingly, that the grove-ified properties of an information object need not resemble the original representation. For example, groves built according to the HyTime property set do not resemble the syntax of HyTime documents. HyTime hyperdocument groves are the result of a HyTime engine's processing of the set of objects comprising the hyperdocument. Let me invent a sillier example, to dramatize my point. If, for example, I have a sufficiently pathological fetish for human noses, it may be that the only thing that interests me about movies is the noses that are depicted in them. I may wish to address the movies entirely in terms of the noses that appear in them, and so I may represent movies as groves based on a property set that consists entirely of a catalog of noses, or noses in various states, and/or camera angles in which noses are captured, etc. etc. The grove won't look much like a movie at all, but it will serve my pathological purposes quite admirably and efficiently. In the grove paradigm, *you* get to decide what's important when you create the property set. -Steve -- Steven R.
