Actually, we need an engine for this purpose, and, even more important, * the ability to plug that engine into our doc processing applications, and * the ability to inherit the information architecture that that engine understands into any other information architecture. Sounds like the proper role of the grove paradigm, with property sets for inherited architectures. XML Schema is getting there, but it's not quite there yet. > c) We won't have a simple universe, so there will be more than one > document specification for the same kind of transaction.

What's really needed is a formalized property set for each information set that is conveyable by each information architecture. With such property sets, arbitrary conversions become possible, and hooking each architecture's engine to each other architecture's engine becomes a piece of cake. Yes, we certainly need a repository for such property sets. Sounds like the role of xml.org to me. > d) And finally interpreters or parsers+interpreters that can > validate a document and interface with back ends ERP. You're describing architecture-specific engines for creating property-set conforming groves from interchangable resources. Groves are, by definition, ready to connect to ERP or any other kind of application. > Actually DTD is insufficient to provide all necessary information, Right. You need not only an interchange specification, but also the abstract information set. That's what a property set is supposed to be. There is a lot of confusion out there. The simple fact is that we need BOTH an interchange spec AND an abstract information spec in order to efficiently interchange any particular kind of information in an application-neutral and vendor-neutral fashion. > Schema is not yet a recommendation.

And that's a completely and easily supported scenario, given inheritable architectures, property sets, and groves. -Steve -- Steven R.
