No, this puts the cart before the horse.
It worries about interoperability that doesn't exist and may not even need to,
instead of worrying about having a way of managing the data schemas that are
_actually in the system_.
A usual data dictionary is all about having a database somewhere around that
manages what tables (and contents) are used in the system.
There _will_ be data on the system that under NO circumstances should be
released externally, such as security configuration and personal information
(as is found in payroll). That should NOT get attached to any "ebXML" system,
lest mistakes lead to confidential information getting released, which could
lead to all sorts of horrid effects including companies getting sued.
And again, worrying about that is vastly premature. The point _isn't_ about
abstract XML schema; it's about the concrete question of what DBMS tables are
on THIS system, and how do they link to the INTERNAL functionality of GnuE, to
forms, business rules, and such. Forms are certainly not something that is
any business of outsiders.
