RE: [xml-dev] CCTS NDR tools for generation of schemas

["Webb, Sylvia" <SWebb@gefeg.com>]

Brian,

There are no NDR for CCTS.  CCTS is payload neutral. With properly
defined NDR you can create XML, EDIFACT, or other formatted payloads.
UN/CEFACT has defined a set of NDR to create profile XML based on CCTS.
This is completely different from CCTS as a standard.

Please contact me off-line for the name of your colleague that purchased
the GEFEG.FX software. It will assist you in the creation of CCTS data
models and UN/CEFACT schema. It is the same software used by the
Northern European Subset (NES) user group.

For most business people it is easier to understand non-technical
graphical representations of data than to understand how to read schema.
This may be one of the reasons for the request that you have received.

Subject: [xml-dev] CCTS NDR tools for generation of schemas

hi,
someone I'm working with will soon be arguing for wholesale adoption of
the CCTS NDR and using as their argument that users will be able to
generate schemas just by writing models as opposed to having to deal
with the complexity of schemas.

This seems pretty wrong headed to me, but I must admit I am not
knowledgeable enough about CCTS NDR and the modelling thereof to know
how advanced any applications for doing this modelling are. I am going
to assume not really too advanced.

An especial quibble I have is, yes it may generate schemas from models
but will schemas generated from models be able to work in a broad cross
section of processors. It seems somewhat wrong headed to expect
automatic execution of schemas from models when processors for schemas
often have a lot of incompatibilities.

I am also more apt to think that writing code is preferable to
generating code, partially caused by the experience I have that making
the models is as complicated as writing the code in a lot of instances.

Cheers,
Bryan Rasmussen
