[Announce] Commercial schema subset preparation service

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

Fellow UBL Dev List members,

As you know from previous posts of mine, the tools used by the UBL 
committee to create the XSD schemas from the CCTS expressions of 
business information entities are free to download and use from my 
web site.  These tools are used to create schemas for the UBL project 
and the BDE (Business Document Envelope) project, both of which have 
information models expressed using CCTS.

These tools have features supporting creating subset schemas.  Subset 
schemas work well in conjunction with the complete schemas in a UBL data flow.

Typically, one would use the complete schemas to validate incoming 
UBL instances to ensure that the received document conforms to the 
syntactic constraints of the standard.

Because of the (necessary!) magnitude of the formal specification, 
some document creation tools are overwhelmed by the complete 
schemas.  Here, the internal use of a smaller subset schema can drive 
software to generate the required documents more manageably.  One 
would still use the complete schemas after creation and before 
sending the document to confirm that the generation software did not 
violate any of UBL's constraints.  But because the focus of creating 
content is on only select parts of UBL, the creation tool works only 
with the corresponding subset schema and doesn't fall over dead from 
weight or exhaustion.

Having the free tools available is one thing ... making the time to 
install and configure the tools is another.

To meet this need, I am experimenting with offering, for a set fee of 
a fixed number of consulting hours, a schema subset preparation 
service.  In short, the client populates an online Google spreadsheet 
with their specification of the subset of UBL they need, they ask me 
for validation artefacts, and I return a ZIP of XSD files they can 
use with their software.  I will also accommodate code lists through 
genericode and CVA if desired.

I've outlined the process here:

I'm still working out the nitty-gritty details, but I hope this is of 
interest to some.
