First draft UBL 2.0 SBS 2.0 document models and schemas

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

Fellow UBL SBSC members,

Please find at the following address a ZIP package with the 
documentation and schemas for a draft SBS 2.0 for UBL 2.0:

   http://www.oasis-open.org/committees/document.php?document_id=23873

With many thanks to co-chair Gruffudd Williams for proposing this 
initial content, this is now a straw-man draft to convey the concepts 
of what we might put into a deliverable for a schema package for a 
small business subset of UBL 2.0.  This initial package customizes 20 
of the 31 UBL 2.0 document types.  Gruffudd based his work on 
real-world requirements from his experiences and he started with a 
clean slate rather than trying to build up on earlier SBSC efforts.

In UBL 1.0 the SBS 1.0 was described by XPath files.  In this 
proposal the UBL 2.0 SBS 2.0 is described by XSD schemas.

At this early stage we are only looking at document definition as a 
subset of UBL 2.0 and not any adjunct files (though this does not 
preclude examining adjunct files in the future such as the business 
process files).

The schemas were created by pruning the original UBL 2.0 schema 
expressions through the use of XML comments wrapping the constructs 
of UBL 2.0 that are not used in the subset.  There is a run-time 
version of the schemas supplied without the comments of the pruned content.

Please examine the HTML document reports for the aggregate and for 
each document type.  Each HTML document lists the model rows of the 
subset, hyperlinked to the model rows of UBL 2.0.  This combination 
allows committee members and others to examine what is in the small 
business subset and what of UBL 2.0 is not in the subset.  This 
allows members to propose changes by linking back and forth between 
the two tables and seeing what is missing.

At this time the division of labour is that Gruffudd is proposing 
what is in and what is out of the small business subset, and I am 
taking his work and creating the committee artefacts.  You are tasked 
with giving us feedback both on the SBS 2 contents and the SBS 2 artefacts.

Gruffudd is transcribing his work into copies of the spreadsheets 
found in the UBL repository at:

   http://www.oasis-open.org/committees/document.php?document_id=21034

I'm using some internal Crane tools to synthesize the schema expressions.

Gruffudd and I are now inviting comment from committee members and 
others regarding the choices made in the draft work.  If you are 
interested in participating in the work of SBSC, send us your 
comments and join our subcommittee.  We don't yet have any 
teleconferences scheduled and plan for the time being to work by way 
of the committee mail list.

BTW, Gruffudd will soon be creating some sample instances that 
validate against the UBL 2.0 SBS 2.0 draft schemas.  At some point we 
should also look at code lists.  I'll prepare some XPath files from 
the schemas.

We look forward to your feedback!
