Announce: New and revised free tools for generating XSD schemas for UBL

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

Fellow UBL-Dev'ers,

I'm pleased to announce the availability of two packages (one new, 
one revised) that you may find useful in creating XSD schemas from 
CCTS models following the UBL NDR.

The two packages are:

  http://www.CraneSoftwrights.com/resources/ubl/index.htm#ods2ublgc  (new)
  http://www.CraneSoftwrights.com/resources/ubl/index.htm#gc2ublndr  (revised)

If you use as input the ODS expressions of the CCTS models for UBL 
2.1 found in these directories:

  http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/maindoc/
  (all 65 .ods files)

  http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/common/
  (UBL-CommonLibrary-2.1.ods only)

... then Crane-ods2ublgc.xsl will create the equivalent to:

  http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/UBL-Entities-2.1.gc

If you use as input the ODS expression of the CCTS model for the 
signature extension found in this directory:

  http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/common/
  (UBL-CommonSignatureComponents-2.1.ods only)

... then Crane-ods2ublgc.xsl will create the equivalent to:

  http://docs.oasis-open.org/ubl/os-UBL-2.1/mod/UBL-Signature-Entities-2.1.gc

Next, if you use the created two genericode files above, then the 
Crane-gc2ublndr package will create the XML-equivalent XSD 
expressions to those found in these directories:

  http://docs.oasis-open.org/ubl/os-UBL-2.1/xsd
  http://docs.oasis-open.org/ubl/os-UBL-2.1/xsdrt

As a local test you can perform the above transformations and compare 
the results to find them XML-equivalent to the UBL committee 
distribution files in UBL 2.1.

With these tools in hand, you can now create your own extension 
schemas and additional document schemas for UBL.  First you model the 
information in CCTS and then create the schemas using these free tools.

Remember that you do not need to use spreadsheets to create the CCTS 
model expression in genericode.  You can use any tool you wish to do 
the modeling, provided that the CCTS information is exported in the 
neutral genericode.

Note that the NDR checking that is currently implemented in the 
gc2ublndr package conforms to the old NDR 2.0 and not (yet!) to the 
new NDR 3.0:

  https://issues.oasis-open.org/browse/UBL-6

The new NDR 3.0 summarizes the approach of using the neutral 
intermediate format, including which columns are mandatory (there are 
many columns of documentary information in the UBL spreadsheets).

Please let me know (off list) if you have any problems recreating the 
outputs from the inputs, but from my regression on both BSD and DOS I 
am getting the equivalent results.

I hope this is considered helpful.

. . . . . . . . . Ken
