RE: [ubl-dev] XML NDRs: UBL 2.0, 2.1, CEFACT 2.1, 3.0

Roberto,

Not sure why you went into code lists as I didn't address it in my reply at all.  Rather I just focused on the difference between CCTS and NDR and did not address any differences between UBL and UN/CEFACT.  You may want to do that analysis yourself, especially for v3 which creates specific packages for specific deliverables which is a paradigm shift in how standards are developed and delivered in that it breaks the monolithic approach.

Kind Regards,
Mark

Hello Mark,

I am not an expert of CCTS 3 but I noted CEFACT schemas are too much
binded with enumerations for code lists.

Code lists are required to be updated separately from the business
document.   Real business needs cannot wait UN/ECE or CEFACT deliverables,
so for instance using UN/Locode most companies are required to add
additional codes for new Port entries that are not available in the
official code list.

We have already seen similar issues with currencies the past year (see
Turkey) and I am happy that UBL TC has choosen to decouple code lists from
business documents.

Anyway I am not surprised at all as UBL has provided always good examples
for ensuring interoperability.

UBL is standardized within an open process under OASIS OPEN, and this
reason UBL collects requirements from a wide community and committed
people for doing business not only standards.

It is a fortune that UBL is working together CEFACT.

Take care

Roberto
