Re: [ubl-dev] UBL and CCTS: Improvement interoperability ?

Mark,

Concluding from your replies there are only two full implementations of the CCTS if one categorizes a full implementation as having to comply to:
1) the use of the base data types as specified by the UN/CEFACT in the data type catalogue
�
2) the conceptual and logical data model


I still have a few�questions: 
�
- In what perspective do the GDTs of SAP differ from UBL or UN/CEFACT ?
-�Does it�mean that CCTS standardized the logical data model ? Why can other standard organization not develop their own data models ? 
-�What is the role of�the CCL ? Can interoperability not be established if one ensures there is one common CCL ?� If every standards organization refers to the CCL and used for example the unique id in their definitions then it is just a matter of mapping values belonging to unique ids. Is that not what the UDEF is aiming at ?
kind regards,
Danny Gaethofs

Ken - this might come as quite a surprise to a number of standards
organizations, government organizations, private sector companies, and
service providors who have CCTS implementations completely independent
of UBL.

Ken - The DT interoperability is just one aspect of the interoperability
of CCTS.� Yes people are referring to the base data types from CEFACT,
but much more importantly, they are doing this in the development of
their syntax neutral data models.� The DTs are the basis for both the
conceptual and logical data models.� The conceptual data model and
semantic focus are the keys to interoperability as every logical data
model is derived from a single ubiquituous data model.� The XML is a
trivial piece in the importance of, and interoperability created by,
CCTS.
