Re: [ubl] about the relation with CCTS

[Tim McGrath <tmcgrath@portcomm.com.au>]

I am not sure we would call it a simplification, but you are correct UBL 
only defines BIEs not CCs.

Core Components are abstract (syntax-independent) definitions that take 
physical form as BIEs.  So we can have a CC for Address that is 
expressed as a BIE called Address in UBL and a BIE called Location in 
another syntax or another vocabulary.  BIEs share the same basic meaning 
as their orginal Core Component but have been contextualized to be used 
in specific circumstances.

The problem with this approach is that UBL started before any Core 
Components had been defined by the ebXML Core Components group.  UBL 
assumed that behind each of our BIEs would be a CC of some kind.  But it 
was not our role to define these.

Unfortunately it has taken UN/CEFACT some time to re-organize its 
activities and only recently did the UN/CEFACT's TBG17 (the inheritors 
of the ebXML CC task) announce their first 21 draft CCs. We submitted 
our BIEs to TBG17 as "candidate core components" and are now working 
through the process of how we align our submission to be more TBG17 
friendly.

So the short answer is, UBL does not (and should not) define CCs - the 
world only needs one of these and the UN seems the best place to do this.
