Re: [regrep] [TN Proposal] Mapping Business Information Models toebXML RegistryInformation Model (Was: [regrep] UN/CEFACT-ICG adopts freebXMLRegistry)

Duane,

I do not buy your model here.

When you use jCAM and the noun definitions we are developing for SCM - 
you head all these problems off at the pass.

This was the lesson we learned from the CEFACT work - that you need to 
separate the assembly mechanism from
the noun representations.  We did that and moved on.

The context is then managed and exposed by the CAM templates themselves 
- and since they are simply XML instances
you can query across them by UID ( *not* UUID) and garner the 
associations and usage easily.

And the noun definitions as defined are covering off the gaps that the 
RIM and UMM models of CC are not accounting
for.  Again - no giant surprise here - thats exactly what we deisnged 
them for an have foreseen - the difference between
the model layer and the implementation layer.

Next up we will be working with the CEFACT folks on implementing this in 
registry - so they should be able - as
noted in the CEFACT meeting - be able to take the existing ISO 
dictionary work - use the noun definition format - and
store those semantics into registry.

The jCAM engine can then read and apply those from the registry during 
either validation of assembly of content or both.

Thanks, DW
