[regrep] Implementing CCTS in Registry - further thoughts

[David RR Webber - XML ebusiness <Gnosis_@compuserve.com>]

I just reviewed the Section 7 of the CCTS spec' again,
and the UML models.

This is actually significantly simpler from the earlier
UML models that the first CRI work had to tackle.

I believe the behaviours that are described in Section 7
can be implemented by a combination of:

1) A new CRI structure to capture the semantic nodes
     that are specifically identified in Section 7

2) The CAM mechanism to implement the BIE
     mechanisms, cardinality and context mechanisms.

3) Normal Registry RIM behaviours around 
    associations, versioning, unique IDs, classifications
    and so forth.

4) Datatyping and other physical layer information 
    that comes across from the industry dictionaries
    which is of course missing from the CCTS logical 
    layer - but is vital for actual payload manipulation.
    This manifests itself as an extension to the CRI to
     provide physical layer details.

Having said this - its definately not just a "weekend hack".

I'd say we're lookinig at three to four months of effort to
get this spec'd and agreed to.

The good news is that I do not at this point see any
need to extend the RIM itself - just show how to
utilize it + excellent XML structures - to deliver the
required behaviours.
