David,

I think you grossly misinterpreted my posting below. The concepts in my
posting are actually completely in line with many of the presentations
you have given on this subject, including those very recently.

<Quote1>
standardized names does not increase interoperability
at all.
</Quote1>

That was not explicitly stated nor implicitly implied in my posting
below.

<Quote2>
Add to this the CAM ability to capture the business
semantics associated with the business process and
transaction interchanges - then you have the ability to
understand the information that you are receiving.
</Quote2>

Yes I know.

<Quote3>
Just knowing what the name of a field is does not cut it,
nor does just assuming because its the same name,
that the information is the same.  The means behind
how the data got into that field is critical information.
</Quote3>

I think you're preaching to the choir here. ;)
