Dave-

To clarify what I think you're talking about:

1) Functional differences between CMOT and CMIP - in comparing the two
documents, the only functional differences I can find are that CMOT does
not include the current CMIP addenda, namely CancelGet and Add/Remove.

2) ASN.1 data type differences - I think what you are refering to is what
falls under Structure of Management Information (SMI) in ISO.  The ISO SMI
includes some data types that weren't used in the Internet's equivalent
document (rfc1065 - Internet Structure and Identification of Managenet
Information for TCP/IP-based internets).  However, the Internet document
also defines some types that aren't in the ISO documents.

The ISO work in this area is far from being turned into final standards,
although their basic data type definitions have been fairly stable over the
past year or so.  The intent in ISO is to give a basic set of data types
that appear to be generally useful -- not to define a cast-in-stone set
of definitions that have to be used.  

Furthermore, the data type definitions are a separate issue from CMIP.  CMIP
merely provides the means to carry the information.  It doesn't care what the
contents of the data are.  Thus, a vendor could implement CMIP with the
current Internet data type definitions and change these definitions at a
latter date without having to change their CMIP implementation.

On the subject of GOSIP - GOSIP version 1 and the draft GOSIP version 2 do
not specify network management yet.  GOSIP's stated intention is to follow
the work being done in the NIST workshops.  Since the NIST NM SIG has not
yet finalized its work, it is not yet included in GOSIP.  NIST, however,
is closely tracking the ISO standards.

Hope this clarifies things somewhat,
