RE: Closing on NIM requirements

["Durham, David" <david.durham@intel.com>]

I am still trying to grapple with the idea of methods within an information
model. What does it mean to model methods in a declarative model which I
generally view as classes, attributes, and associations? Methods seem to
break repository models (which do not support them directly) as well as
protocol models that strictly set/get or add/remove named data (eg. SNMP). 

I view methods as being useful as mechanism for grouping attributes and
expressing the transactional semantics of attributes. Other than that, if
they are meant to imply CORBA/DCOM IDL-like notions, then I don't think they
belong in an "information model" because they are forcing it to become
implementation dependent.
