RE: [wsdm] Terminology in the requirements

["Andrea Westerinen" <andreaw@cisco.com>]

John, Thanks for the ideas. I was worrying that various interfaces may
not support the same "capabilities" (which the resource has from
design/implementation time onwards). As we discuss this, I am warming up
to the idea that capabilities is everything that the resource can
supply/do wrt data + events + operations.  I agree that my word of
"information" is probably more confusing than "capabilities" :-).  I
withdraw this.

I like your new definitions of Manageability Configurability and
Configuration.  However, this still does not distinguish that different
interfaces may not be able to support/provide all the data + events +
operations. What worries me was that the resource has "capabilities",
but that the interfaces may limit what can be expressed/exposed.  This
was not clear to me.

Andrea

Andrea,

I agree more with Mark on this issue.  After all, there are capabilities

in general and capabilities of a resource - those are two distinct types

of things.

A manageable resource has a set of manageability capabilities that are 
set at design/implementation time.  And it can be configured during its 
lifetime.  We actually have requirements to be able to turn on or off 
certain manageability capabilities.  In fact, a managed resource may be 
configured to turn off all of its manageability capabilities (depending 
on interpretation of the requirements).

Also, we highlight in the requirements that things can change during the

runtime/lifecycle of a manageable resource.

However, I like the idea of defining MANAGEABILITY CONFIGURATION.  While

I agree with Mark that it is meta data, it could make it clearer to 
people that runtime changes need to be reflected somehow.

Properties, operations, and events all can be configured by management 
(including self management).  It would be nice to make it clear how to 
access the current configuration.

MANAGEABILITY CONFIGURATION is the set of meta data about a managed 
resource's current state of its manageability capabilities, that is 
needed for a manager.

MANAGEABILITY CONFIGURABILITY is the possible range of states each 
manageability capability can be in for a given manageable resource.

What do you think?
