Hmm...

 

According to the diagram

 

One consumer interacts with many services. why can't many consumers interact with one service as well? There are a few similar problems with cardinality that I see on the diagram.

 

Using WSDL I can create a description of a service which endpoints belong to different providers (owners). How would that work with the expressed set of concepts?

 

As per our earlier definition manageability capabilities are merely a set of distinct semantics which could be expressed in a model. I can see how a capability could *represent* how to monitor/control along with other things, but I don't understand how it would actually do that. This is like saying that an interface monitors/controls something. That is never so, an implementation of an interface could do that. So, IMO, manageable resource is the one that offers monitoring/control of itself. Conceptually. Implementations may vary e.g. a manageability service/endpoint implementation may internally be able to control the *resource*. The resource + its controls (implementation) = manageable resource.

Appologies for  missing the last Uarch call. Attached is a proposal for the roles and relationships model (or logical concepts model) for the teams consideration. There are similarities to the diagram that Igor proposed, but they differ in some aspects:

 

* the manageability provider provides a manageability service, not the manageable resource

* a manageable resource has an associated manageability provider for it manageability service

* the diagram is service as opposed to endpoint centric

* the manageability consumer manages a manageable resource by montoring and controling using the manageability capabilities

On the last Uarch call I promised to send a logical model formalization in UML. The diagram is attached. The words to PRECEDE the diagram are as follows (assuming the roles of manageability provider and manageability consumer are roughly defined).

"
The manageability provider may provide many manageable resources, instances of which belong to one instance of the provider. To do this, manageability provider maintains manageability endpoints which provide access to manageable resources. Manageable resource is a resource with a number of manageability capabilities composed into it. Manageability capabilities are explicitly supported by the manageability provider and are offered via manageability endpoints.

The manageability consumers deal with manageable resources. To 'deal with' in this context means to exert control and to obtain and interpret the information. In order to deal with the manageable resource, consumers access manageability endpoints and exrecsise offered manageability capabilities. To 'exercise' in this context means to make use of the distinct semantics defined for a given manageability capability. Technically, it translates into being able to use a distinct group of properties, operations, events and metadata by exchanging messages with the manageability endpoint.
