WS-RF Resources vs. WSDM Resources

One of the things we would like to do in WSDM 1.1 is to make
sure that when the text refers to a resource, it is clear whether the reference
is to a WS-RF Resource or a WSDM Resource.  The fundamental difference
between the two, as I believe has been discussed, is that a WS-RF Resource is a
“logical entity”, well, something abstract, whereas a WSDM is
anything that is of interest to manage.  As editor of the MOWS spec, I
started this AI to make sure the text was correct and consistent by looking at
the so-called “mind-map” in section 2.4 of the MOWS spec.  The
most significant thing that the diagram does over the corresponding (but
slightly different diagram in section 2.3 of MUWS Part 1) is to make a Web
service endpoint a “resource”.  Is that really what we want it
to say—isn’t the “resource” under MOWS the Web service
that is being managed, not its endpoint.  At any rate, the use of the “resource”
still left open the whole question of what is the relationship between a WS-RF
Resource or a WSDM Resource—which is it?

 

Also, I believe we have eliminated the notion of the “manageability
capability interface” as a specifically specified “thing” that
represents 1 manageability capability in recent decisions about what a
Manageability Capability is. Is that correct, Bryan?  At
least, it seems to be a subtlety that could be eliminated.

 

So, I have attached another mind-map, which, IMHO, better expresses
the relationship of Resource, WSDM Resource and WS-RF Resource.  By just “Resource”,
I refer to one of the general definitions of “resource”, e.g.,  IETF,
W3C, or an RDF-definition. Comments would be appreciated—if only to make
sure I’m on the right track.

 

This is also a “straw” poll for what to do about
section 2.4 of MOWS?

 

 
Keep the section and diagram as it current is?

 
Replace with it with the attached (perhaps with minor
     tweaks)

 
Whack the section and forget about having a “mind-map”.
