Artifact artf5307 : (1262) Should set resource property be included in BPv1?
Tracker: WSRF Basic Profile
Title: (1262) Should set resource property be included in BPv1?
Description:
[From Jan. 26 minutes]

There is an issue with whether a generic "set propery"
      should be in the basic profile. Many 'stakeholders' have no
      requirement to change properties, or think that if such
      functionality is needed then specific operations for each item
      should be defined. (Also there is an argument that such an
      operation is not in line with SOA, and so on.)

[Fred followed up on whether it is required or not be WSDM.]

I raised the issue at the WSDM teleconference earlier today.

First of all, from the MUWS part 2 spec:

"Specifically, the interface MUST include the GetResourceProperty
operation defined by [WS-RP] and MAY include the GetMultipleProperties,
SetResourceProperties and QueryResourceProperties operations."

So, SetResourceProperties is not mandatory in WSDM. In the configuration
capability, it says that:

"WS- ResourceProperties SetResourceProperty operation MAY be used to change
a configuration value."

Again, not mandatory.

So, whether SetResourceProperties is a MUST or not will depend on the
specific mapping from MUWS to a given domain. And in the teleconference I
was given a very good example, which is CIM. It is quite natural to do setup
on resources (configure, control, etc.) using SetResourceProperties (that
would be functionality similar to SetProperty, ModifyInstance, etc. in
WBEM). This single operaton should be enough. Conversely, if we don't use
it, we will need a *zillion* different operations (one for each and every
property in every class of the model?), which will be a pain.

So, no problems for now, but we (OGSA and WSDM) will definitely need to keep
in sync. And I'd say that their input above is valuable.

Regards,

Fred Maciel.

P.S. - For the WBEM operations, see:
