Project: Open Grid Services Architecture Tracker: Basic Profile Artifact ID: 1262 Category: <None> Group: <None> Status: Open Priority: 4 Last Modified By: Last Modified: 2005-02-04 15:16:16 Submitted By: Andreas Savva Submit Date: 2005-02-04 15:16:16 Assigned To: &lt;None&gt; File(s): <None> 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.] > Should make WSDM aware about the 'set resource property' issue. > (Provided wants WSDM to be 'aligned' with the OGSA profile.) > Fred is the OGSA-WSDM liaison. 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.
