Re: [wsdm] Weather station WSDL and RequestProcessingDigest comments

["Hideharu Kato" <hideharu@sdl.hitachi.co.jp>]

It is unclear to me whether WeatherStation is a WS-Resource or just a Web
service endpoint.

I don't think that the operation which causes the
RequestProcessingNotification is GetRP().

I think WeatherStation Web service is just a "Web servcie" not a
"WS-Resource".
The GetRP() operation is the operation WS-Resources expose.
I don't believe that MOWS restricts its target only to WS-Resources.

I know that in-band case is also possible in MOWS.
But even if in such a case, ManageableEndpoint(WeatherStation) has
some business operations(functional operations) like a
GetCurrentTemperature().
This operation causes the RequestProcessingState event.

The FCCID is a property of WeatherStation Web service,
but it is not necessary to be a Resource Property (defined in WSRF) of
WeatherStation service.

In the case of in-band, WeatherStation itself is the ManageabilityEndpoint,
so WeatherStation(ManageabilityEndpoint) has stateful resource
which represents its own state.
In this case, WeatherStation is a "WS-Resource".

In the case of out-band, another Web service endpoint (MOWS service) is
the ManageabilityEndpoint of WeatherStation.
So, MOWS service(ManageabilityEndpoint) has a stateful resource
which represents the state of WeatherStation.
In this case, FCCID is a Resource Property of MOWS service(stateful
resource).
The GetRP() operation is exposed by MOWS service
in order for requestor(manageability consumer) to get FCCID of
WeatherStation.
So, WeatherStation is not necessary to be a WS-Resource nor to expose
GetRP().

Anyway I believe that WSDL of WeatherStation Web service(functional
porttype)should be provided before interop.
