Subject: RE: [ws-rx] Issue 28: MakeConnection preconditions are unclear


In the proposal we made for PR001 I don’t believe the below is an issue. The expected setup for MakeConection is defined.

 

I agree that if we close PR001 with no action that the current spec will need to be changed to address this problem.

Subject: [ws-rx] New issue: MakeConnection preconditions are unclear

 

MakeConnection as defined today relies on the RM Anonymous URI template.  The spec does not adequately specify the preconditions necessary for the exchange to be successful.

 

Prior to a MakeConnection message, do both the client and the server have to be in possession of a correctly constructed instance of the RM anon URI template?  Of an EPR using this template?  The example messages invent a subscription operation in step 1, which indicates that the precise URI and the intent to enable MakeConnection must be negotiated between the RMD and RMS out of band, yet nowhere are these preconditions enumerated.  The RM protocol preconditions only list an EPR as a precondition, not the precise form of that EPR, and any intention that buffering of messages should be engaged.  What happens if a client does a MakeConnection without all preconditions being satisfied also appears to be underspecified.
