Subject: Identifying WS-BaseNotification dependencies on WSRF
In order to clarify issue WSN2.2 David Hull and myself reviewed WS-BaseNotification to determine the points at which WS-BN currently depends upon the WSRF specifications. Some of these points are already being discussed in other email threads and their discussion should continue in those threads. Related existing issues are identified where possible. Section 3.1: Notify message may follow implied resource pattern. Section 4: First sentence implies resource properties must be supported. Section 4.1: Indicates the required messages of WSRF-RP must be exposed, the optional messages may be exposed. Defines a property document where the spec does not indicate whether the properties are writable, but they appear as if they are read-only. Section 4.2: The Subscribe message has 2 fields of type QueryExpression as defined in WSRF-RP. The fields are Precondition and Selector. It is not clear that these fields have the same type of expression as the operation QueryResourceProperties defined in WSRF-RP. There is a statement that the Subscribe message must follow the implied resource pattern. " ": The description of InitialTerminationTime talks about the property TerminationTime (presumably from WSRF-RL) implying a dependency. " ": Both the request and response talk about a subscription resource. Also the subscribe response message contains an endpoint reference specifically having reference properties that include a subscription identifier. This implies a dependency on WSRF-RP. Section 4.3: The GetCurrentMessage message must follow the implied resource pattern. Section 5: SubscriptionManager follows the implied resource pattern. It must support required WSRF-RP messages and may support optional WSRF-RP messages. It must support both immediate and scheduled destruction from WSRF-RL. (issue WSN2.18 is part of this) Section 5.1: In addition to the properties defined in WSRF-RL, additional properties are defined. The properties Precondition and Selector require the use of QueryExpressionType as defined in WSRF-RP. Only the property CreationTime is explicitly read-only. (relates to issue WSN2.7 and WSN2.20 and WSN4.14) Section 5.2: Pause message must follow implied resource pattern. Statements referring to TerminationTime from WSRF-RL. Section 5.2: Resume message must follow implied resource pattern. In general, it is not clear what is intended in the several places that indicate an implementation must/may follow the implied resource pattern. This becomes even more true as the specs move towards standardization as the current plan is not to publish the state paper as a normative part of the standards. David Hull and Bryan Murray
