Subject: Identifying WS-Resources: ReferenceProperties or ReferenceParameters?
Hi Steve I copied and pasted into a new thread since it looks this topic belongs on its own. Steve Graham wrote: Isn't this then in contradiction with the new WS-Addressing spec that suggests "A consuming application should assume that different XML schema, WSDL definitions and policies apply to endpoint references whose address or reference properties differ"? The way it is used now, we have different referenceproperties associated with the same schema, wsdl and policy. I concluded from the above statement that referenceproperties are used to allow the use of the same address by many different services (endpoints) (potentially different in schema, wsdl or policy). An example is a load balancing service that is a front for a server farm where different requests are routed to different machines depending on their policy requirements for example. Now where does the reference parameters come in. The spec says [reference parameters] : xs:any (0..unbounded). A reference may contain a number of individual parameters which are associated with the endpoint to facilitate a particular interaction Each enpoint in the server farm can additionally use reference parameters to identify/disabiguatre WS-resources (subscriptions for example). So we have some sort of two level referencing. The first allows the use of one adress by many endpoints and the second allows the use of one endpoint by many ws-resources. Abdeslem /////////////// |
