Notes of ebCore TC CPPA SC meeting (2009-10-20) Present: Dale Moberg Pim van der Eijk Pete Wenzel Regrets: Sander Fieten Discussion: Issue EBCORE-1: CPA had a global value for all asynchronous signal messages, based on the assumption that signals would have share the same value in a CPA, unlike business messages. The issue arose because even in CPA 2.0 this is not true: different action bindings can have different values for AckSignatureRequested, so if acknowledgments are asynchronous, some are to be signed and others not. The proposed solution from the email archives was to have a new subelement that could be added to an action binding to specify a channel for signals related to that action. In the discussion we talked about an even more flexible mechanism, to have a new repeatable element that can be used to define channels for specific types of messages related to the business message. If the "type" is expressed as an attribute, we could use some predefined values for this attribute to specify separate channels for all sorts of WS-* signals (acknowledgments, SOAP faults) and ebMS signals (errors, receipts). We could use the convention of predefined URIs for synchronous response (anonymous EPR) as an alternative to syncReplyMode. Other topics: Dale and Pete will post their (overlapping) issue to JIRA. Next call two weeks from now.
