Subject: [ebxml-cppa] RE: [wssqop-discuss] CPPA ppt slides - WSDL mapping forCPP/CPA
Hi Dale, Thanks for sending us your prsentation in advance. Some questions/comments: 1) Has the ebXML Messaging/CPP/A TCs decided if and when they will support WSDL mapping for CPP/A? I consider CPP/CPA to be a super-set of WSDL since WSDL provides binding and service information while CPP additionally provides information about the participating web service parties (e.g., role of an organization) in context of a particular service as well error handling and other failure scenarios. 2) Also, has any decision been made about creating WSDL extension elements that reference CPA document? It would be great if WSDL mapping for ebXML CPP/CPA is supported in ebXML v3. However, I understand that a dependency on a more complete WSDL v. 1.2 spec may be a factor in including WSDL support in v3. The reason of my inquiry is the following. If/when ebXML Messaging decides to support SOAP message-level security using OASIS WSS (e.g., for carrying encrypted and signed payloads and to carry SAML Tokens) and if/when ebXML CPA documents can be referenced via WSDL documents, I think we may have a subset of the solution required for WSDL-centric security policy managment for OASIS WSS message security features. However, it is desirable to support interoperable security policies for all OASIS WSS features, not just a subset. Lastly, my sense is that such future standards work may require some consolidation in terms of development such that it could be re-used in various standards (and most importantly non-ebXML web services applications that may use WSS). thanks, Zahid Ahmed Commerce One, Inc. -----Original Message----- From: Dale Moberg [mailto:dmoberg@cyclonecommerce.com] Sent: Tuesday, October 22, 2002 11:25 AM To: Tim Moses; WSS QoP Subject: [wssqop-discuss] CPPA ppt slides Hi, I put a ppt for ebXML CPPA with some general introductory slides taken from previous presentations, which is then followed by a drilldown on how capabilities and agreements concerning message level envelopes (for data confidentiality) are captured in CPA 2.0. Other security features-- digital signature, transport security, etc-- are captured in analogous ways. There are some other aspects in the packaging that would reflect on-the-wire aspects of how the security features are realized that I did not go into in the ppt but can be considered and discussed tomorrow. I put the file at the following URL http://www.oasis-open.org/committees/ebxml-cppa/documents/WSSQOP&CPPA.pp t and you can browse it tomorrow on the call. Bye, Dale Moberg
