Key member of ebXML MSG TC ・ Jamie 2. General Proceedings (1/2) (1) Main discussion points are examination and confirmation about next version of CPPA specification. There are about 230 issue items (Issue List), and all the items were reviewed. (2) CPPA spec. is closely related to MSG (Messaging service) and BPSS (Business process specification schema). Descriptions of relationship with these specifications are described in CPPA spec. (3) The next official version number of CPPA will be V2.0. Reason: -Version no. of MSG and Registry is V2.0. -There are many changes in next version of CPPA.

This will be proposed to W3C. General Report of the latest OASIS ebXML CPPA F2F Meeting (January , San Francisco in USA) (2/2) 2. General Proceedings (2/2)
4 The Latest Status of OASIS ebXML CPPA TC (CPPA TC Teleconference, April 5, 2002) 1. Coordination with WSDL Karl Best (OASIS) asked CPPA TC to consider what coordination between our activities and W3C activities might be beneficial. Dale noted that we have explicit dependencies on XMLDsig, Xlink (and its dependencies, such as XPath), and of course on XML and XML Schema specifications. No special need for coordination was identified for these dependencies. CPPA TC agreed that it might be beneficial if CPPA and WSDL were in some way coordinated or put together. It was noted that there is a sub team pursuing research on how that integration can occur, and several CPPA members (Kevin, Pallavi, and Dale) participate in the WSDL WG. Arvola also noted that the Architecture WG within the Web Services activity is also relevant to CPPA, and there was agreement that we should monitor developments in that group also. 3. Next F2F meeting ・ Possibly June Schedule of CPPA Spec. ・ Reviewing current draft (V1.11) within CPPA TC members until April 19, 2002 ・ Public review (Supposed to be May, 2002) ・ Submit to OASIS for approval (Supposed to be early June) ・ 90 days Official Review in OASIS organization (Supposed to be July, August, and September)

6 General Explanation of CPPA Specification and related Specifications ・ CPPA (Collaboration-Protocol Profile and Agreement Specification) V1.11 (draft-bpss-example-017) (draft-cpp-example-companyA-017.xml) (draft-cpp-example-companyB-017.xml) (draft-cpa-example-017.xml) ・ MSG (Message Service Specification) V2.0 ・ BPSS (Business Process Specification Schema) V1.02 April 10, 2002 Based on: (1)Relationship between BPSS, CPPA, and MSG (2)Examples of BPSS, CPP/CPA, and MSG Header
7 Business Process and Information Model ebXML Process-Specification Document ebXML CPP/CPA ebXML Business Service Interface Configuration Process-Specification Document and Business Service Interface Configuration Using Business Process Modeling, a user may create a complete Business Process and Information Model. Based on this Business Process and Information Model and using the ebXML Business Process Specification Schema the user will then extract and format the nominal set of elements necessary to configure an ebXML runtime system in order to execute a set of ebXML business transactions. The result is an ebXML Process-Specification Document. Alternatively the ebXML Process-Specification Document may be created directly, without prior explicit business process modeling. An ebXML Process-Specification Document contains the specification of Business Transactions and the choreography of Business Transactions into Business Collaborations. This ebXML Process-Specification Document is then the input to the formation of ebXML Collaboration-Protocol Profiles and Collaboration-Protocol Agreements. These ebXML Collaboration-Protocol Profiles and Collaboration-Protocol Agreements in turn serve as configuration files (e.g. Messaging Header) for ebXML Business Service Interface software.
8 An user create Process-Specification Document supposed to be used some Buyers and Sellers. Usually, Process-Specification Document is created by Service unit. (e.g. each RosettaNet PIP) Process-Specification Document describes choreography of Business Transactions and role of Parties. Creation of Process-Specification Document Creation of CPP(Company A) and CPP(Company B) A buyer creates CPP (Company A) based on ebXML CPPA Specification, In case of Business process scenarios, CPP points Process-Specification Document by URI. (Head of Process- Specification Document and position of Role element) And the buyer describe many CPP information. (ServiceBinding, DeliveryChannel, Transport, DocExchange, Packaging) Also, a Seller create CPP (Company B) like the same way. Creation of CPA between Company A and B In usual case, The buyer creates CPA together with CPP (A) and CPP (B). The relationship between CPA and Process-Specification Document is same as CPP. That is, some URI under ProcessSpecification element and Role element point to suitable position of Process-Specification Document General Procedure to create Process-Specification Document, CPP, and CPA
9 Relationship between Process-Specification Document, CPP, and CPA
10 Modifying Parameters of PSD (Process-Specification Document) based on information in the CPA A Process-Specification Document and CPP/CPA has same kinds of parameters. An example is Security attributes that are counterparts of the attributes of the CPA BusinessProcessSpecification element. When a CPA created, the Parties may decide to accept different value of these parameters. In this case, these parameters shall override the original values expressed in the Process-Specification Document. In this case, overridden Process-Specification Document should be a copy of the original Process- Specification Document. Because the original Process-Specification Document may be used some different parties. original Process-Specification Document Customized Process-Specification Document Public PSD for every party For special parties (e.g. company A,B) Customize CPA (A,B) Copy
11 Examples of Process-Specification Document, CPP, and CPA These examples are supposed to be followings. ・ Binary collaboration between 2 companies. (‘CompanyA’, and ‘CompanyB’) ・ These companies do collaboration using the RosettaNet PIP3A4 as Business Process Scenarios. -PIP3A4 is recognized as ‘Service’ in the view point of BPSS. -PIP3A4 has two business actions. These are recognized as ‘Action’ in the view point of BPSS. ‘Purchase Order Request Action’ and ‘Purchase Order Confirmation Action’.

T07:21:00Z T07:21:00Z - - Example of CPA Document (Company A and B)
24 Explanation of Example of CPA This CPA has two PartyInfo elements. One is information for CompanyA (DUNS ’ ’), the other one is information for CompanyB (DUNS ’ ’). The role of CompanyA is buyer; this is specified by Role element under PartInfo element. The role of CompanyB is seller. [Status element] The value ‘proposed’ means that the status of this CPA is under negotiation between two companies. The other value ‘agreed’ and ‘signed’ are capable. [Start element] ‘ T07:21:00Z’ means that this CPA will be valid from the time of 7:21 am UTC (Coordinated Universal Time) on May 5, [End element] ‘ T07:21:00Z’ means that this CPA will be invalid from the time of 7:21 am UTC (Coordinated Universal Time) on May 5, [ConversationConstraints element] ‘100’ of invocationLimit attribute means that if the number of conversations is reached to 100 times, this CPA is terminated and must be renegotiated. ‘10’ of concurrentConversations attribute means that 10 conversations can be in process at the same time. The meaning of number as the content of this element is number of business transaction (e.g. Purchase order), is not a performance parameter.
25 Relationship between CPA and Messaging Header CPA (A,B) Business Document Message Header Header Envelope Payload Envelope Payload ・ When the Business Document is composed by middleware above the Message Service Interface (MSI), Some parameters are referred and implemented in the Message Header in the Business Document.
