This package provides ebXML CPP and ebXML CPA building blocks required for creating ebXML CPP's and ebXML CPA's for ebXML systems that implement the Universal Business Process for the Procurement context with the Universal Business Language (UBL 1.0).
2. ebXML Collaboration Protocol Profile and Agreements
4.1. Building block 1: ebCPPA CollaborationRole element
4.2. Building block 2 and 3: ebCPPA SimplePart and ebCPPA Packaging elements
5. Used CPA template to produce a sample CPA for each Universal Business Process
6. Results (ebCPPA building blocks and sample CPA's)
This package includes the ebCPPA building blocks for procurement Universal Business Processes. This package introduces the ebXML Collaboration Protocol Agreement and the relationship between ebXML Business Processes and ebXML Collaboration Protocol Profiles and Agreements. The ebCPPA building blocks, namely ebXML CPPA CollaborationRole, ebXML CPPA SimplePart, and ebXML CPPA Packaging elements are building blocks that are provided by this package. This package provides a sample CPA for each Universal Business Process. The CPA template, and certificates which was used is provided. Finally all produced files are presented. The document closes with open issues, references and notices.
This package uses the ebXML Collaboration Protocol Profile and Agreement Specification version 2.0.
An ebXML Collaboration Protocol Agreement (CPA) is an agreement between two trading partners
of how to technically implement a collaborative business process.
A typical ebXML CPA document includes the following information:
This document includes the required ebXML CPPA building blocks based on the Universal Business Process version 1.0. This includes the CollaborationRole elements for each role participating in the Business Collaboration and, further, this includes the Packaging information.
The ebXML Business Process Specification provides the means to specify collaborative business processes
between two or more parties. An ebBP definition does not list parties but lists "roles" that take action
in the collaboration. Collaborative business processes are a choreography of individual business
transactions. ebBP provides a standardized set of common business transaction patterns (Commercial Transaction,
Notification, Request-Response to name just a few). Each business transaction lists the business documents
(for example by referencing a UBL invoice) that are exchanged during its execution but also the business signals
which are exchanged during its execution. Business signals are used to align the collaborative state between the trading
partners. The ebBP further provides the means to set business related quality of service attributes, such as
request for confidentiality, request for non repudiation, request for guaranteed delivery and more.
An ebXML CPA binds two trading partners to the roles participating in a collaborative business process.
It further provides all the required technical information of how to execute the collaborative business
process, targeting messaging. The CPA lists all business documents as well as all business signals that can
be exchanged. The CPA further lists the Packaging of these business documents and business signals.
Information given in an ebBP definition is found again in the ebXML CPA.
This package provides all the ebXML CPP or CPA building blocks of the Universal Business Processes that are required to create an ebXML CPA for two trading partners.
The building blocks are the ebXML CPPA CollaborationRole, SimplePart, and Packaging elements.
The ebXML CPPA CollaborationRole element references the ebBP definition and derives the "Service" name and type which are used for ebXML Messaging. Further, the ebXML CPPA CollaborationRole lists all business document and business signal exchange for a given Role in the ebBP definition. Each business document and business signal will receive a derived "Action" name.
The ebXML CPPA SimplePart and Packaging elements provide packaging information for each business document and business signal. This information can be used by a messaging system to package the ebXML Messages based on ebXML Messaging Service Specification version 2.0.
For the production of valid sample CPA for each Universal Business Process an ebXML CPA template was used. The ebXML CPA template misses CollborationRole's, SimplePart's and Packaging elements. The CPA template lists as the first party Coronation and as the second party Gnaraloo (named after two places in Western Australia). The CPA template is
- CPA template
XML digital signature and SSL authentication is used in the CPA. The CPA template already includes the public certificates. The CPA template lists a public certificate for signing and as SSL server certificate but in fact the same certificate is used for both tasks. In this example, self signed certificates must be trusted. In order to test the sample CPA's the private certificates are also provided here.
- Private x509 certificate for Coronation..
- Private x509 certificate for Gnaraloo.
The password for each certificate is "cyclone" without quotes.
For each Universal Business Process a ebCPPA building blocks file, a sample ebXML CPA, and the ebXML CPA's HTML view was produced.
Some issues need future resolution.
