ebXML Registry

• Central storage of business information, e.g.
  business process descriptions, XML schemas, CPPs,
  etc.
• CPP (Collaboration Protocol Profile) - a profile
  filed with a Registry by a business wishing to
  engage in ebXML transactions. The CPP will
  specify some Business Processes of the business,
  as well as some Business Service Interfaces it
  supports.

Registration/Implementation

• A company will access the Registry to examine
  existing Business Processes and Business
  Scenarios
• A company will build and publish its
  Collaboration Protocol Profile (CPP), including
  its Business Process Information

Discovery

• In this phase a company will use the Registry to
  discover business processes and interfaces
  published by other trading partners.
• A company will generate and send a Collaborative
  Partner Agreement (CPA) to a trading partner
• CPA is a reflection/intersection of both
  companies CPPs.
• CPA contains information about messaging
  requirements for transactions, the conversations
  that take place in a collaborative business
  process, contingency plans, and security-related
  requirements.

7
Negotiation

• The resulting CPA is submitted to a trading
  partner and is used to configure the runtime
  systems of both companies.
• After the trading partner accepts the CPA, both
  companies are ready to engage in e-business using
  ebXML
• The transactions consist of ebXML messages, which
  are sent over the standard ebXML Messaging
  Service
• ebXML MS utilizes SOAP and HTTP (it also allows
