===='''OASIS; ebXML Business Process Specification'''====
* ebxmlbp-v2.0.4-Spec-os-en.pdf
* eBusiness eXtensible Markup Language (ebXML) defines a standard language by which business systems may be configured to support execution of Business Collaborations consisting of Business Transactions
*  The ebBP technical specification supports the specification of Business Transactions and the choreography of Business Transactions into Business Collaborations
* A '''Choreography''' is an ordering of Business Activities within a Business Collaboration
* The choreography is specified in terms of Business States, and transitions between those Business States.
* When a transition is validated: it does not mean that the target Business Activity would start immediately, it means that the Business Activity is “enabled” and the initiating party may now send the request whenever appropriate, provided that it remains within the  TimeToPerform of the Binary (Business) Collaboration
* It is merely the execution of the backend systems, which instruct the BSI (Business Service Interface) to send or receive messages that advance the state of a collaboration
* There is no execution engine associated to the collaboration itself. 
* The Business Collaboration is either in the state of performing a given Business Activity (or multiple concurrent Business Activities) or waiting to start a Business Activity, unless it has reached a completion state
* Once a Business Activity completes a transition from this Business Activity, it navigates to another Business Activity
* A business message initiates a Business Collaboration or advances its state
