Subject: Business process definition : questions


I have been looking the ebXML Requirements Specification and the WfMCs
Workflow Reference Model. After studying these documents I read two more
documents about business processes.

ebXML documents:
- The ebXML Requirements Specification version 0.9 can be downloaded from
http://www.ebxml.org/specindex1.htm.
- Business Process Metamodel Specification Version 2.0 can be downloaded
from
http://www.ebxml.org/specindex.htm


WfMC documents:
- The Workflow Reference Model TC00-1003 issue 1.1 can be downloaded from
http://www.aiim.org/wfmc/ (click: Standards -> published docs -> The
Workflow Reference Model TC00-1003).
- Interface 1 - Process Definition Interchange V 1.1 Final
(WfMC-TC-1016-P) can be downloaded from 
http://www.aiim.org/wfmc/ (click: Standards -> published docs -> Interface
1 - Process Definition Interchange V 1.1 Final (WfMC-TC-1016-P) ).


In all these documents there is something about business process
definition.

Pages 21-22 in the ebXML Requirements Specification version 0.9:
"
3.3 Business Process 

The Business Process Project Team detailed requirements and deliverables
will:

* Provide a technical specification for BUSINESS PROCESS DEFINITION
(BPDS), enabling an organization to express its business processes so that
they are understandable by other organizations, thereby enabling
integration of business processes 
"

Page 12 in the Workflow Reference Model TC00-1003 issue 1.1:
"
Process Definition

The PROCESS DEFINITION contains all necessary information about the
process to enable it to be executed by the workflow enactment software.
This includes information about its starting and completion conditions,
constituent activities and rules for navigating between them, user tasks
to be undertaken, references to applications which may to be invoked,
definition of any workflow relevant data which may need to be referenced,
etc.
"


After looking ebXML Requirements Specification and the Workflow Reference
Model I have read something more specific about process definition in two
more documents.

In these documents ebXML and WfMC have defined (Business) Process
Definition.

Page 7 in Interface 1 - Process Definition Interchange V 1.1 Final
(WfMC-TC-1016-P):
"
2.1. Introduction

A Process Definition is defined as:

The representation of a business process in a form that supports automated
manipulation, such as modelling, or enactment by a workflow management
system. The process definition consists of a network of activities and
their relationships, criteria to indicate the start and termination of the
process, and information about the individual activities, such as
participants, associated IT applications and data, etc. (WfMC Glossary -
WfMC-TC-1011)
"

Page 11, lines 294-299, Business Process Project Team, Technical
Specification Document, Draft Version 2.0 6/23/00:
"
Business Process Definition 

A business process is a collection of business transactions between
business partners and/or internal activities within one business. These
transactions and/or activities together support the objective of the
business process. A business process definition specifies the choreography
of business transactions needed to complete a business process. The
internal activities that may also be needed, are outside the scope of the
ebXML business process model.
"


Main question: what the difference between these process definitions?

And then some more questions:
- are these process definitions for different usage?
- is ebXML more to external usage between organisations?
- is wfXML more to internal usage in a single organisation?
