  1. Introduction to Business Process Modeling Language/Notation (BPML/BPMN) Sharon L. Hanger Booz | Allen | Hamilton XML.gov Working Group Washington, DC February 18, 2004

  2. Overview • Introduction • BPML and BPMN • Questions

  3. Introduction

  4. BPML provides an abstract model and XML syntax for expressing executable business processes and supporting entities • Processes include but are not limited to, the definition of enterprise business processes, the definition of complex Web services, and the definition of multi-party collaborations. • A fully compliant implementation of BPML 1.0 must support the following features • The BPML specification was originally authored by BPMI.org • The most current public version is Version (November 2002) which can be downloaded from http://www.Bpmi.org Source BPML Specification, BPMI.org

  5. The following XML example represents an inventory checking process Source BPMI.org 2002

  6. BPMN is a draft specification for the graphical notation of BPML and BPEL4WS Source BPMI.org 2003

  7. BPML has unique features for modeling complex business processes • End-to-End Flow Modeling • Flow-Control/Data-Flow Separate • Product Consume Messaging • Dynamic Control Flow • Transparent Persistence • Embedded Business Rules • Nested Processes • Distributed Transactions • Process Oriented Exception Handling • Underlying Mathematical Model – Pi Calculus

  8. While BPML and BPEL4WS have many similarities, they also have distinct differences • Some facts about BPML and BPEL4WS • BPML is a strict superset of BPEL4WS • BPML and BPEL4WS share an identical set of idioms and similar syntaxes as the basis of convergence • BPML provides a rich and mature language for expressing both simple and complex business processes • BPML and BPEL4WS are both block-structured languages, with the addition of nested processes in BPML • BPML is based on a logical process model that can fully express concurrent, repeating, and dynamic tasks • BPML builds on the foundation of WSCI for expressing public interfaces and choreographies
