Jürgen Jung Where it Began: ECOMOD ECOMOD – E-Commerce Modelling Support for developping e-commerce related applications  Basing on a company‘s strategy  Supported by business process models StrategyE-Commerce Application

Jürgen Jung Developping Applications on the Basis of Process Models Programming environment  Implementation is done by programmers  Business logic is implemented using a programming language  Components, frameworks or class libraries may be reused Process-oriented systems  Examples: - Workflow Management System - BPEL4WS-Engine (Business Process Execution Language for Web Services)  Provide similar concepts like business process models - Control flow - (Special) Resources

Jürgen Jung Process Models and Workflow Schemata Process and workflow are similar abstractions  Focus on control flow Process models  Provide the notion of - Resources - Information Objects  Language used in our context: MEMO-OrgML - MEMO: Multiperspective Enterprise Modelling - OrgML: Organisation Modelling Language Workflow  Focusses on tasks executed by IT-resources (especially a Workflow Management System)  Standardised specification Language: XPDL - XML Process Definition Language

Jürgen Jung Open Research Questions Identification of common features of (business) process modelling languages Classes of similar process modelling languages (sharing common features) Kinds of deltas, e.g.  Adding syntactic features  Defining semantics, e.g. - Operational semantics Are current meta-modelling tools capable of providing all necessary features?
