Introduction: Problem

| Business Process Management (BPM)| Design and Modeling | Execution via workflow engine | Operation and Monitoring| Evaluation and Optimization

| Classification of BPM levels (Gadatsch, 2005)| Strategic level| Functional level| Operational level

| Problem definition | Ontology based workflow model

Introduction: History

| Strategic level| Using specific procedure in designing processes (e.g. V-model)

| Functional level| Moving from a cognitive model to a computational model (e.g. business

processes)| Involving foundational ontology (e.g. DOLCE, DDPO module)

| Operational level| Business process execution (e.g. BPEL, WSDL)

Hypothesis

| MDA approach | OMG MOF – defines the metadata architecture for MDA| OMG ODM – standard model for model driven ontology development

| Metamodels| OWL| BPEL| WSDL

| Transformations| Problem: lack of ontologically specified knowledge about business

processes

Strategy

| Ontology reengineering| SE & KE | Design Patterns (SE) & Ontology Patterns (KE)| Classification of Ontology Patterns:

| Content pattern

| Structural pattern (Architectural + Logical)

| LexicoSyntactic pattern

| Reasoning pattern

| Presentation pattern (Naming + Annotation)

| Correspondance pattern (Reengineering + Alignment)

| Reenginering ODP
