2. Applicability of Schema Integration
Towards Semantic Integration of XML-based Business Process Models 13.04.2005Slide 8
Schema Integration Methodology
• Schema conflicts
• Similarity relations between schema concepts
• Disjointness
• Intersection
• Subset
• Equality
• Criteria for global integrated schema (Batini et al. 1986)
• Completeness
• Minimality
• Understandability

3. Ingredients of Metamodel Integration
Towards Semantic Integration of XML-based Business Process Models 13.04.2005Slide 13
Keep the balance
• Bottom-up schema integration
• Required concepts and relationships
• Generalisation of concepts
• Top-down domain modelling
• Identify mappings between concepts
• Consolidation of concepts

4. Outlook
Towards Semantic Integration of XML-based Business Process Models 13.04.2005Slide 15
Next steps
• Definition of engineering process for metamodel integration reflecting
• Canonical representation of concepts (ontology-based)
• Complex semantic relationships
• XML design guidelines
• Case study on BPM standard integration
• Test for applicability in other domains

Effekte der Standardisierung von Austauchformaten
• Pragmatischer Effekt: Austausch von Modellen
• Ökonomischer Effekt: Reduzierter Lock-In, mehr Wettbewerb
• Konzeptioneller Effekt: Konsolidation der Konzepte
