  1. Experiences Formalizing OAG eBusiness Models in OWL, Two perspectives- perspective 1: manual analysis Evan K Wallace Manufacturing Systems Integration Division

  2. Outline • Two efforts • AMIS description • OAGIS description • OAGIS LIM • UML -> OWL mapping rules • Mapping issues and examples

  3. Two Different projects with two approaches • B2B Testbed: • Automated Methods for Integrating Systems (AMIS): OAGIS XML Schema OWL OAGIS XML Schema UML™ OWL

  5. AMIS approach • Ontology Extraction: • Capture Local Interaction and Engineered Interface Models of existing software/standards • Specify Joint Action Model for the integration • Semantic Mapping: • Map the Joint Action Model to the Local Interaction Models of the components • Connector Transformation: • Generate Wrappers or Interceptors to link the real engineered interfaces

  10. What is OAGIS? • Open Applications Group Integration Specification • OAGi [1] formed in late ’94 • Initially composed of primarily of ERP system vendors to enable integration among such systems [1] www.openapplications.org

  11. Interoperability and standards • What is interoperability? • Why participate in standards development?

  12. What were the drivers for OAGIS? • ERP vendor independence • Middleware independence • Business process independence Leading to a structure with BODs, Nouns and Verbs

  13. Verbs Acknowledge Add Cancel Change List Load Process Receive … Nouns BillOfMaterial ElectronicCatalog Invoice Party Quote RequestForQuote Shipment ShipmentSchedule … BOD Components Resources: Components, Fields, and Enums

  15. OAGIS LIM components (see model slides) • Parties • Transactions • Documents • Items • Shipments • Orders • RFQ

  16. UML Package -> owl:Ontology <<import>> -> owl:import UML Class -> owl:Class UML Attribute -> owl:DatatypeProperty or owl:ObjectProperty UML Association –> one or more object properties and class restrictions on cardinality Some Rules for mapping UML to OWL DL
