  7. Mapping example #1 Object Class to Entity Type Object Class to Entity Type mapping PRODUCT product-code product-description Object Class to Entity Type Semantically Equivalent Product code : String description : String

  8. Mapping example #2 Supplier ProductSupplier • supplies 1..* 0..* number: String name: String address: Address startDate: Date rating: Integer Many-to-many association replaced by an intersection entity type Object Class to Entity Type Object Class to Entity Type Semantically Equivalent PRODUCT product-code product-description SUPPLIER PRODUCT-SUPPLIER supplier-number Product supplied-by acts-as product-code (FK) supplier-number (FK) supplier-name supplier-address code : String description : String P product-supplier-start-date product-supplier-rating

  9. Mapping example #3 EXTERNAL CUSTOMER DEPARTMENT placer of ORDER (m) number (m) name (m) address (m) name placed by ExternalCustomer Order (m) number (m) date number: String name: String address: Address number: String startDate: Date placer of placed by Object Class to Entity Type Exclusive Arc replaced by Sub-classes Object Class to Entity Type Semantically Equivalent DepartmentalOrder ExternalOrder • places 1..1 0..* Department name : String • places 1..1 0..*

  10. Mapping example #4 FULFILL ORDER ISSUE INVOICE RECORD PAYMENT Process amalgamation Object Class to Entity Type Process decomposed Object Class to Entity Type Object Class to Entity Type Semantically Equivalent Object Class to Entity Type Semantically Equivalent CHECK ORDER PICK GOODS DESPATCH GOODS HANDLE PAYMENT Start Stop

  11. Mapping example #5 Order Received Payment Recorded FULFIL ORDER ISSUE INVOICE RECORD PAYMENT Sequence dependency replacement Object Class to Entity Type Semantically Similar Object Class to Entity Type Order Received Invoice Issued FULFIL ORDER ISSUE INVOICE Payment Received Payment Recorded RECORD PAYMENT

  12. Mapping example #6 Ontology A Scotch Whisky Single Scotch Whisky Object Class to Entity Type Semantically Equivalent Concept Union Blended Scotch Whisky Ontology B

  13. Mapping example #7 Ontology A axiom1: “Scotch whisky is whisky made in Scotland. axiom2: “Scotch whisky is a kind of whisky.” Object Class to Entity Type Semantically Equivalent Concept Intersection axiom3: “Scotch whisky is made in Scotland.” Ontology B

  14. Where we agree • The metaclasses (and their names) - generally • The attributes (and their names) - generally • The associations (and their multiplicities and names)

  15. Where we disagree • Whether to use separators or camel case for names. (recommendation: upper camel case for metaclasses, lower camel case for attributes, associations, etc) • How to document associations in the text: • with one reference? • with two references? • (CA prefers associations documented separately) (recommendation: two references) • How and where to explain the relationship to MDR-3. • Okabe-san is not too happy with “model mapping”. • Whether a model must have an IRI.

  16. Any questions?
