1. Understanding MFI? More mapping requirements

2. Commentary
This presentation was prepared to inform discussion at the 2008 WG2 Meeting in Sydney. The purpose was to set out additional requirements that the mapping module needs to address.
These are the models that the editor of referenced in his presentation on 25 June 2009 during the 2009 WG2 Meeting in Jeju.

3. Three more ‘Level 1’ data models
(b)
(a)
All same universe of discourse
but different
levels of
abstraction
(c)
Note: (a) Is a ‘bad’ model but is typical of the sort of model developed by new modellers

4. Mapping (a) to (b) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of DEPOT maps to an instance of SUPPLY UNIT in (b)
(b)
Each instance of the relationship from DEPOT to SUB-DEPOT maps to an instance of the relationship from SUPPLY UNIT to UNIT in (b)
Each instance of SUB-DEPOT maps to an instance of SUPPLY UNIT in (b)

5. Mapping (a) to (b) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of SUB-DEPOT maps to an instance of SUPPLY UNIT in (b)
Each instance of SUPPLY UNIT maps to an instance of SUPPLY UNIT in (b)
Each instance of the relationship from SUB-DEPOT to SUPPLY UNIT maps to an instance of the relationship from SUPPLY UNIT to UNIT in (b)

6. Mapping (a) to (b) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of UNIT maps to an instance of UNIT in (b)
Each instance of SUPPLY UNIT maps to an instance of SUPPLY UNIT in (b)
For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of the relationship from SUPPLY UNIT to UNIT maps to an instance of the relationship from SUPPLY UNIT to UNIT in (b)

7. Mapping (b) to (c) For the MODEL INSTANCE (b):
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that has any designation
(c)
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit”
Each instance of the relationship from SUPPLY UNIT to UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT UNIT ASSOCIATION and its associated relationships to the two UNIT instances
For the MODEL INSTANCE (b):

8. Mapping (a) to (c) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit – Sub-Depot”
(c)
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit – Depot”
(a)
For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of the relationship from SUPPLY UNIT to UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT UNIT ASSOCIATION and its associated relationships to the two UNIT instances

9. Mapping (a) to (c) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit – Supply Unit”
(c)
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit – Sub-Depot”
(a)
For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of the relationship from SUPPLY UNIT to UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT UNIT ASSOCIATION and its associated relationships to the two UNIT instances

10. Mapping (a) to (c) For this MODEL COMPONENT SET of MODEL INSTANCE (a):
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that has any designation
(c)
Each instance of SUPPLY UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT that is described by an instance of UNIT TYPE that is designated as a “Supply Unit – Supply Unit”
(a)
Each instance of the relationship from SUPPLY UNIT to UNIT maps to a MODEL COMPONENT SET in (b) that consists of an instance of UNIT UNIT ASSOCIATION and its associated relationships to the two UNIT instances
For this MODEL COMPONENT SET of MODEL INSTANCE (a):
