ISSUE-85: remove someValues from restriction on hassubsystem
Subsystem
remove someValues from restriction on hassubsystem
- State:
- CLOSED
- Product:
- Semantic Sensor Network Ontology
- Raised by:
- Kerry Taylor

- Description:
- Currently, a ssn:System has both a someValues from and an AllValues from restriction on hasSubSystem.System to describe a recursive part-of structure. Clearly the existential (someValuesFrom) restriction should not be there as surely we allow a finite system with a terminating sytems that has no subsystem. Removing the restiction would be backwards- compatible as it is weaker, and almost certainly is the way System has been used in practice anyway.
