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
Opened on:
2016-11-07
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.
