Dimensions seem to be objective, perspectives subjective
Subjective uncertainty is likely caused by 'lack of knowledge of what is there'
which comes across as a 'weakness' of the ontology (cause making
knowledge explicit is the purpose of the ontology isnt it) (03)
I wonder if we should also add 'requirements' to the framework (04)
