An ontology of Does would encourage attention to this facet of a system. For
example, lots of confusion currently exists regarding function, behavior,
capability (to, for, of) output and effect (on context). More formally, an
ontology containing the Boolean operators and relationships would be as useful
as one containing plain and opaque arrowheads, diamonds, etc.
Overall an ontology of the Does things would encourage more careful usage of
class vs. type.
Make sense? (01)
