Deletes a single relation from the KBMS.
A relation is equivalent to a single value of a slot of a frame in
a frame-based KBMS.
- The clause to be deleted.
(:DELETE (Color MyFrog Green))
(:DELETE (Creates Microsoft RobustSoftware))
Succeeds if the relation exists in the KB.
Fails if the relation does not exist in the KB.
This command should be used with care. Even though relation values are
deleted, inferences made from those values are not deleted. Algernon does
not currently support non-monotonic reasoning.
