What is punning in Owl type 3?
Use cases of type 3 (annotations/data/object properties) might require some logical consequences. Punning is a simple way to provide for metamodeling that (a) does not require a major change to OWL 1.1 (DL) reasoners and (b) usually seems to satisfy the semantic requirements.
What is the Association class in owl?
The Association Class allows a modeler to define a relation as an association and reify it simultaneously. This is convenient when one wants to model attributes of relations themselves. Class and Object Property punning may support the same modeling need for OWL 1.1.
How to make owl more meaningful in DL?
Note that, in order to give some meaningful semantics to OWL 1.1 DL, you need a strict separation between the object and the data domain (otherwise the logic becomes really horrible). Punning between data and object properties is an easy solution to this problem.
