You can pun in OWL 2 Full and DL as both a class and object property - it's briefly mentioned in the documentation here at the bottom of the examples: https://www.w3.org/TR/owl2-new-features/#F12:_Punning I know of one organization that will pun classes and datatype properties (no possible in OWL DL) for convenience of modeling, but when I asked around at my workplace no-one else had heard of people punning in that way, so I've always assumed it's pretty uncommon and I don't think that tooling tends to particularly like when you do it. That's about all I know about it. There is a working draft for OWL 2 online that goes into it more (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.448.2097&rep=rep1&type=pdf) but those parts seem to have been cut from the final documentation so be aware of that.
