As an implementer, specially given the approach of the majority of folks is to err on the generic direction, I think the formalism will be very helpful. The formalism will be much more clear than OWL in form of things like boundary conditions for the implementers.
16:18:08 [GK]
@Paolo: if OWL can capture the semantics, then there is no (necessary) difference, IMO,

...owl DL was not for designed for semantics of programming language
16:19:13 [GK]
OWL *is* a DL language; mapping DL to OWL is misleading, IMO
16:19:24 [Reza_BFar_]
Please remember that implementers will need to tie Query and Model together with some implementation (implement search algorithms, etc.) and having a formal Model provides boundary conditions (for example, what search algorithms may not be admissible, etc. based on the mathematical formalism)
