[VK] Clarification: What I propose to standardize is not (a) how to represent
these proofs; or (b) normalization of lemma generation.

All I am proposing is a standardized format to "report" these things.
As more results emerge from the experiementation, they can easily be
represented and reported in a standardized format. This is along this lines
of the PML work by Deborah customized for OWL 1.1

BTW, would be very interested in initial results of these field trials where
available.

[VK] See my clarification in the e-mail before. A standardized way of reporting
proofs will be a very useful feature for tool and application interoperability
in the context of ontology building.
