[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

[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.
