In previous work, we translated the mathematical library of the IMPS system (at danger of being lost due to the system no longer actively developed) to OMDoc and partially verify the result within the MMT system against an implementation of the underlying logic of IMPS.
However, so far we only include proof scripts as informal (not machine-checkable) information in our translation. Hence, our goal now is to extend our implementation of the translation to also include as much formal information as possible about the IMPS proof commands, user-defined macetes and their combination language, with the hope of being able to also formally verify (parts of) the translated proofs via MMT.
