Making PVS Accessible to Generic Services by Interpretation in a Universal Format

PVS is one of the most powerful proof assistant systems and its libraries of formalized mathematics are among the most comprehensive albeit under-appreciated ones. A characteristic feature of PVS is the use of a very rich mathematical and logical foundation, including e.g., record types, undecidable subtyping, and a deep integration of decision procedures. That makes it particularly difficult to develop integrations of PVS with other systems such as other reasoning tools or library management periphery. This paper presents a translation of PVS and its libraries to the OMDoc/MMT framework that preserves the logical semantics and notations but makes further processing easy for third-party tools. OMDoc/MMT is a framework for formal knowledge that abstracts from logical foundations and concrete syntax to provide a universal representation format for formal libraries and interface layer for machine support. Our translation allows instantiating generic OMDoc/MMT-level tool support for the PVS library and enables future translations to libraries of other systems.
