Challenges in Using OpenTheory to Transport Harrison's HOL Model from HOL Light to HOL4

7 pages•Published: May 26, 2013

Abstract

OpenTheory is being used for the first time (in work to be described at ITP 2013) as a tool in a larger project, as opposed to in an example demonstrating OpenTheory's capability. The tool works, demonstrating its viability. But it does not work completely smoothly, because the use case is somewhat at odds with OpenTheory's primary design goals. In this extended abstract, we explore the tensions between the goals that OpenTheory-like systems might have, and question the relative importance of various kinds of use. My hope is that describing issues arising from work in progress will stimulate fruitful discussion relevant to the development of proof exchange systems.

Keyphrases: higher-order logic, HOL Light, HOL4, OpenTheory, proof transport, simple type theory
