This Galois Tech Talk, the first for 2009, was our very own Joe Hurd talking about package management for theories. You can read the slides
Interactive theorem has grown beyond toy examples in mathematics and program verification, as demonstrated by recent successes such as the Gonthier's formal proof of the four colour theorem and Leroy's verified compiler from a realistic subset of C into PowerPC assembly code. As the construction of large programs led to the development of software engineering techniques, there is now a need for theory engineering techniques to support these major verification efforts.In this talk I will present the OpenTheory project, which has defined a simple 'article' format to represent theories of higher order logic. Theories in article format can be written by one higher order logic theorem prover, compressed by a standalone tool, stored and read by a different theorem prover. Articles naturally support theory interpretations, which leads to more efficient developments of standard theories, and also provides one approach to handling difficult constructs such as monads without extending the underlying logic. Finally, the grand vision of the OpenTheory article repository is painted, with fully automatic installation and dependency resolution.
