Submission Guidelines


Please send your submission via this web page.

The submission must follow the following Isabelle style rules. For additional guidelines on Isabelle proofs, also see the this guide (feel free to follow all of these; only the below are mandatory). Technical details about the submission process and the format of the submission are explained on the submission site.

  • No use of the commands sorry or back.
  • Instantiations must not use Isabelle-generated names such as xa — use Isar or rename_tac to avoid such names.
  • No use of the command smt. The result of this command depends on external tools that are not under our control and may stop working in the future.
  • apply scripts should be indented by subgoal as in the Isabelle distribution. If an apply command is applied to a state with n+1 subgoals, it must be indented by n spaces relative to the first apply in the sequence.
  • Only named lemmas should carry attributes such as [simp].
  • We prefer structured Isar proofs over apply style, but do not mandate them.
  • If there are proof steps that take significant time, i.e. longer than roughly 1 min, please add a short comment to that step, so maintainers will know what to expect.

It is possible and encouraged to build on other archive entries in your submission. There is a standardised way to refer to other AFP entries in your theories.

Your submission will be refereed and you will receive notification as soon as possible. If accepted, you must agree to maintain your archive entry or nominate someone else to maintain it. The Isabelle development team will assist with maintenance, but it does not have the resources to fully maintain the complete archive.
