Isabelle/DOF: Document Preparation Setup

Isabelle/DOF is a novel Document Ontology Framework on top of Isabelle. Isabelle/DOF allows for both conventional typesetting and formal development. The manual for Isabelle/DOF 1.3.0/Isabelle2021-1 is available online.

Pre-requisites

Isabelle/DOF has three major prerequisites:

• Isabelle: Isabelle/DOF requires Isabelle 2022. Please download the Isabelle 2022 distribution for your operating system from the Isabelle website.
• AFP: Isabelle/DOF requires several entries from the Archive of Formal Proofs (AFP). Please install the AFP following the instructions given at https://www.isa-afp.org/using.html.
• LaTeX: Isabelle/DOF requires a modern LaTeX installation, i.e., at least TeX Live 2022 with all available updates applied.

Installation

Isabelle/DOF is provided as an Isabelle component. After installing the prerequisites, change into the directory containing Isabelle/DOF (this should be the directory containing this README.md file) and execute the following command for building the standard sessions of Isabelle/DOF:

foo@bar:~$ isabelle build -D . -x Isabelle_DOF-Proofs -x HOL-Proofs

This will compile Isabelle/DOF and run the example suite.

Usage

Opening an Example

If you want to work with or extend one of the examples, e.g., you can open it similar to any standard Isabelle theory:

isabelle jedit -d . -l Isabelle_DOF Isabelle_DOF-Example-Scholarly_Paper/IsaDofApplications.thy

This will open an example of a scientific paper using the pre-compiled session Isabelle_DOF, i.e., you will not be able to edit the default ontologies defined in the Isabelle_DOF session. If you want to edit the ontology definition, just open the theory file with the session Functional-Automata:

isabelle jedit -d . -l Functional-Automata Isabelle_DOF-Example-Scholarly_Paper/IsaDofApplications.thy

While this gives you more flexibility, it might "clutter" your editing experience, as a lot of internal theories are loaded into Isabelle's editor.

Releases

For releases, signed archives including a PDF version of the Isabelle/DOF manual are available. The latest release is Isabelle/DOF 1.3.0/Isabelle2021-1:

• Isabelle_DOF-1.3.0_Isabelle2021-1.pdf
• Isabelle_DOF-1.3.0_Isabelle2021-1.tar.xz
• Isabelle_DOF-1.3.0_Isabelle2021-1.tar.xz.asc

Older releases are available here.

Repository Structure

The main branch of this Repository is developed using the latest official release of Isabelle (which is, at point of writing, Isabelle 2022). This is also the main development branch. In addition, he Isabelle_dev branch is used for testing Isabelle/DOF with the latest development version of Isabelle.

This repository is structured into several Isabelle sessions, each of which is stored in a subdirectory:

• Isabelle_DOF: This is the main session, providing the Isabelle/DOF system. Furthermore, this session is currently under consideration for a submission to the AFP.
• Isabelle_DOF-Example-Scholarly_Paper: This session provides an example document written Isabelle/DOF. It only requires the core ontologies provided by the Isabelle_DOF session. Furthermore, this session is currently under consideration for a submission to the AFP.
• Isabelle_DOF-Ontologies: This session provided additional ontologies and document templates.
• Isabelle_DOF-Unit-Tests: This session includes various tests for the Isabelle/DOF system, partly depending on the ontologies provided by the Isabelle_DOF-Ontologies session.
• Isabelle_DOF-Example-Extra: This directory contains additional example documents written using the Isabelle/DOF systems, each of which is defined in an own subdirectory.
• Isabelle_DOF-Proofs: This session provides the Isabelle/DOF systems with proof objects. This is required for the deep ontology embedding.
