DOC Comparison of Open Source Documentation Systems: ReStructuredText and Diátaxis

Diátaxis is a framework that organizes documentation into four clear categories: Tutorials, How-to Guides, Explanations, and References. It may help us to make our documentation more structured and user-friendly, allowing everyone to quickly find exactly the information they need—whether they’re beginners or experienced developers.

This clear organization enhances the accessibility and quality of our documentation. As well as providing a guide to documentation content, Diátaxis is also a guide to documentation process and execution. Diátaxis is a way of thinking about and doing documentation. It is a systematic approach to technical documentation authoring.

ReStructuredText (reST) and Diátaxis are both documentation systems but serve different purposes and have different areas of application. Below is a comparison of the two systems:


1. Purpose and Application

  • ReStructuredText (reST)

    • A markup language primarily used for technical documentation. It is part of the Python Docutils project and is commonly used for creating documentation for Python projects.

    • ReStructuredText serves as an input format that can be converted into various output formats such as HTML, LaTeX, PDF, etc.

  • Diátaxis

    • A framework for structuring documentation that is based on classifying content into four main categories: Tutorials, How-to Guides, Explanations, and References.

    • Diátaxis is more of a methodology or model for organizing content rather than a specific markup language or format.

2. Syntax and Format

  • ReStructuredText (reST)

    • Uses a simple, text-based markup syntax, similar to Markdown, but more powerful. It allows the creation of complex documents with relatively simple syntax.

    • It supports various formatting elements like headings, lists, code blocks, tables, and links.

  • Diátaxis

    • Does not have its own syntax, as it is a framework for organizing documentation. The structure of Diátaxis can be implemented in various formats, including reST, Markdown, or HTML.

    • The methodology emphasizes how content should be organized and presented rather than focusing on a specific format.

3. Documentation Structure

  • ReStructuredText (reST)

    • Provides a hierarchical structure through paragraphs, sections, and subsections.

    • It is flexible enough to adapt the organization of documentation to the project's needs but does not offer specific guidance on structuring content.

  • Diátaxis

    • Organizes content into four well-defined areas:

      • Tutorials: Step-by-step instructions for beginners.

      • How-to Guides: Instructions for specific tasks.

      • Explanations: Background information and concepts.

      • References: Comprehensive and precise technical details.

    • The goal is to make it easier for users to find and understand information by structuring it logically.

4. Flexibility and Adaptability

  • ReStructuredText (reST)

    • Highly flexible and extensible through extensions and directives. It allows customization of the appearance and structure of documentation.

    • However, it can become more complex as documentation requirements grow.

  • Diátaxis

    • Provides clear guidance for structuring documentation, which is particularly useful for large projects.

    • The methodology itself is flexible and can be integrated into various formats but requires a specific structure that may not be suitable for all types of projects.

5. Integration and Use

  • ReStructuredText (reST)

    • Widely used in the Python community and integrated into many Python documentation tools like Sphinx.

    • Can easily be integrated into build systems to automate the creation of documentation.

  • Diátaxis

    • Not limited to a specific tool but rather a conceptual approach that can be applied in various tools and formats.

    • The methodology is often used in conjunction with existing documentation systems like reST or Markdown.

6. Target Audience

  • ReStructuredText (reST)

    • Developers and technical writers who create technical documentation, especially in the Python world.

  • Diátaxis

    • Technical writers, information architects, and developers who want to structure their documentation clearly and user-friendly.

Conclusion

  • ReStructuredText is ideal if you need a powerful and flexible markup language that can be used in many documentation tools.

  • Diátaxis is useful if you are looking for a structured method to organize your documentation into logical and user-friendly sections.
