Swagger Plugin for DITA-OT

This is a DITA-OT Plug-in used to auto-create valid DITA-based REST API documentation. The documentation can be generated directly from a Swagger file and processed as if it had been written in DITA.

Background

Swagger is an open-source software framework backed by a large ecosystem of tools that helps developers design, build, document, and consume RESTful Web services. While most users identify Swagger by the Swagger UI tool, the Swagger toolset includes support for automated documentation, code generation, and test-case generation.

Swagger2Markup converts a Swagger JSON or YAML file into one or more AsciiDoc or GitHub Flavored Markdown documents which can be combined with hand-written documentation. The Swagger source file can be located locally or remotely via HTTP. Swagger2Markup supports the Swagger 1.2 and 2.0 specification. Internally it uses the official swagger-parser and my markup-document-builder.

This plugin processes the Swagger file to Pandoc markdown, and the converts the markdown to DITA using the Pandoc DITA-OT Plugin

    2. Extract the contents of the package to the directory where you want to install DITA-OT.
    3. Optional: Add the absolute path for the bin directory to the PATH system variable.

    This defines the necessary environment variable to run the dita command from the command line.

Usage

For DITA processing, a swagger file can be defined in either json or yaml format. To mark a file to be passed through for Swagger processing, label it with format="swagger" within the *.ditamap as shown:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE bookmap PUBLIC "-//OASIS//DTD DITA BookMap//EN" "bookmap.dtd">
<bookmap>
    ...etc
    <appendices toc="yes" print="yes">
      <topicmeta>
        <navtitle>Appendices</navtitle>
      </topicmeta>
      <appendix format="swagger" href="Swagger_Definition.json"/>
   </appendices>
</bookmap>

The additional file will be converted to a *.dita file and will be added to the build job without further processing. Unless overriden, the navtitle of the included topic will be the same as root name of the file. Any underscores in the filename will be replaced by spaces in title.
