Tagged PDF structure

This repo supports:

  • a luatex command line utility to extract and create representations of Tagged PDF structure element hierarchies as ASCII trees, XML, etc. The XML has an associated RelaxNG schema.

  • an XML stylesheet to transform the XML tree of Tagged PDF structure element hierarchies into simplified PlantUML tree widget (salt) visualization diagrams that can be included in AsciiDoctor and Metanorma documentation.

Environment

These utilities can be used as standalone command line tools in Linux and Mac environments:

# Linux
sudo apt install texlive-binaries

# Mac
brew install mactex    # Warning! this is big (6.9GB) and slow to install!
