My university is pushing for us to ensure that all our documents are accessibility-friendly. I write all my documents in LaTeX and have been taking the steps and measures to ensure that everything I generate is tagged, has alt text, and colour-blind-friendly.

Unfortunately, it seems the only way I can check for PDF-UA compatibility is with Acrobat Pro which the uni does not provide for us. What’s more is that I use Linux and Acrobat doesn’t work in that OS.

Is there a Linux-friendly libre software that can check if my PDF document is compatible with the machine-checkable requirements of Matterhorn Protocol?
