LaTeX Project LWG
Background
In 2020 the LaTeX Project announced the start of a project to enhance LaTeX to fully and naturally support creation of structured document formats, in particular the “tagged PDF” format as required by accessibility standards such as PDF/UA.
This Liaison Working Group’s purpose is to allow LaTeX Project contributors to interact and collaborate with members of the PDF Association on this project.
Under the terms of LWG operations, the scope of the group is limited to the project defined by the LaTeX Project.
Objective
Assist the LaTeX community in generating best possible accessible STEM documents or other documents with complex technical and mathematical content in PDF format.
Develop general guidelines on how to tag complex technical documents in the best possible manner to achieve accessibility.
Status
As of Q4 2025 key subjects currently under discussion include, but are not limited to:
- Development of the publication “Best practice guide for Math in PDF”
- Development of the publication “Mapping LaTeX semantic model to Tagged PDF semantic model”
- Discussions addressing questions from LaTeX community around Tagged PDF
- Assist other Technical Working Groups of PDF Association in resolving issues related to Math in PDF
Accomplishments
- Final draft of “Best practice guide for Math in PDF”.
