What are the fundamental accessibility techniques for PDF, and how should a document’s components, such as title, table row header, table spanning more than one page, nested list, caption or formula, be tagged for accessibility? When searching for clear-cut answers to everyday tagging situations, however, practitioners often find locating the right content to be cumbersome, sometimes ambiguous, or simply inconclusive.

Taking this situation as a starting point, the PDF Accessibility Liaison Working Group (LWG) is working towards the development of a full set of techniques to demonstrate correct solutions for all tagging issues, and is presently finalizing its initial release.

The TWG was originally formed to continue the work started at the December 2018 PDF Techniques Accessibility Summit in Edinburgh; the development of industry-supported example PDF files demonstrating WCAG-style Techniques for achieving accessible PDF files that conform to both PDF/UA and WCAG.

Today, the PDF Accessibility LWG meets weekly to review examples of “pass" and "fail" Techniques for PDF, together with appropriate metadata. The initial release is not yet scheduled but the working group intends to begin publication in 2023.

Participation in this LWG is open to all PDF Association members and by invitation, to non-member accessibility professionals and end-user subject matter experts.

Under the slogan “Friends in France” we are very happy that we will have 2 in person meetings during the PDF Week in Paris with the aim to finalize the publication of the PDF/UA Fundamentals as well as preparing the next Use Case packages:

  • May 3rd: 09:00 to 10:45 CET
  • May 4th: 11:00 to 17:30 CET

As usual for Working Group meetings, these meetings will also be held online.

Participation in these meetings is open to all members online, and all PDF Week Paris 2023 attendees on the premises. If you will join us in-person, please indicate your scheduled attendance by registering for PDF Week 2023 Paris before April 17, 2023.
