The PDF Accessibility Liaison Working Group (LWG) was originally formed to continue the work started at the December 2018 PDF Techniques Accessibility Summit; producing industry-supported example PDF files demonstrating techniques for achieving accessible PDF.
Today the PDF Accessibility LWG meets every two weeks to review example "pass" and "fail" PDF files and develop appropriate metadata.
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. Please email the PDF Association to learn more about becoming an invited expert.
NOTE: Invited experts in this LWG do not enjoy any other rights of membership in the PDF Association, nor do they have access to PDF Association members-only resources, including the PDF/UA TWG and PDF/UA MWG or to draft ISO documents.
