Content Authenticity, Liquid Mode and Read Order
Follow us:
This week’s conversation is a lively one with Leonard Rosenthol, Senior Principal Scientist at Adobe. He opens the door to the world of content authenticity and tamper-evident files, then helps demystify the PDF/UA Identifier and why it always shows as unverified. Along the way, there’s a heartfelt call for NVDA and JAWS to join accessibility standards work, and Leonard shares how Liquid Mode in Adobe Acrobat Mobile has been quietly bridging gaps for screen reader users like those on Apple VoiceOver.
