![]() ![]() * – PDF/UA conforming PDF files may be readily exported to highly structured, consistent HTML, ideally suited for restyling.WINDOWS AT SUPPORT (JAWS, NVDA, ZOOMTEXT, ETC) INHERENTLY PLASTIC: READILY RESTYLE TEXT SIZE, COLOR, FONT, ETCĬURRENT SOFTWARE CAN READILY RESTYLE TEXTĪ RELIABLE PORTABLE FORMAT THAT BASICALLY STATICĮNCOURAGES DISTINGUISHING STYLE FROM STRUCTURE The idea in this article is to inform on the appropriateness of each format by comparing their relative strengths for assistive technology purposes in a variety of relevant use-cases. PDF/UA, the new International Standard for Accessible PDF to be published in Q3, 2012 will provide explicit rules allowing developers to produce software to ensure PDF files are accessible. Even most tagged PDF is still poorly tagged. The specification for PDF, no longer owned by Adobe Systems and now known as ISO 32000 has included accessibility features since 2000 but not much guidance for developers.Ĭonsequently, the vast majority of PDF files are still untagged. Technically, PDF is vastly more complex than HTML, and entirely distinct from OOXML. Historically, PDF has not enjoyed such friendly relations with the AT user or developer community. Correspondingly, OOXML is generally considered accessible, even if current implementations (both Microsoft’s Word and the free Open Office) suffer a few limitations. It’s been a longtime goal for both Microsoft and Assistive Technology developers to find ways for OOXML (the format used by current versions of MS Word) to play well with AT, and generally, it does. At least within the page content itself, text and graphics are generally in more-or-less the right order. If the website’s manager has done a good job, the site as a whole is readily “consumable” by the technologies that check, display, feed or otherwise deliver for “end-users” with various needs, both human or machine.Īny piece of software worthy of the name “assistive technology” can read vanilla HTML. Simply remove any CSS and inline styling and you’ve got plain text and markup. What is usually meant is that HTML is inherently accessible, and in a strictly limited sense, that’s pretty much the case. It’s generally considered that “HTML is accessible”. Much is left unsaid! I know that, but this is an article, not a book, ok? Feel free to leave a comment. The purpose is limited to identifying some inherent features and capabilities that each brings to addressing the needs of assistive technology users. ![]() This article compares several popular electronic document file formats.
