The PDF Techniques Accessibility Summit will identify best-practices in tagging various cases in PDF documents. Questions to be addressed will likely include: the legal ways to tag a nested list, the correct way to caption multiple images, the appropriate way to organize content within headings.Refried PDF
My hospital emailed me a medical records release form as a PDF. They told me to print it, fill it, sign it, scan it and return it to the medical records department, in that order. In 2018? To get the form via email (i.e., electronically), yet be asked to print it? Did the last 20 years just… not mean anything! So I thought I’d be clever. I’d fill it first, THEN print it. Or better yet, never print it, but sign it anyhow, and return it along with a note making the case for improving their workflow. The story continues…Slides and video recordings of PDF Days Europe 2018

PDF/UA, like PDF itself, is internally complex, but used correctly, actually makes things easier.PDF Association expands its board of directors
Catherine Andersz of PDFTron Systems, Alaine Behler of iText Software and Peter Wyatt, ISO Project Leader for ISO 32000 enrich the newly elected board of the PDF Association.
PDF was originally intended to serve as electronic paper; a properly rendered page irrespective of software or operating system. Pages, however, aren’t just for reading. Since people like to add notes, draw lines and fill forms, Adobe Systems, the inventors of PDF, decided to cater to these uses as well. PDF rapidly accumulated new features beyond faithfulness to the rendered page it began to mirror the interactive capabilities of real paper.
The first generation of interactive PDF features consisted of annotations of various types. Some allowed users to add text, others allowed users to draw lines and boxes onto the page. Still others go beyond the paradigm of the page, making it possible to add hyperlinks, audio and movies to PDF.
The second generation of interactive PDF brought the ability to deploy a PDFs content outside the page-based world.
Tagged PDF provides the means to effectively deploy a final-form document to a mobile device. Its the same means by which PDF files may be made accessible to users who requires Assistive Technology (AT) to read.
One of the primary motivations for tagged PDF was to achieve compliance with regulations that require electronic documents to be accessible to users with disabilities, but implementers can leverage tagged PDF to accomplish or enhance a wide range of end user activities.
The following table indicates the utlity of untagged vs. tagged PDF content.
|Untagged Content||Tagged Content|
|No semantic types or ordering; content is ordered solely for rendering purposes||Semantic type and order is determined, content may be reused accordingly|
|Search engines cannot reliably access words and phrases||Search engines get reliable access to content.|
|No reliable means of reflowing page content onto smaller devices||Includes information necessary for reflow|
|Real content and artifacts arent distinguished||Consuming software can choose to utilize or ignore artifacts|
|Content copying and extraction is unreliable||Content may be extracted with confidence|
|Not eligible for PDF/A conformance level A||May conform with PDF/A conformance level A|
|Cannot comply with WCAG 2.0 or Section 508||May comply with WCAG 2.0, Section 508 and other accessibility regulations|
|Inaccessible to disabled users||Accessible to those with PDF-aware Assistive Technology|
