The PDF Techniques Accessibility Summit’s objective is to establish a broad-based understanding of how PDF files should be tagged for accessibilty. It’s an opportunity to focus on establishing a common set of examples of accessible PDF content, and identify best-practice when tagging difficult cases.Modernizing PDF Techniques for Accessibility
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.
After the first part of PDF/A was published, two more parts arrived. These are not replacements for part 1, however; rather, they offer additional options for archiving PDF documents. All existing PDF/A files remain fully valid.
PDF/A-2 was published in 2011 as ISO 19005-2. Based on PDF version 1.7, which has since been standardised as ISO 32000-1, it makes use of this versions new features. This means PDF/A-2 allows JPEG2000 compression, transparent elements and PDF layers. PDF/A-2 also allows you to embed OpenType fonts and supports PAdES (PDF Advanced Electronic Signatures)-compliant digital signatures. One particularly important innovation is the container function: PDF/A files can be embedded within a PDF/A-2 document.
PDF/A-3 has been available since October 2012. A PDF/A-3 document allows you to embed any file format desired not just PDF/A documents. For example, a PDF/A-3 file can contain the original file from which it was generated. The PDF/A standard does not regulate the suitability of these embedded files for archiving.
The different conformance levels reflect the quality of the archived document and depend on the input material and the documents purpose.
Nomenclature: PDF/A versions and levels are simply given one after another. A PDF/A-1b file, for example, is a PDF file for long-term archiving, of the first generation, with visually reproducible content.
