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.
Over the next few weeks we would like to introduce our speakers on the Technical Conference Europe 2013, their presentation’s topics and their personal view on the world of PDF and related ISO standards. So we prepared some little interviews with the speakers for the conference.
Francois Fernandès studied computer science and economics at the Reutlingen University. Then he started as a developer and consultant at levigo solutions GmbH where he had his first contact with PDF in 2005 some months before the first PDF/A release.
Instead of using the typical Hello World program, he learned the Java programming language by implementing a PDF parser.
The ISO committee around the PDF standards is about to search for a formal representation of the allowed elements within PDF documents. And there is a huge number of legal elements. Were talking about all possible dictionaries with numerous kinds of values within. All those dictionaries and their contents are described in the standards (ISO 32000-1, ISO 19005-1, etc.) but there is no technical (or formal) representation of these definitions.
This is what Adobes DVA and our PDF Formal Syntax is all about: Describing all possible types in both a machine and human consumable language. Hopefully, one day, there will be such a language including some default sets that formally describe what a PDF-1.7, PDF-2.0 or PDF/A-1 may contain. If there are such sets and a well-defined formal language, there will be many possibilities to profit: Generating code for loading and/or writing, validating PDFs, or even generating customizable documentation like this dictionary is represented as the C++-Class XYZ. Building and visualizing differences between PDF-versions can be automated, allowing an easy overview of what has technically changed between two versions of the PDF standard.
I will definitely attend Introduction to PDF 2.0? as Im curious to see what the next big version step in PDF will be and Colour Management for PDF developers as colour management has always been a major pain for my PDF development work.
My personal history with PDF started in 2005, some months before the official release of ISO 19005-1 (PDF/A-1). I started working for levigo solutions GmbH and my task was to write PDF document viewing logic in pure Java. The only problem: I didnt have any knowledge about Java, nor about the PDF standard itself besides using PDFs. So my first Java program wasnt the typical Hello World! program, instead it was a PDF lexer/parser. And I still keep the very first screenshot of my first successfully parsed PDF document.
As I have been working in the area of long term preservation, Id love to see further adoption of PDF/A. PDF/A is the only real option for having future-proof documents that are safe and worth archiving. The adoption is already pretty good, which is also a result of the PDF Associations good work, but it could still be improved.
