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

With only a month left until the doors open for PDF Accessibility Days in Copenhagen on November 12-13, 2015 , I got in touch with Duff Johnson, who will be speaking at the conference about “How PDF/UA relates to WCAG 2.0”. As I have always struggled to see the relevance of WCAG 2 in my daily life when it comes to getting a job done as a PDF software developer and document producer alike, I grabbed the opportunity and asked Duff for an interview
Interviewer: Olaf Drümmer
OD. You are going to talk about “How PDF/UA relates to WCAG 2.0”. Why would anybody care? Isn’t the W in WCAG about web pages or web sites, whereas PDF/UA is about accessible documents represented in the PDF file format?
DJ. Thats a good question, and there are many valid ways to answer it. There are two things Id like to stress.
PDF is, in fact, how to do a fixed-layout document in the web context.
Second, we have to talk about PDF in the WCAG 2.0 context because WCAG 2.0 is claimed to be technology-neutral, and thus applicable to PDF. Many who are adopting WCAG 2.0 are doing so under the presumption that they will be able to apply WCAG 2.0 equally across all their electronic content; not just web pages, but PDF documents, Excel spreadsheets and everything else. Their desire for a one-size-fits-all solution is understandable – and achievable – but technically, WCAG 2.0 is only part of the answer.
OD. If I am not mistaken, WCAG has never managed to establish a widely shared understanding exactly what accessible PDFs should look like – are you seeing this changing with the advent of PDF/UA? Will all PDFs be accessible in the foreseeable future?
Very commonly, when I receive a tagged PDF file, I open it with a tool that converts the tagged content to HTML. This allows me to quickly review the file as it is presented (in the best case) by assistive technology.
Im afraid what I usually find is that although the content within a given page may be ok, the document as a whole is very poorly tagged. This is usually as much caused by a problem with the document authors understanding of how to create an accessible document as it is with the technology they are using.
That said, these days I can open a bank-statement from any of several huge US banks, and find a very well-tagged PDF. That certainly wasnt true before PDF/UA!
To return to your question the advent of PDF/UA has certainly speeded development of software that creates PDF documents that conform to PDF/UA, and thus, to WCAG 2.0.
The proportion of tagged to untagged PDF will increase slowly over time. I dont think it will ever hit 100%, but theres tremendous potential to make tagged PDF the norm rather than a matter of 1 in 7.
OD. Is the W3C working group in charge of WCAG welcoming the publication of the PDF/UA standard? Are they pointing to at as a more focused guideline for creating accessible PDFs? Will PDF/UA incorporated into a next version of WCAG?
The Web Accessibility Initiative (WAI), the W3C working group which owns WCAG 2.0, refers to PDF/UA in its PDF Techniques as “of note. This language hasnt changed since 2012, when WAI published its first PDF Techniques.
Its unclear to me how WAI wishes to address PDF. WCAG 2.0 isnt really configured to work with 3rd party specifications beyond specific web technologies. The WCAG2ICT document, as presently drafted, adds little light with respect to PDF accessibility. I continue to think the best way to proceed is likely via a comprehensive overhaul of existing PDF Techniques to include proper reference to PDF/UA.
OD. According to WCAG content can only be considered accessible if two or more solutions – reading tools or assistive technology – exist in the market that actually provide access to that content. I have been concerned that this tends to slow down development of new tools and concepts. Is this any different with PDF/UA? How does PDF/UA encourage development of new ways of creating and using accessible documents?
WCAGs concept of accessibility supported is very reasonable in principle, but I agree with you that it inhibits development. As WCAG’s authors themselves will tell you, WCAG 2.0 is not animated by interoperability.
OD. What are the one or two most common and counter productive misconceptions about accessible PDF?
The most common misconception: that creating accessible PDF is somehow mysterious. Not in the slightest. If you can create an accessible Word file or HTML page you can create an accessible PDF file.
The most counter-productive misconception: the idea that WCAG 2.0 by itself can suffice to describe accessibility requirements for PDF documents, software applications, kiosk devices, and so on. The results are clear; incomplete, imprecise specifications mean increased uncertainty and therefore risk, so developers place their efforts elsewhere. For the rest of us: slow progress towards generally accessible content, as WebAIMs surveys attest.
OD. When did you create your first accessible PDF? What has changed since then?
I started playing with tagged PDF in 2000, when Adobe contacted me to explain what they had in mind, and to show me some pre-release software that included the capability to create and manage tags. When Acrobat 5.0 shipped in 2001 my company at the time was ready with PDF Tagging Services.
Im very happy to see that a healthy industry has grown up since the day when Adobe was the only software vendor and I was the only service provider doing accessible PDF. Today there are dozens of different software applications at many different levels that deal with tagged PDF, and hundreds of providers who provide tagging as a service, either via the source file (such as InDesign), or as a remediation of an existing document.
OD. If you had one wish regarding accessible PDF – what would that wish be?
That those writing regulations covering the technical aspects of accessibility would utilize the relevant technology-specific standard – in PDFs case, PDF/UA – in addition to WCAG 2.0.
