On Wednesday, May 16, 2018, directly following PDF Days Europe, the PDF Days Post-Conference offers a variety of workshops on PDF 2.0 Interop or PDF/UA.PDF Days Europe 2018 – schedule of sessions
Fittingly for the tenth anniversary of PDF’ becoming an ISO standard, standardization will play a significant role this year. The focus will be on recent developments, with an eye on the future. The agenda also includes PDF market analyses, next-generation PDF for mobile devices, universally accessible PDF files and the industry-supported veraPDF validator initiative.Hotel Recommendations and Sightseeing Tips for PDF Days Europe 2018 in Berlin
You will visit the No. 1 PDF event – the PDF Days Europe 2018 in Berlin? Great! Here are some hotel recommendations and sightseeing tips near the event location (SI Hotel).A double anniversary for PDF Days Europe 2018
Richard Cohn, Principal Scientist at Adobe, one of the two co-authors of the original PDF specification in the era of Acrobat 1.0 gives the keynote on 25 years of PDF during the PDF Europe 2018.PDFcontainer – a proposal
Introduction PDF technology profiles can be leveraged to provide trusted, predictable containers for record types that often present workflow and preservation challenges, with email and case files (associated files in arbitrary formats) as primary use- …
As we noted the Sophos blog has a long piece about modern-day link-farming with PDF documents. Less scrupulous marketers have discovered that Google trusts PDF documents more than HTML pages; they’ve been “poisoning Google search results” accordingly.
The notion that PDF document authors are innately pure of heart as compared to HTML pages is doubtless being re-evaluated right now, especially since PDF files are an enormous proportion of important web content, and interest in PDF continues to grow.
Apart from tweaking search algorithms so that PDF files aren’t receiving undue credit just because they are PDF files, what should Google (or other search engine developers) do about PDF? What are, for example, the benefits awaiting search-engine and other application developers that leverage high-quality PDF files?
Once the PDF specification is fully supported (it’s an ISO standard; it won’t bite!) lots of things get both easier and better.
An idea for Google and other search engine developers: to really impress people with your acumen in handling PDF documents, go beyond simply treating PDF as a page-description model, and support high-quality tagged PDF!
What might be possible if search engines were savvy to PDF’s model for semantics and logical reading order?
Although PDF is a page description format it can include all the necessary instructions to allow consuming software to make other choices. Supporting tagged PDF (ISO 32000-1:2008, 14.8, download it for free), by itself, would generate other fairly dramatic new features for browsers.
Accurate abstraction of tagged PDF’s content to vanilla HTML, much as callas’s pdfGoHTML does today (sadly, it requires Adobe Acrobat), would facilitate total flexibility in using tagged PDF on mobile devices. Apple’s iOS browser, Safari, effectively does this today on some HTML pages with “Reader View” – why not also for PDF?
Besides improved indexing for search and the ability to reliably reuse PDF content in web browsers there are many ways in which complete support for PDF technology would deliver substantial value to content management systems and end users alike:
It’s all ISO-standardized, and thus, inherently interoperable.
PDF is here to stay, and tagged PDF offers tremendous advantages for both search and re-use applications. It’s high time that search engine, browser and other application developers decided to think again about the crusty old format users have loved for over 20 years.
