Save the Date: PDF Days Europe 2018, May 14-16, in Berlin

PDF Days Europe is the most popular PDF event of the year. It’s where the PDF industry meets, and where institutional and corporate users come to learn what else PDF could do for them. The first two PDF Days will offer a broad range of educational sessions focussed on current and perennial topics in the world of PDF technology implementation.

The Power of the Page

It’s a question that vexes vendors of web-based solutions everywhere: why do people still insist on PDF files? And why does PDF’s mindshare keep going up? “PDF is such antediluvian technology!” they say. “It’s pre-web, are you kidding me? It’s so old-f …

PDF Association technical resources: an overview

PDF is PDF because files produced with one vendor’s software can be read using a different vendor’s software with no loss of fidelity. Interoperability is key to our industry. The PDF Association is a international membership organization dedicated to …

2022: The last year of paper for records-keeping

NARA (The National Archives and Records Administration) is the final depository for the long-term records generated by all other agencies of the U.S. Federal Government. The agency has a key role in preserving the cultural history of the republic as we …

Both symbol and substance of interoperability


PDF gearsThere’s a good reason why Wikipedia’s entry on “de facto standard” specifically references the portable document format, or PDF.

A truly standards-based, open technology, PDF’s value is based on a premise of interoperability; the ability to easily exchange documents reliably across town, between operating systems and over decades.

For these purposes, PDF has no real competition; indeed, Google Trends clearly shows, users keep asking for more PDF.

Mere publication of a file format specification doesn’t make a de facto standard, however. It takes a community.

Software developers working with electronic documents can only realize PDF’s value proposition for their customers when they make interoperability with other vendors’ PDF creation or processing software a primary consideration.

PDF works because vendor X knows how to make a file that vendor Y will know how to read. Both vendors are motivated to understand the specification; to refrain from making mistakes in file creation, or in damaging the files their software encounters, and so on.

At 21 years of age, PDF may be pretty old for an internet-era technology, but it keeps finding new uses. Combine PDF’s power-features with the fact that it’s a mature ISO standard, and a de facto standard for billions of end users worldwide, and PDF looks more like a sleeping giant.

The power of interoperable PDF

The possibilities are endless. Complete SDKs are available to create, edit or display files using any feature of PDF, including, but not limited to:

  • For electronic documents, seamless, digital-signature based tamper-proofing, authentication, certification, revocation and access
  • Complete accessibility of the content in PDF documents to users with disabilities
  • Integration of geospatial data with correctly-scaled PDF pages
  • Automated transaction processing with ZUGFeRD or similar e-invoicing models
  • PDF/A, the future-proof electronic document archival subset of PDF
  • XML metadata that’s part of the file, not just retained in an indexing system
  • Support for multiple languages and pronunciations
  • Support for fully standardized rich commenting and highlighting
  • Support for other annotations (shapes, redaction, rich text, movies and more)
  • Fillable forms operated by ISO standardized JavaScript for PDF
  • 3D data representation via PRC for PDF
  • Joining world-wide consensus on PDF/A, the future-proof electronic document archival subset of PDF

PDF breeds cooperation

Both at the ISO and industry association levels, the PDF industry is characterized by regular technical meetings to discuss, plan and write the next version of PDF. Everyone wants to share their experiences to ensure clear text and reduce barriers to interoperability.

That’s why there are over 150 paying members of the PDF Association, with many joining twice-a-year ISO meetings to help iron out consensus on where PDF should be going.
