We’ve done PDF Day events and technical conferences across Europe, in the US, in Australia, and elsewhere. This Electronic Document Conference is the first PDF Association event that’s open to all technologies pertaining to documents. It’s about explor …Happy new logo!
2006: The PDF/A Competence Center A new year brings new things, and 2019 is no exception! The “four red blocks” logo was first created for the PDF/A Competence Center in 2006. When that organization became the PDF Association in 2011, the design was ad …Save-The-Date: PDF Day France, Toulouse, April 4, 2019
PDF Day France will be the first French-speaking event of the PDF Association, organised by our member ORPALIS. It will take place in Toulouse which is the home ground of Airbus and we are very happy that Airbus will present a case study around its usage of PDF in their document management environment!Electronic Document Conference: Call for Papers
Prospective presenters at the Electronic Document Conference 2019 are invited to submit high-quality original proposals for 25-minute presentations on subjects of interest to developers and technical product managers concerned with electronic document implementations.Have we passed ‘peak PDF’?
How do we gain insight into how users’ views of documents are shifting? Google Trends is an increasingly interesting source of high-level marketplace data. By aggregating Google’s search data over time, reporting a term’s popularity as compared with all other searches.
The year 2011 is going to be an interesting one. Not only will PDF/A see the addition of a second part PDF/A-2 to catch up with technological developments; some related standards will also enter the stage.
A new standard called PDF/UA will address accessibility of PDF documents. It has been worked on for about five years already and is going to be finalised and published in 2011.
The world of metadata for file formats like PDF will see a very important step as well: Adobe is currently releasing their XMP (Extensible Metadata Platform) specification to ISO, and if all goes well, XMP will be an official ISO standard in 2011.
The PDF/A committee in ISO always saw the need to not only cover archival in the sense of visual reproducibility, but to also capture and preserve as much semantics and content structure as possible. In order to achieve this, the conformance level A was introduced (although some say the letter A stands for advanced, linking the A to accessible may be more adequate). Level A requires that text can be mapped to Unicode and that the semantic structure of the content for example its reading order must be reflected in the tags used to structure the PDF. One of the aspects the PDF/A committee was not able (and actually never attempted) to achieve was to offer strict rules or even guidance on how to ensure or enforce good quality tagging. There are also no provisions in PDF/A on how to best take advantage of structure information inside a tagged PDF.
This is exactly what PDF/UA is taking care of. The preparation of the PDF/UA standard has taken quite some time for a reason it was very important to the PDF/UA committee to get it right as much as possible the first time around. Not only should the use of the PDF/UA lead to better structured PDF, but it should still remain feasible and cost efficient to get there, whether for those producing tagged PDF content, for software vendors developing tools for creation of well structured PDF, or for makers of assistive technology.
The two accessibility presentations in this track will bring you up to speed regarding accessibility in PDF, as well as PDF/A, and beyond. Both speakers David Hook, Director Product Management at Crawford Technologies and Duff Johnson, CEO, Appligent Document Solutions have been involved in accessibility for a very long time, and both have actively contributed to the development of PDF/UA.
During the past decade several PDF related standards began to make use of XMP metadata instead of using the simpler and less powerful Document Information mechanism, which essentially is a list of key value pairs in PDF syntax. Even PDF itself is moving towards using XMP exclusively for any general purpose metadata. The next version of PDF, to be called PDF 2.0 and to be published as ISO 32000-2 in late 2011 or in 2012, will deprecate the use of the Document Information mechanism.
While some communities like photographers make very active use of XMP for embedding information like copyright notices, keywords or descriptions, metadata in the form of XMP inside PDF files has not yet become as prominent and widely used in the world of document management and archiving. A number of companies who switched from other ways of associating metadata with their documents though found substantial advantages in using XMP. In todays world, where exchange of structured data using XML-based formats is more widely understood than ten years ago, XMP turns out to be a natural fit for most metadata needs. The metadata sessions track will get organisations started looking into the use of metadata inside PDF and PDF/A, and will illustrate the power and cost efficiency of XMP over other approaches.
