Following the success of our previous interop workshops in Cambridge, England and Boston, Massachusetts, the 3rd PDF 2.0 Interop Workshop takes place on May 16, 2018 as part of the post-conference program immediately following this year’s PDF Days Euro …Post-Conference of PDF Days Europe 2018 in Berlin
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.
When around 2002 the committee that created the PDF/A standard decided to rely on XMP (eXtensible Metadata Platform) for the inclusion of metadata in PDF/A files they probably had no clue which developments it would kick off in the years to come. Being a brand new technology invented by Adobe and first presented in 2001, being on open specification, publicly available for anyone to use very few fully understood the implications.
When developers especially those who work together in the Technical Working Group of the PDF/A Competence Center realized the impact of these metadata in PDF/A provisions, not all of them had a smile on their face. At first glance these provisions appeared to be overly strict and unnecessarily convoluted. Metadata has rarely been fun to deal with, but now for many it seemed to turn from inconvenient to painful.
But dont be fooled! By now the support for XMP metadata has been implemented in numerous applications, and in many instances offers very elegant ways to review or enter XMP metadata. Quite frequently a user wouldnt even realize that metadata are stored in XMP format it just works. And software vendors as well developed a much better understanding of how to best deal with metadata both in the form of XMP as well as in the context of other previously introduced formats like IPTC or EXIF.
Admittedly the matter of metadata is slightly more demanding in PDF/A and for a good reason: The PDF/A standard manages to make the metadata side of PDF based archiving as reliable as the content side. While this comes at a price, it does not pose unsurmountable problems. Some familiarity with the principles of metadata in general and those of XMP in particular will be a prerequisite though.
The same way everyone in the software industry by now had to learn Unicode when dealing with text intelligently, everyone now has to become fluent with metadata in the form of XMP, at least when dealing with PDF, and specifically PDF/A for archiving. And for the same reason we do not want to go back before Unicode, we will not want to go back before XMP too much valuable information would be lost, and too much ambiguity would persist.
Of course there is no rose without a thorn. Organisations who have embarked on the journey to XMP metadata in PDF/A land have had to learn a lesson or two, though I dare say it has always been worth the effort. At least thats the conclusion both Jan-Michael Rehn from Bosch and Klaus Baumeister from the European Patent Office come to, when they explain their respective projects of using XMP metadata in PDF/A files.
Those who always thought there is no fun ever to be had with metadata may want to revisit their position after taking in the thoughts of Frank Biederich from Adobe, who provides the introduction to the metadata track.
Guidance towards XMP Metadata in PDF/A on a more technical level is offered by Thomas Merz from PDFlib, who has been successful many times at previous occasions to make it easy for non-geeks to understand the essentials of the XMP format and its use in PDF/A.
