TechNote 0010, cover image.Berlin, Germany– August 4, 2017 – The PDF Association, a not-for-profit organization designed to foster universal public standards for PDF technology, today announced the publication of Technical Note 0010, a set of 29 exhaustively researched and peer-reviewed resolutions to a variety of ambiguities in the PDF/A specifications.

Technical Note 0010 was produced by the PDF Association’s PDF Validation Technical Working Group (TWG). The TWG developed this content in the context of an in-depth review of existing ISO 19005 (PDF/A) specifications conducted between October, 2014 and December, 2016 for the purpose of developing the open-source veraPDF test suite and veraPDF validation software. Ambiguities in PDF/A were identified by:

  • Formally analyzing the PDF/A specifications in the process of implementing veraPDF
  • Reviewing the performance of existing PDF/A validators
  • Discussing the questions posted to the TWG mailing list
  • Resolving controversial questions via a ballot

Boris Doubrov, PDF Association Board member and the technical lead on development of the veraPDF test suite said, “The veraPDF corpus continues the work of the PDF/A Competence Center’s Isartor Test Suite, but in a more comprehensive manner, and with complete coverage of all three current parts of PDF/A.”

We fully expect to see the veraPDF software, which reflects the findings documented in TechNote 0010, used in most memory institutions handling electronic documents worldwide.”
