PDF/UA Reference Suite

Screen-shot of 10 PDF file icons.To serve as a reference for software developers and practitioners interested in best-practices for creating tagged and accessible PDF files, the PDF Association’s PDF/UA Competence Center has posted a set of 10 PDF documents conforming to PDF/UA-1.

Ranging from publications to transactional records, the collection represents a cross-section of documents reflecting the wide variety of uses for PDF technology.

The set includes the latest 1.02 release of the Matterhorn Protocol, the PDF Association’s  definitive algorithm for PDF/UA conformance.

The PDF/UA Reference collection demonstrates correct tagging in a number of sophisticated cases, including:

  • Content spanning multiple pages
  • Complex table structures
  • Multiple languages within a single document
  • Interactive forms and JavaScript
  • Links targeting structure elements

While each file in the collection complies with PDF/UA-1 many also comply with PDF/A-2, the archival standard for PDF.

The PDF/UA Competence Center wishes to thank the PDF Association member companies contributing sample PDF files to the set. In alphabetical order, they are:

The members of the PDF/UA Competence Center hope this information is useful to those seeking to improve their understanding of tagged PDF!

NOTE: Questions or concerns about these samples may be directed to Duff Johnson, current chair of the PDF/UA Competence Center.
