PDF/UA Reference Suite

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. Note that PDF supports the use of additional structure elements that can be present but do not impact the content or logical stream interpretation or representation.

Questions or concerns about these samples from the general public may be directed towards; members should post in the PDF/UA TWG.
