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
- 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!
