Description:

PDF/A-3 is a format that differs from PDF/A-2 in only one regard: it allows embedding of arbitrary file formats (such as XML, CSV, CAD, word-processing documents, spreadsheet documents, and others) into PDF/A conforming documents. Other formats in the PDF/A family are as follows:

  • PDF/A-1: "Part 1: Use of PDF 1.4" (2005-09-28)
  • PDF/A-2: "Part 2: Use of ISO 32000-1" (2011-06-20)
  • PDF/A-4: "Part 4: Use of ISO 32000-2" (2020-11)

Centres should note that Part 1 references an obsolete version of PDF, while parts 2 and 3 reference the fully open PDF 1.7.

For more details, see a Wikipedia overview or consult the standards documents, where available.

VeraPDF is an open-source validator for PDF/A 1-3 formats.
