Building on the great work done by the PDF Association supported by the Defence Advanced Research Projects Agency (DARPA), veraPDF has developed an open-source PDF checker based on the Arlington PDF Model. This application is separate from the veraPDF PDF/A and PDF/UA validator but comprises a very familiar package of GUI and command-line applications as well as a Docker-based REST API and online web demo.
The PDF Arlington Model covers the requirements of the PDF object model as specified in ISO 32000-2:2020 (PDF 2.0, including resolved errata) as well as some (but not all!) aspects from earlier Adobe PDF references and various extensions. It is based on its own formal grammar and serialised as a set of TSV files (see also the Arlington Model Notes). References to Tables and clauses below all refer to ISO 32000-2:2020.
veraPDF was originally developed with funding from the PREFORMA project (2014-2017). In 2018, it was a finalist for the Digital Preservation Awards 2018 in the Software Sustainability Institute’s Award for Research and Innovation.
