veraPDF consortium releases 0.4 of its prototype PDF/A validator

As CEO, Duff coordinates industry activities and promotes the advancement and adoption of PDF technology worldwide.
The veraPDF consortium has released an update to its prototype veraPDF validation library. This 0.4 release delivers:
- a working validation model and validator;
- an initial, unverified PDF/A-1b validation profile; and
- prototype PDF feature reporting (characterisation).
This release, which is ahead of schedule, enables users to test the first implementation of PDF/A-1b validation on single files via a graphical user interface (GUI).
The latest version of the 0.4 release can be obtained from: https://software.verapdf.org/releases
Release notes for version 0.4 are available on GitHub, as are instructions for unpacking the zip archive, running the GUI and loading the PDF/A-1b profile.
The PDF/A-1b profile has been tested internally against our corpora, but has not been fully assessed by the PDF Association's PDF Validation Technical Working Group (TWG), nor has it passed the PREFORMA project's acceptance tests.
