veraPDF Validation

The veraPDF validation engine implements the PDF/A specification using formalizations of each “shall” statement (i.e., each requirement) in PDF/A-1, PDF/A-2 and PDF/A-3. These rules are implemented as XML documents known as Validation Profiles and are applied by veraPDF software at runtime.
