Why it Matters

The PDF-UA ID is a piece of metadata contained within the document properties. The identifier tells users that the document claims technical compliance with PDF-UA standards.

Rule Description

The Algorithm (in simple terms)

The PDF-UA ID must be added in order to be PDF/UA compliant.
