PDF/UA-1 rule 7.2-33: Natural language for document metadata cannot be determined

May be fixed when the cause is a missing document language lang, metadata

What veraPDF reports

Natural language for document metadata cannot be determined

veraPDF rule 7.2-33 = ISO 14289-1:2014 clause 7.2, test 33, checked on PDF object XMPLangAlt.

What the requirement says

Natural language for document metadata shall be determined

Can it be fixed automatically?

May be fixed when the cause is a missing document language. The fix sets the document language (/Lang) when the file declares none, which lets the language of this text be determined. Not measured for this rule — the free check shows whether it disappears for your file.

How to fix it by hand

Set the document language (and the language of passages in other languages) in the authoring application before export; the PDF then carries a /Lang entry that screen readers use.
