Question: Validation for PDF/A-1 without conformance-level #1411

Closed Lolf1010 closed 7 months ago

Lolf1010 commented 7 months ago

Hey, as far as i unterstand it - please correct me if i am wrong - there is a difference between A-1 and A-1a / A-1b. The conformance-levels add additional rules. Based on the enum PDFAFlavour it appears to me that veraPDF can validate A-1a and A-1b, but not "pure" A-1. Where are planning to use veraPDF as a library in our software.

Question Is it possible to validate just A-1? Is is maybe possible to only read and use the ValidationProfile for A-1? Is it maybe possible to identify that a PDF is A-1 but not A-1b (for example) by usinggetFailedChecks?

Thank you.

No, PDF/A-1 does not exist without conformance Level (A or B). Note that Level A is a superset of Level B requirements.

In your internal workflow you can specify PDF/A-1 as a synonym of either PDF/A-1a or PDF/A-1b depending on your policies. But on the level of the ISO specification 19005-1 there are only conformance levels: PDF/A-1a and PDF/A-1b.
