command line extension proposal

[archive-uk]

Default situation:

VeraPDF allows you to specify the path to a user-defined profile via the "-p" command line switch. The mentioned feature works like charm and we routinely use it for a long time (typically in a situation where we know that we are validating e.g. PDFA/1B and need to tolerate some minor deviation from the standard).

Our motivation:

However, the mentioned functionality does not cover the situation, when the PDF/A flavour is not known in advance (we need to use built-in automatic flavour detection) and we need to apply tolerance as in the above case.

The suggestion of solution:

As a possible solution, it seems to extend the command line with a one new switch (for example "-ps" as "profile set") whose argument would be a directory with a complete set of locally modified profile set, which would take precedence over the built-in.

Would you be willing to add such an option in one of the future releases of VeraPDF ?

@archive-uk thanks for the suggestion. We'll add this new switch to our roadmap to the next release

Hi @archive-uk we are still struggling adding this functionality into the veraPDF CLI, as it seems to be a custom logic that should rather be implemented as a script:

• first retrieve the coformance claim from the document metadata
• then choose an appropriate custom profile

The first item can already be done using veraPDF feature extraction.

I understand, this is not very convenient, as it requires parsing XMP metadata. So, we can add a feature type we extract from PDF, namely, the list of all conformance claims in the document. We can also provide you with a sample script that would implement the logic you need.
