I am preparing my thesis for PDF/A validity. I managed to produce a PDF that leads only one error in veraPDF, as follows:
The error is not regarding the document itself but XMP metadata.
I found out that the xmpRights statement is created always, regardless how the directives \copyright, \copyrighted in .xmpdata are set. As soon as no copyrighturl is provided, an empty xmpRights statement is generated by pdfx in the pdfa.xmpi, leading to the error veraPDF reports. Is there a possibility of not generating the xmpRights statement?
