Summary: "XMP type violation in stRef:instanceID" not reported by
preflight
Key: PDFBOX-2643
URL: https://issues.apache.org/jira/browse/PDFBOX-2643
Project: PDFBox
Issue Type: Sub-task
Components: Preflight
Affects Versions: 2.0.0
Reporter: Tilman Hausherr
In the Bavaria test suite, PDFLib claims that the attached file is not a valid
PDF/A-1b file, because "Property stRef:instanceID in document XMP requires
scheme identifier" or "XMP type violation in stRef:instanceID" (They make both
claims in Bavaria.xml).

PDF-Tools considers the file to be correct. But according to
http://www.pdflib.com/fileadmin/pdflib/pdf/pdfa/2009-05-04-Bavaria-report-on-PDFA-validation-accuracy.pdf
they don't raise the correct alarm for XMP violations. The PDFLib xmp checker
also considers the XMP to be correct.
"6544a661-c065-11dc-854c-dd4f35453e8b" does not look like a valid URI to me
although the regex mentioned at http://tools.ietf.org/html/rfc3986#appendix-B
thinks it is.
[~msahyoun]what do you get for that file? The Bavaria Testsuite is already 5
years old, so maybe Adobe/Callas have improved their product.
(Another unreported error for that file is "xapGImg:height for xmp:Thumbnails
in document XMP does not match the actual base64-encoded image data")
