Meanwhile I stumpled over
https://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
but haven't found the time (and mood!) to test it.
it fails for pdf/a-1a with the test.pdf made by context Validating file "test.pdf" for conformance level pdfa-1a Invalid content of XMP packet header attribute 'id': 'frpyaihfvjcmxbxoohwuhyjt'. pdfaExtension:schemas/*[0] :: Missing required field 'valueType' in value type 'Schema'. pdfaExtension:schemas/*[1] :: Missing required field 'valueType' in value type 'Schema'. pdfaExtension:schemas/*[2] :: Missing required field 'valueType' in value type 'Schema'. pdfaExtension:schemas/*[3] :: Missing required field 'valueType' in value type 'Schema'. pdfaExtension:schemas/*[4] :: Missing required field 'valueType' in value type 'Schema'. The document does not conform to the requested standard. The document's meta data is either missing or inconsistent or corrupt. Done. while verapdf and acrobat (Preflight, 11.0.16 (120) Acrobat version: 11.018) both say that the file is ok. -- luigi
