Hi,
I'm trying to add Zugferd (http://www.ferd-net.de/) electronic invoicing
metadata to a PDF/A-1a created with OpenOffice
PdfBox (snippet attached) helps me to "convert" it to PDF/A-3a in a
first step, which seems to work, at least
http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx validates.
In the second step (based on
http://pdfbox.apache.org/cookbook/workingwithattachments.html) I try to
embed a file but then the validator tells me
<<
The key UF is required but missing.
The content of the stream must not be in an external file.
The key AFRelationship is required but missing.
File specification 'Test.txt' not associated with an object.
>>
How do I get the content of the stream embedded (not "in an external
file") and do I need / how do I get the file specification 'Test.txt' to
be associated with the according object?
Is there a way to specify the UF key or AFRelationship ?
The UF key seems to be a unicode version of the F key and
for AFRelationship I would like to specify a "source" relationship.
Or maybe anybody has any example where I could have a look?
thanks a lot in advance (and happy holidays)!
Jochen
