-----------------------------------------
Summary: PDF with creator does not conform to PDF/A-1b although
PDF/A-1b is requested
Key: FOP-2662
URL: https://issues.apache.org/jira/browse/FOP-2662
Project: FOP
Issue Type: Bug
Components: renderer/pdf
Affects Versions: 2.1
Environment: all
Reporter: Agneta Walterscheidt
Priority: Minor
A PDF file that is created with FOP as PDF/A-1b does not conform to PDF/A-1b
when a creator is set in the FOUserAgent. This is due to the fact that the
XMPSchemaAdapter's allow a "compact" format which means that array elements
(sequence and bag) will only be written as such (i.e. within <rdf:Seq> and
<rdf:li> tags) when then array contains more than one element. The default is
compact=true and this is not changed by FOP's IFRenderer.
This is wrong at least for the creator in PDF/A-1: the creator must be given as
one and only element of a sequence - see for instance
https://www.pdfa.org/wp-content/until2016_uploads/2011/08/tn0003_metadata_in_pdfa-1_2008-03-182.pdf:
"Author
If the Author entry (of PDF data type text string) is present in the document
information dictionary, the document’s Metadata must contain an equivalent
entry dc:creator of XMP data type seq ProperName where dc refers to the Dublin
Core schema (the prefix is actually arbitrary). While dc:creator is defined as
a seq type in XMP, in PDF/A-1 this sequence must contain exactly one entry."
