Stefan Berger commented on FOP-3006: ------------------------------------ I've added the xconf and test.fo file, fonts have to be specified in the fop.xconf in order to to use PDF/A. Here is some code triggering the bug: {code:java} FopFactory fopFactory = FopFactory.newInstance(ResourceUtils.getFile("C:/Temp/fop.xconf")); try (OutputStream out = new BufferedOutputStream(new FileOutputStream(new File("C:/Temp/test.pdf")))) { Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, out); TransformerFactory factory = TransformerFactory.newInstance(); Transformer transformer = factory.newTransformer(); Source src = new StreamSource(new File("C:/Temp/test.fo")); Result res = new SAXResult(fop.getDefaultHandler()); transformer.transform(src, res); } {code} > XMP Metadata in created PDF/A-2 documents is not valid > ------------------------------------------------------ > > Key: FOP-3006 > URL: https://issues.apache.org/jira/browse/FOP-3006 > Project: FOP > Issue Type: Bug > Affects Versions: 2.6, trunk > Reporter: Stefan Berger > Priority: Major > Attachments: fop.xconf, fop_invalid_metadata.pdf, test.fo, > veraPDF-tempHTMLReport4387586169468085905.html > > > When you set the "pdf-a-mode" to "PDF/A-2a" and generate a PDF, it will not > pass the validation because <dc:language> and <dc:date> are not valid. > In the case of <dc:language>, it should contain a <rdf:Bag>, and <dc:date> > should contain a <rdf:Seq>. > The offending code is this one: > [https://github.com/apache/xmlgraphics-fop/blob/trunk/fop-core/src/main/java/org/apache/fop/pdf/PDFMetadata.java#L149|https://github.com/apache/xmlgraphics-fop/blob/678d6c0e04fd6a5464012be0241bb771cf9bb506/fop-core/src/main/java/org/apache/fop/pdf/PDFMetadata.java#L149] > By setting compact to true, Bags and Sequences are not created. > Attached you will find a PDF/A-2a file generated by Apache FOP and VeraPDF's > validation results.
