Hi, I want do develop functionality to create PDF/A-3 level document. But I am not sure what are the properties I need to set with what values. Also I need to set Dublin Core elements metadata for each PDF/A file.
I referred sample class at: https://apache.googlesource.com/pdfbox/+/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/CreatePDFA.java to create Document, but in some sites they said document is not valid. So tried one more class found at: https://github.com/jstaerk/mustangproject/blob/master/pdfa3-sample/src/main/java/pdfbox/PDFA3File.java Using this class I can create document successfully and also during validation on online tool, it is verified as proper document. So main questions are: 1 ) What are the properties I need to set with what values to create correct PDF/a-3 document having DublinCore metadata? 2) How to validate that document I have created using PDF Box is correct and as per PDF/A standard?
