Hi, 1) thanks 2) This seems to use xmpbox, I did not know there were two XMPMetadata at all (org.apache.xmpbox.XMPMetadata and org.apache.jempbox.xmp.XMPMetadata) and so far I used jempbox.
I read from http://mail-archives.apache.org/mod_mbox/pdfbox-dev/201308.mbox/%3CJIRA.12534142.1323239234412.56576.1377812391819@arcas%3E that jempbox seems to be deprecated and I should rather use XMPbox. But somehow I can't find any clue how this should be done, more precisely, how to write xmpbox metadata to the document? I so far use the jempbox way(?) PDDocumentCatalog cat = doc.getDocumentCatalog(); PDMetadata metadata = new PDMetadata(doc); metadata.importXMPMetadata(xmp); but importXMPMetadata does not seem to accept a XMPbox metadata, neither can I cast it or see any way to convert. Please advise, thanks and kind regards, Jochen Am 09.04.2014 10:45, schrieb Maruan Sahyoun: > Hi, > > PDFAExtensionSchema is meant as a start for PDF/A-1 Extension Schema > Container Schema. > > BR > Maruan Sahyoun > > Am 09.04.2014 um 10:20 schrieb Jochen Staerk <[email protected]>: > > Hi, > > I am trying to support a standard which adds information in the RDF > metadata.
