I'm manipulating a pdf file that contains XMP meta data. When saved, the ModDate entry of the document information dictionary is updated, but not the <xmp:ModifyDate>-value in the document's meta data object stream. This makes the resulting document non-compliant with PDF/A.
Can I somehow set the <xmp:ModifyDate> to the same value as used for ModDate?
Thank you very much in advance for any help!
PDF/A and XMP is far beyond the scope of jPod.
What we do in our applications is set up a listener that watches for changes in XMP relevant parts. XMP is read/written using "jempbox" then... other XMP libraries should be around.
