Read and write PDF metadata (Title, Author, Subject, Keywords, Creator, Producer, creation/modification dates). Import/export metadata via XML or map it into PL/SQL record structures.
Export PDF form data to FDF/XFDF and import FDF/XFDF into existing forms. Set fields to read-only and control NeedAppearances for consistent rendering across PDF readers.
