The following standard document information dictionary keys are read-only: "Producer", "Created", and "Modified"; the library will overwrite the values of these keys on document save.
See Section 10.2.1 on Info dictionaries in the PDF Reference for information about Info dictionaries. All values in the Info dictionary should be strings; other data types such as numbers and Booleans should not be used as values in the Info dictionary. If an info dictionary key is specified that is not currently in the info dictionary, it is added to the dictionary.
