A practical guide

Verify the saved fields against the source record.

  1. Choose a PDF and use Read metadata fields to load the current values.
  2. Change the title, author or other standard field; leave fields unchanged when appropriate.
  3. Save the metadata copy and inspect the latest PDF result.

Try this example
