MetadataCustomEntries Property

The custom entries in the document information dictionary

The standard entries "Title", "Author", "Subject", "Keywords", "CreationDate", "ModDate", "Creator", "Producer" and "Trapped" are not included in the map. Any attempt to set a standard entry through this map will result in an error. To get or set standard entries use the corresponding properties instead.

Note: The document information dictionary has been superseded by XMP metadata and is deprecated in PDF 2.0.
