If metadata does not contain XMP properties belonging to the Rights Management scheme, the method returns null.

If the metadata does not have Rights Management XMP properties, and you need to add such properties, create a new instance of the com.accusoft.imagegear.formats.xmp.rightsmanagement.ImGearRightsManagementXMPMetadata class, assign it to this property, and then add XMP properties using corresponding properties of the com.accusoft.imagegear.formats.xmp.rightsmanagement.ImGearRightsManagementXMPMetadata class.
