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

If the metadata does not have Media Management XMP properties, and you need to add such properties, create a new instance of the com.accusoft.imagegear.formats.xmp.mediamanagement.ImGearMediaManagementXMPMetadata class, pass it to this method, and then add XMP properties using corresponding properties of the com.accusoft.imagegear.formats.xmp.mediamanagement.ImGearMediaManagementXMPMetadata class.

If you need to remove Media Management XMP schema properties from the metadata, set this value to null.
