An asset-only update should only consist of a short metadata file along with the assets. All metadata must be correct and complete, and the <assets> block should be included referencing any assets to be added, replaced, or removed.
In the first example below, the full asset is being replaced and a new alternate audio file is being added.
<?xml version="1.0" encoding="UTF-8"?><package xmlns="http://apple.com/itunes/importer" version="film5.3"> <provider>Paramount</provider> <assets media_type="video" vendor_id="09736156444"> <asset type="full"> <data_file role="source"> <locale name="en-US"/> <file_name>09736156444-source.mov</file_name> <size>2595225600</size> <checksum type="md5">39b499112fe8aa29dd7a793a8b46037a</checksum> <attribute name="crop.top">0</attribute> <attribute name="crop.bottom">0</attribute> <attribute name="crop.left">0</attribute> <attribute name="crop.right">0</attribute> <attribute name="image.textless_master">true</attribute> </data_file> <data_file role="audio"> <locale name="de-DE"/> <file_name>audio_DE.mov</file_name> <size>4916659</size> <checksum type="md5">9df86c3e43e7b43ddeabb2ddfe4b8a42</checksum> </data_file> </asset> </assets></package>The example below shows an update to a film that was previously delivered without closed captions and with the <accessibility_info> set to ARCHIVAL_CONTENT, which is no longer supported. In addition to updating the video asset, this update includes the closed captions asset file.
Note that if you send an asset-only update and captions are not available, you can include the <accessibility_info> tag within the <asset> block.
