The descriptor alternativeModes is a catch-all container field that indicates the presence of one or more alternatives to the primary visual, audio or textual presentation or display for a media item. The actual content of the alternative track or mode is not entered here.
The alternative modes that are encountered most frequently include:
• DVI: Descriptive Video Information
• SAP: Supplementary Audio Program
• CC: Closed Captions
• OC: Open Captions
• Caption Track
• Subtitle
• Dubbed
• Transcript
• Audio (the main or secondary audio tracks, as in DVDs)
The WGBH National Center for Accessible Media (NCAM) is working with the IMS Global Learning Consortium to publish a specification: Accessibility for Learner Information Package (LIP). This specification and metadata schema is intended to address user needs and preferences for alternative presentations of content found in a media item.

In the interest of simplicity, UMAP will not be folding in the accessibility metadata at this time. However, we have created this container field called ALTERNATIVE MODES into which equivalent alternatives to what is seen, heard, and read can be identified, along with the language associated with that mode.
There may be more than one alternative track found in a media item; each needs to be identified.
Because various alternative tracks may use a different language than the primary language of the media item (see the descriptor language), PBCore recommends that the alternative language associated with an alternative track be identified as well. The structure of your data entry should be:
• Identify the alternative mode for seeing, hearing, or reading the content for a media item,
• Followed by a space,
• Followed by the word "in",
• Followed by another space, and...
• Append the language for that alternative mode.
If there is a second alternative mode, end the first indicator with a PERIOD, then a space, and follow that with the next indicator.
