APA Use Case: Support accessibility on complex embedded objects

[JaninaSajka]

Many publications and especially textbooks will include specialized content unlikely to expose sufficient accessibility support. While there numerous available examples from any academic speciality, we illustrate the general issue by the example of scored music. A harmony, counterpoint, or composition textbook, a title in music history, as well as a common hymnal will each contain many scored music examples or even complete musical scores along with the text words possibily associated, e.g. as in a hymn or a song. The common general purpose browser or ebook reader is unlikely to provide features rich enough to sufficiently examine and learn the content. Note that displaying scored content is insufficient. Simply causing audio playback is similarly insufficient. Yet tools exist that are able to support the required feature sets. Our problem therefore is to work out how to allow sufficiently capable tooling to function within the general purpose ebook reader or browser.
