Re: Language Shifts (Accessibility, metadata)

I don't know what your schema looks like now, but there are a number of
well-used ways to specify language in schema.org.  The most common would
just be http://schema.org/inLanguage with a or multiple language codes.  I
can't guarantee anyone would consume it, but that would be the
most straightforward approach.

See an example from Apple:
https://validator.schema.org/#url=https%3A%2F%2Fitunes.apple.com%2Fus%2Fbook%2Fthe-devils-kiss-series-boxed-set%2Fid1205303225%3Fmt%3D11%26at%3D1001l6j9
