Schema term braille

[chrcarr]

Schema definition of term braille - [1] The content is in braille format, or [2] alternatives are available in braille. Note: Information about the type of braille (e.g., ASCII, unicode, nemeth), whether the braille is contracted or not, and what code the braille conforms to should be provided in the accessibility summary.

Having two possibilities is ambiguous.

[1]. Does this refer to print braille or electronic braille? If both, then the term is doubly ambiguous.

[2]. Are the alternatives provided in print braille or electronic braille? Again ambiguous.

Action: There should be separate terms for print and electronic braille.

schema.org metadata can be used to describe print resources, but even then I don't think it's particularly useful to have a braille value. I'd expect you can determine if it's a braille book by the format information. Braille fallbacks for visual content also seems unlikely outside of a digital braille format.

Similarly, information about the type of braille may not be necessary to encode in the summary. That depends on whether there is already metadata for this or not.
