For a consumer, the main practical questions would be:

(1) What subset of LaTeX exactly do you need to support to display the math expressions in Wikidata?
(2) As a follow up: does MathJAX work to display this? If not, what does?

There is an API to extract identifiers and the packages required to
render the input with regular latex from here:
or also!/Math/post_media_math_check_type
(The wikipedia endpoint has been opened to the public just moments ago)

        Documentation? What will downstream users like us need to do to
        this? How is this mapped to JSON? How is this mapped to RDF?
