Hi Moritz,
I must say that this is not very reassuring. So basically what we have
in this datatype now is a "LaTeX-like" markup language that is only
supported by one implementation that was created for MediaWiki, and
partially by a LaTeX package that you created.
Why did you not just use LaTeX? Do we really need additional commands
here? Just think about the interoperability of the data you are
creating. Just because some command alias is used on Wikipedia does not
mean we need it -- we can simply translate it to standard LaTeX on import.
The question about MathJax I asked because consumers of the data clearly
need some way to display this markup. MathJax is a widely used library
that can support this. Or maybe MathJax already supports your custom
extensions somehow (I am not that familiar with it)? If not, then what
other ways are there of embedding your custom math markup language into
my application?
Cheers,
Markus

Hi Markus,
it's not exactly a subset of LaTeX. Some commands were added some were removed.
A large portion of those parts are documented here
https://en.wikipedia.org/wiki/Help:Displaying_a_formula , and a complete list
is available from http://1drv.ms/1RtoZoW
For LaTeX users I created a LaTeX macro package so that they can copy and paste
texvc style LaTeX code to regular LaTeX documents
https://www.ctan.org/pkg/texvc
However, there are two issues with this package: \and and \or are not
supported by my LaTeX package since redefining those commands caused internal
problems. However, most of the time people use the standard LaTeX command \lor
and \land anyhow. Altogether, enwiki contains 969 \lor and 1581 \land.
Statistics on the usage frequencies are available from
https://gitlab.tubit.tu-berlin.de/data/wikiFormulae/tree/master
w.r.t 2) I have no idea how that relates to MathJax? Can you explain the
background of your question?
Best
Moritz

Betreff: Re: [Wikidata] upcoming deployments/features
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?
Cheers,
Markus

The string is interpreted by the math extension in the same way as the
Math extension interprets the text between the <math /> tags.
There is an API to extract identifiers and the packages required to
render the input with regular latex from here:
http://api.formulasearchengine.com/v1/?doc
or also
https://en.wikipedia.org/api/rest_v1/?doc#!/Math/post_media_math_check
_type (The wikipedia endpoint has been opened to the public just
moments ago) In the future, we are planning to provide additional
semantics from there.
If you have additional questions, please contact me directly, since

Documentation? What will downstream users like us need to do to
support
this? How is this mapped to JSON? How is this mapped to RDF?
It is a string representing markup for the Math extension. You can
already test it here: http://wikidata.beta.wmflabs.org/wiki/Q117940.
See also https://en.wikipedia.org/wiki/Help:Displaying_a_formula.
Maybe Moritz wants to say bit more as his students created the
datatype.
Cheers
Lydia
