Re: [Wikidata-tech] MathML is dead, long live MathML
Hi Daniel, Ok. Let's discuss! Most interesting for me is Peters statements > Content MathML is just not relevant. Since I'm currently investigating how content MathML is used, and whats needs to be done to get mathematical content from one system to another. Currently, I have the impression that the latter question is completely solved in theory, but completely unsolved in practise. Disclaimer: While I really appreciate drinking beer with Peter, we have slightly different approaches for de facto standards to share mathematics in information systems.

Re: [Wikidata] upcoming deployments/features
The string is interpreted by the math extension in the same way as the Math extension interprets the text between the 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 I'm not a member on the list.

[Wikidata-l] Modeling identifier definitions
Hi, I have one question concerning wikidata: at http://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation#Time-dependent_equation we have the statement Ψ is the wave function I have developed a system that discovers the relation between Ψ and the page wave function Is there a way to model that in wikidata or should I use another way to model that relationship? If so could someone show me how to model the relationship from the example above. Best Moritz PS: Linking to the variables can either be done by xpath, or I assigned a number starting from 1 for all math/ tags. That said a possible link to the first equation could be specified by adding #math1 to the url.
