CHANGES TO TASK DESCRIPTION
Currently, we only export the MathML representation to Wikidata Query Service of a formula to RDF, not the original TeX string (T126349). This makes it impossible to efficiently query for statements with a certain math value – you have to use `REGEX` (`CONTAINS` is not enough, because the TeX annotation embedded in the MathML is not identical to the original TeX string). It also means that any external application that wants to use the TeX string based on the RDF export must use an XML parser to analyze the MathML and extract the TeX annotation.
See T126349#2014848 for more information.

I think we should add full value nodes for math values, with a structure a bit like this:
```
The string as input in Wikidata (whatever format) should to be available on Wikidata Query Service. Currently it's in the json format, but not on WQS. See T126349#2014848 for more information---
```

Side note: the “math” datatype currently seems to be missing completely from the [RDF Dump Format](https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format) page – once we’ve implemented this, we should rectify that.```
