Ability to store raw data into target wikipage

[hugolpz]

Feature request which may or may not be within your scope.

Use case
I want to create an user script datavizualisation via coding a MediaWiki:Mydataviz.js and wikidata-fetched data.
Some of my sparql queries are reaaaaallly slow (30~60s). We can't let the visitor wait that much for the dataviz to load and display : we need to periodically store and update our data into some MediaWiki:Mydata.js page. MediaWiki:Mydataviz.js would then rely on this data to generate the dataviz in less than a second.

It could be used for advance dataviz such as the map, or advances stats. Etc.

New parameters required

• format, ex : "json", "xml", "csv", etc.
• target page, ex: MediaWiki:Mydata.js
