Description of the tool/project:
The JsonConfig extension allows other extensions to store their configuration data as a JSON blob in a wiki page.

Description of how the tool will be used at WMF:
The extension has been deployed to Wikimedia production for 5+years but with the introduction of Charts it is seeing renewed usage.

In T369950, @mmartorana pointed out that the json-config extension hasn’t been reviewed in some time (T163827, 5 years ago). I recommend conducting an updated review, as it plays a critical role in input validation.

Has this project been reviewed before?
Yes

Working test environment
The extension and the service are deployed in the beta cluster.

• Example chart definition page (which is a JSON blob when you edit it, but appears as a chart when you view it): https://commons.wikimedia.beta.wmflabs.org/wiki/Data:1993_Canadian_federal_election.chart
  • This uses the data from https://commons.wikimedia.beta.wmflabs.org/wiki/Data:1993_Canadian_federal_election.tab, which is a tabular data page. Tabular data pages are provided by the JsonConfig extension and are already available in production, see e.g. https://commons.wikimedia.org/wiki/Data:Election_results/May_2018_Ohio_Issue_1.tab
• For local testing, follow the instructions in the README file in the JsonConfig extension repo

Post-deployment
The Charts task force is responsible for this extension and is actively developing it. The main point of contact is Jon Robson (@Jdlrobson), who is filling in for Roan Kattouw (@Catrope)'s parental leave until late November / early December.
