An investigation task for wish #6, Article alerts for more languages. From the wish proposal -
> **Problem:** [Article Alerts](https://en.wikipedia.org/wiki/WP:AALERTS) is an automated subscription-based news delivery system designed to notify WikiProjects and Taskforces when articles tagged by their banners or placed in their categories enter various formal workflows (such as Articles for Deletion, Requests for Comments, Peer Review, and many more). See [WikiProject Physics/Article alerts](https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Physics/Article_alerts) for example. This is currently an English-Wikipedia exclusive, and is maintained by one user (en:User:Hellknowz), meaning the [bus factor](https://en.wikipedia.org/wiki/bus_factor) leaves the whole project in a fragile state.
> **Who would benefit:** Every edition of Wikipedia. For scale, on the English Wikipedia, 1467 WikiProjects and Taskforces subscribed to the Article Alerts system. Virtually every active project is subscribed, and the system is one of the best lines of defense against improper deletions and one of the best ways to advertise ongoing high-level discussions to communities of interest.
> **Proposed solution:** Have the WMF / larger Wikimedia community create a more solid and scalable framework for Article Alerts that can also be deployed to all languages. Maybe it's not possible to have something as customizable as the English Wikipedia's implementation, but there are loads of things that could be ported and deployed. (Edit: See [en:Wikipedia:Article alerts/Roadmap](https://en.wikipedia.org/wiki/Wikipedia:Article_alerts/Roadmap) for a tentative roadmap.)
Notes on the project page:
For the investigation:
* Look at the source code provided by Hellknowz. (see email) Look at how workflows are implemented in the existing bot. (Note that the code is in C#)
* Determine if there are [current workflows](https://en.wikipedia.org/wiki/Wikipedia:Article_alerts#Workflows_covered) that are standard across several wikis. How many can be described?
* Take a look at [PageAssessments extension](https://www.mediawiki.org/wiki/Extension:PageAssessments) which maintains a database table for pages associated with wikiprojects and their quality assessments. Could the extension possibly be useful here (with or without changes)?
* Could this be an extension instead of a bot?
* Can we think about making this work without wikiprojects but use categories instead? (Suggested in the proposal discussion)
* Determine which wikis want this and would benefit (use WikiProjects or something equivalent)?
