Users can use one account to log into any wiki (Single User Login - SUL), obscuring the fact that MediaWiki's legacy implementation requires separate accounts on each wiki. CentralAuth is a centralized database of accounts that links a user's accounts across wikis.
CentralAuth documentation: https://www.mediawiki.org/wiki/Extension:CentralAuth
We want wikimetrics reports to include users’ activity on other projects without having to research their account names on each project/wiki.
Program manager has a list of wiki users in a CSV file. Some users in this cohort are active across various wikis (let’s call them CentralAuthUsers). The program manager wants to run reports against her list of users and - for the CentralAuthUsers - include their accounts on other wikis in the new cohort on wikimetrics.
For example, I used CentralAuth and created the accounts FooBar on both enwiki and frwiki. If the program manager has only one of my accounts (FooBar|enwiki) in her CSV list, when she uploads the CSV to create a new cohort, she has the option to include all other accounts in CentralAuth associated with FooBar|enwiki. So in the end, the cohort will include both Foobar|enwiki and Foobar|frwiki.
As a program manager,
I can select the checkbox labeled XYZ when uploading my cohort,
so wikimetrics will automatically add CentralAuth users’ accounts from other projects
- the only time user sees this is when uploading a cohort. No other references to CentralAuthUser are necessary.
- The UI does not need to distinguish cohorts that include accounts taken CentralAuth
- short form: program manager checks “expand...” when uploading cohort
|1||☒ Expand cohort to include accounts of users who are known to have accounts in other projects.|
|2||☒ Add to cohort user’s accounts in other projects (given by CentralAuth)|
|3||☒ Find and include user’s accounts in other projects (given by CentralAuth)|
|4||☒ use CentralAuth to add a user’s accounts in other projects to this cohort.|
|5||☒ Expand cohort to all user’s accounts across projects (via CentralAuth)|
