SUL finalisation/Renaming requests design

This document describes the design for several components related to the SUL Finalization project.

Rationale
Approximately 4.3 million user accounts will require renaming across all Wikimedia projects. The normal mechanism for supporting renames or usurptions utilizes an arcane process of templates and volunteer time which will not scale easily (if at all).

This system seeks to address this problem while allowing individual users agency. There are multiple parts to this process, not all of which are visible to end users.

Problems

 * Non-SUL'd accounts cannot request renames on meta (which is the normal mechanism for doing so) as they may not have an account on meta.
 * Non-SUL'd accounts may not have email addresses associated with them.
 * Some users may not recieve notification that they will be renamed and the process will happen without their intervention. They must be informed that they have been renamed, and must also be allowed to log in to their former wikis using older credentials (which must then expire).

User Stories
They are very simple:


 * As a user who is going to be forcibly renamed, I would like to request a new name through a self-serve process on my home wiki and in my own language.
 * As a user, I do not want to lose access to my account.
 * As a user, I wish for this process to be as painless as possible.
 * As a steward, I want to have an easy-to-use, scalable interface from which to handle the Global Rename queue.
 * As a steward, I require the ability to suppress individual entries in the rename log.

Work Phases and Project Scope
The initial scope of this project is focused entirely on the SUL Finalization requirements.

That said, a second iteration of the project could be initiated that will make the rename request system more robust and flexible, usable in the future for all rename and usurption requests, with little effort.

The Rename Request Queue
This is a database table that stores pending and completed requests. It should contain the following fields:


 * Current/Old Username: The username of the user requesting the rename. This may not be an SUL username.
 * Requested Username: The new, requested username. This is unique.
 * Local Wiki: The wiki that the request originates from.
 * Request Time: A datestamp when the request was filed.
 * Status: Pending, Completed, or Rejected
 * Done By: The name of the Steward who closed the request
 * Comment: A text comment left by the steward upon closing the request. Optional, but assumed with rejections.
 * Rationale: A future element, this would be the rationale given by a user for the rename request. Not included in phase 1.

Special Pages
Note: the names of these special pages may be changed; I'm not married to them at all.

Form Elements

 * Requested Username: This is a "smart" field. After data has been entered and the field loses focus (onblur), an AJAX system will start checking to determine if the given username is available.  A username's availability is checked against two databases:  The existing SUL username list and the


 * Email and Confirm Email: The form requires an email address to be completed. The reason why we are requiring an email at this point in time is because we do not want users to lose access to their accounts in case something goes wrong and they will be able to reset their passwords normally.

Special:GlobalRenameQueue


Note that these screens have slightly different appearances if they are viewed by Stewards or not.

Special:PostLoginRename
This screen is a variation on Special:GlobalRenameRequest. This is the screen that users see who have been renamed without their knowledge.

These users will log in to their home wikis using their old username and password. Once they have logged in, they will be given a notification (very big and bold) that they have been forcibly renamed. They will also be presented with the rename request form in case they wish to ask for a new name.

If they do, the process proceeds as above. If they do not, they can cancel out of it.

TODO: Mockups.

Changes to Special:CreateAccount
Names included in the "reserved names list" must also be checked here for available usernames. Currently, the form only checks against the SUL account list.
