Initiative Vision

< Initiatives

Vision: Actors mentioned in page history or log entries can be represented by lightweight value object
Stakeholder(s): MediaWiki developers (core and extensions) will benefit from clearer, more testable code Extension developers (in WMF and elsewhere) will have more control over the behavior of pages their extension manages. Quality + test engineering may be interested since we are making code more testable by removing special cases throughout the code base	Problem: The User object is huge and has sprawling responsibilities We need a simple entity type for representing actors across domains We need serializable value objects to represent actors in events and and queues.		Solution: Introduce an ActorStore service that can be used to instantiate UserIdentityValue objects based on rows in the actor table	Aligned Goals: Improve code quality by reducing coupling Improve code health by improving testability Improve maintainability by modeling domain concepts clearly	Success Metrics:
