Notifications/Data model

Draft only

Introduction

There are four key data objects required to maintain Echo in its initial state:

• An event type (is there a better name?) is a type of event that can occur. For example: "talk page edited", "article expanded", etc.
• A subscription describes the relationship between a user who wants to receive notifications about events.
• An event is a specific instance of an event type.
• A notification ties a user to an event.
