The Simile Timeline for Rails project provides a set of tools for Ruby generally, and Rails specifically to generate Simile Timeline DHTML controls in pages, and produce and consume events for display within those timelines.

It provides a two view portions, the first of which generates DHTML + JavaScript powering the timeline and fielding events to a remote server, and the second which generates JSON-formatted events consumable by the timeline. It also provides an ActiveRecord mixin which allows existing Rails model instances to expose themselves as Simile Timeline events.
