Aeon Timeline is more like an abstract temporal entity management program. I t happens to use a visual timeline, but it allows for conceptual linking of people, places, events in a rather clever fashion. It is intended for brainstorming and collecting via flexible input and export.

With Aeon, you can divide your timeline into logical groups, projects, or concurrent arcs. You can model the relationships between events and people, places and ideas. Aeon calculates people's ages for you. And you can link your events with research material such as external files or images that can be displayed inside the application.
