Wiki Timelines
Dipity
Intro
Dipity is an AJAX web application based on MIT’s SIMILE Timeline. It can accept web feeds like xml/rss and output a user modifiable timeline. Because it accepts normal RSS, it works with a wide range of media, allowing the user to create mashups with YouTube as well as Flickr.
How-to
Prior to creating a timeline, you must have an account with Dipity. This allows for access control. To create a timeline, simply select create a timeline from the top menu. You will be required to enter the title, description as well as select a category for your timeline. Optional info like the timezone, picture icon and permissions can be set as well. Click on create timeline. Once the timeline has been created, you can add RSS feeds by clicking manage sources. You’ll have a choice of a large number of sources, from youtube and picassa to flickr. For custom feeds you can click the RSS button and enter the corresponding URL.
Examples
Mnemograph
Intro
Mnemograph is a Flash based web application that can also create dynamic timelines from xml/rss sources. Because it uses flash, Mnemograph’s interface is cleaner and more cohesive compared to Dipity. Unfortunately, there are fewer mashup options, as importable media is limited to only photos. Nevertheless, the cleaner interface makes Mnemograph a compelling choice.
