Timeline service module

Wandora's timeline service module is used to visualize RSS, Atom, Email , New York Times events API, New York Times article API, Oma kaupunki,YouTube and Twitter extractions. The timeline service module is based on the Simile Timeline project. Wandora transforms extracted topics and association into Simile Timeline JSON format and passes created data structure to Timeline Javascript library. Timeline service module's alias is timeline. Using the timeline module requires that the Wandora's embedded HTTP server is started and the module is activated. Timeline's URL is

http://127.0.0.1:8898/timeline

The timeline service module demonstrates how to build an HTML and Javascript visualization that uses Wandora's topic map API. It is a known issue that many other Wandora extractors would also work nicely in timeline visualization. We welcome extensions to the timeline service module.

Example

In this example the Wandora user starts Wandora's Twitter extractor by selecting menu option File > Extract > Social > Twitter extractor and performs a Twitter extraction using hashtag #topicmaps. Then user starts Wandora's RSS 2.0 extractor by selecting menu option File > Extract > News > RSS 2.0 extractor and performs an RSS extraction from URL http://www.nytimes.com/services/xml/rss/nyt/Technology.xml. Finally Wandora user starts Wandora's embedded server by selecting menu option Server > Start server and opens timeline service module with menu option Server > Browse services > View service timeline. Wandora opens up a WWW browser with address http://127.0.0.1:8898/timeline. WWW browser reads Wandora application generated WWW page containing an interactive timeline visualization. User can browse the timeline and look at Twitter and RSS events interleaving.
