Ike Wiki

First of all, you just have to love the name (and connotation).

From wikipedia:
A Semantic Wiki is a Wiki that has an underlying model of the knowledge described in its pages. Regular wikis have structured text (in this article: Introduction, Example, ...) and untyped hyperlinks (the links in this article). Semantic Wikis allow the ability to capture or identify further information about the pages (metadata) and their relations. Usually this knowledge model is available in a formal language, so that machines can (at least partially) process it. The technologies developed by the Semantic Web community build the basis for reasoning about the knowledge model.

In particular, machines can calculate new facts (e.g. relations between pages) from the facts represented in the knowledge model.


Interesting to watch, in my opinion, the next generation evolve...
