The gnowledge.org lab of Homi Bhabha Centre (HBCSE) launched a new community portal on 31st October 2008 to make concept maps of all areas of knowledge. Currently there are about 400 concepts with about 350 prerequisite relations among them.
The activity is to build a road map of knowledge by establishing dependency relations (prerequisites) between concepts and activities. Soon we will extend the site for TypeMap, PartMap, InteractionMap, ProcessMap, CauseMap, functionMap, TestsMap, TranslationMap etc. That way progressively and collaboratively we can represent all knowledge as concept maps.
The current map looks like this.

The site is waiting for community contributions and suggestions at

What is the best email to contact you regarding knowledge and concept mapping.
Currently we are working on about 1000 concepts for math and also plan on mapping all basic subject matter courses and supporting with research tools to speed up learning.
Please let me know the best contact information so we may discuss ideas for indexing and graphically representing the information.
Thank you.
