Wiki development
I have been experimenting with mind maps and hypergraphs. I have downloaded Freemind and started to make some mind maps for the different systems of the body.

There is an extension to display mind map mm files created with Freemind in either flash or Java but for the time being I have gone with the simpler option of taking a screenshot of the mindmap and saving the section as a png file and uploading the png file to Rejuvepedia.

Here is an example:



The red icons with the white strip denotes that the page requires development.

I didn't go the way of installing the freemind extension because basically that didn't really make it much easier for people to collaborate either.

Looking at the discussion page for the freemind extension I have seen that a better option may well use text in the wiki specifying parent and child relationships and build the mindmap using that. That will make improve collaboration but at a cost of making the mindmap editing process less visual.

I am also looking into Hypergraphs and the Semantic graph extension. The hyper graph is really neat check out: http://semanticgraph.sourceforge.net/

The hypergraph is the third graph on that page. You can use your mouse to select and zoom into parts of the hypergraph and explore sections and branches in more detail.

To use the Semantic graph extension it says we need:  Semantic mediawiki Semantic Forms Graphviz 

http://www.mediawiki.org/wiki/Extension:Semantic_Graph

At the moment Rejuvepedia is not a semantic wiki. The idea of making Rejuvepedia a semantic wiki sounds really cool and could probably make it much more robust and powerful. It would be a big jump from what we have now though and I would test all of this stuff on a separate installation before going live on the main website.

Collaboration and outreach
Still on the subject of hypergraphs it has struck me that I don't know of anyone that has made a hypergraph of the human anatomy. I did a little google searching but could not find one. It is something that Rejuvepedia could really benefit from and so could other projects as well. I could perhaps try to get in touch with people from anatowiki to see if this is a project we could collaborate on.
