Seriously I started development of e-mentality in 2002. Since that time I have created two prototypes and now I'm going to start implementation of the third one - codenames follow:
Cognition Organizer era started by months of analytical work. I suspected what I want to create, but didn't know how it should look like and how it can be implemented. I considered various languages and platforms. Finally I decided to create Java application based on Melnik's RDF API and Touchgraph library. The first prototype brough a convenient abstract model for cognition outlining.
After analytical review of CognOr, I changed my mind regarding to the most important technical topics mainly related to REST-wise resource design, metadata vs. data, RDF incorporation and outline rendering functionality (main UI level features). In fact, I created the second prototype almost from scratch. It was based on Jena and significatly improved Touchgraph library.
During the implementaion of MindRider I learnt that rendering of a general graph in Touchgraph manner can be cool, but it's confusing and in some cases even unusable (hugo models). I considered various approaches e.g. Grokker like or Personal Brain like, but finally I decided to use very simple and fixed form that would be very close to some textual representation (its design is still in progress). Also I changed my mind on architecture of the e-mentality - mainly regarding to location of the user data (cognition) - Google desktop release was the final impulsion.
Now I'm analysing Vodyanoi - the third e-mentality prototype. Apparently it will be realized as a server/thin client framework (ensuring that cognition will be accessible anywhere from any (even small) device and accessible using current web browsers - rendering of stored cognition in very simple and almost textual synoptic form; providing a customizable way allowing to acquire convenient representations of resources (cognition entities) via XHTML & CSS (& XSLT) combination. Resource type system and templates will make using it efficient; and the overall architecture will enable e-mentality riders to share their cognition bases in a collaborative environment.
Although I'am analysing Vodyanoi, I'am building MindRaider :-) In order to prepare Vodyanoi release I abused MindRider - it is now renamed to MindRaider. In fact Vodyanoi will be built on top of MindRaider kernel - MR as server providing REST style HTTP access to resources. Screenshots and kernel details are comming soon...
