NooronNoobj was an experiment in interactive graph layout of knowledge. It was built on a re-interpretation of the OKBC formalism. This Nooron prototype featured self-hosted semantic-oriented programming and knowledge management along with real-time collaborative ontologizing through a graph visualization.

The stack was thoroughly 201x (Node.js, D3.js and WebSockets) but the semantic aspect was a revisiting of the OKBC. In that way it harkened back to the PerlJavaIdeaEngine I wrote back in 1998. What an improvement in web standards we enjoy these days relative to the turbulence of the Browser Wars era!
Learning: This version had lots of great stuff about it, including that it enabled the collaboration on HuViz with the OrlandoProject. Henceforth HuViz consumed my available time and also convinced me that full OWL/RDF compatibility was worth settling on vs continuing with "noobj" OKBC semantics.
