Interesting post on a first experience with Neo4j:
There are many cool things that have emerged over the last few years that I’ve wanted to play with but not had a real reason to. One of these is Neo4j, a graph database; another tool to emerge from the “noSQL movement”. Well, when I was younger, I spent a LOT of time playing on MUDs (indeed, it was this that provided me with my first opportunity to write Real Code); for those who haven’t experienced them before, a common MUD family (ROM) has a movement system that consists of Rooms, discrete locations with a number of Exits to other rooms. Hey look ma, a graph!
Looks like another MUD engine is under development!
