Project Ideas

This page lists projects that could be a good fit to implement using neo4j.

Social Mind Map webapp. Let users connect nodes in their mind maps to nodes in other users mind maps as well.
Project Management webapp. Let users connect different items in a flexible way.
Social Network Analysis. Basic graph algorithms are already implemented (see Graph algo), and it's easy to implement your own on top of neo4j.
Stuff like Muckety news is a perfect match to neo4j.
Version Control System. At least a server part of one. It would be cool if it could interact with existing clients, such as mercurial or git.
Analysis and search of news and how they spread through social networks, e.g. Twitter (where does information come from, via which nodes does it spread, how fast etc)
Loosely couple Neo4j instances, e.g. mobile devices running Neo4j talking to each other and connecting their node spaces, some social fabric app to showcase it
Implementation of a set of Neo-Java-annotations allowing POJO-BEANS to be promoted to Neo nodes and relations: In essence a paradigm for mapping POJO-BEANS to Neo-entities by means of Java-annotations: @NeoNode, @NeoRelation applied to "inner" node, "inner" relation (very much like with JAXB).
Recommendation Engines seem to profit from the structure as well. People who bought this also bought that.
GIS support making Neo4j a fully featured spatial database: Neo4j Spatial
