Looking for something fun to do during the holidays? Here are a few suggestions for some new cool Neo4j things that you can play around with.
Neo4jr-Social is a self contained HTTP REST + JSON interface to the graph database Neo4j. Neo4jr-Social supports simple dynamic node creation, building relationships between nodes and also includes a few common social networking queries out of the box (i.e. linkedin degrees of seperation and facebook friend suggestion) with more to come. Think of Neo4jr-Social is to Neo4j like Solr is to Lucene.
Neo4jr-social is built on top of Neo4jr-simple:
A simple, ready to go JRuby wrapper for the Neo4j graph database engine.
Simple object mapping for neo. No byte code interweaving, just plain old reflection and plain old objects.
There's also a blog post where Taylor shows how to model a User/Roles pattern using jo4neo.
There's apparently a lot of work going on right now in the Django camp to enable support for SQL and NOSQL databases alike. Tobias Ivarsson (who's the author and maintainer of the Neo4j Python bindings) recently implemented initial support for Neo4j in Django. Read his post Seamless Neo4j integration in Django for a look at what's new.
One more recent project is the Neo4j plugin for Grails. There are already some projects out there using it. We want to make sure Neo4j is a first-class Grails backend so expect more noise in this area in the future.
You can find (some of the) projects using Neo4j on the Neo4j In The Wild page. From the front page of the Neo4j wiki you'll find even more language bindings, tutorials and other things that will support you when playing around with Neo4j!
Happy Holidays and Happy Hacking wishes from the Neo4j team!
