Gremlin: All content tagged as Gremlin in NoSQL databases and polyglot persistence
A slide deck by Pierre De Wilde with a short theoretical intro to property graphs and graph databases and an extensive set of examples of manipulating and traversing graph data with Gremlin. Good reference material.
A new version of InfiniteGraph, the graph database from Objectivity, was announced today. This release features:
- a plugin framework: Two kinds of plugins are supported. A navigator plugin bundles components that assist in navigation queries, such as result qualifiers, path qualifiers, and guides. The Formatter plugin formats and outputs results of graph queries.
- enhanced IG Visualizer: The advanced Visualizer is now tightly integrated with InfiniteGraph’s Plugin Framework allowing indexing queries for edges, the Formatter plugin framework export GraphML and JSON (built-in) or other user defined plugin formats.
- support for Tinkerpop Blueprints and Gremlin: InfiniteGraph provides a clean integration with Blueprints that is well suited for applications that want to traverse and query graph databases using Gremlin
A bit more details can be found in the InfiniteGraph 2.1 release notes.

Recently Max de Marzi has published sort of a getting started with Neo4j on Heroku guide. Here is how Max described it:
It takes a lot less effort to build a website these days than it used to. All it takes is a clever dwarf standing on the shoulders of the right giants. In a series of blog posts, I walk you through creating a movie recommendation website using Neo4j, Heroku, themoviedb.org, Processing.js, GroupLens, Marko Rodriguez and Michael Aufreiter. Free database, free hosting, free movie posters, free visualization, free dataset, free recommendation algorithm, just need to add a little code to bring them all together and BYOP (bring your own popcorn).
This will not get you a Netflix or Amazon like recommendation engine, but using a similar approach could definitely tell if Muhammad Ali is truly the greatest.

A nice intro to Gremlin, the Groovy-based graph traversal language supporting Neo4j, OrientDB, DEX, RDF Sail, TinkerGraph, and ReXster:
