Hi Laurent, Marko, Josh and me are developing Gremlin. It aims at providing a capable graph tinkering interface that can be used to prototype and test graphy problems like recommendation algos, PageRank, Bayesian stuff while being able to plug in different "graphy" backends like raw graphs like Neo4j, RDF, LinkedData, or less obvious choices like MongoDB- or maybe even relational datasets. Gremlin lets you treat all these datasets in a common way and even intersect them within the same expression.
These things would otherwise require implementation-specific programming as SPARQL, MQL, GQL etc are not able to express real graphy algos. Also programmatic access is not that easy to tinker with for domain experts, researchers and ad-hoc-query stakeholders like people interested in reporting, business intelligence etc. So, Gremlin wants to promote graph thinking. It is 0.1 ALPHA, and you should build it from source, but we have a number of tests and it actually is working. Last week I imported the small BillionTripleChallenge dataset (10M Triples) into Neo4j and ran a FOAF algo on it via Gremlin, https://svn.neo4j.org/laboratory/users/peter/batchtest/ , and ran snippets.grml over it. Gremlin is of course not as fast as codign Neo4j Traversers, but it does a decent job at fast getting you good results. Now, there are a number of interesting things missing, like a WebUI, a good return (JSON) format etc etc, but if you wanna tinker, let us know your verdict!
