There are two main Java APIs in Gremlin: 1. using Gremlin through Java 2. getting a graph view of various data management systems 1. Using Gremlin through Java There is currently no documentation on using Gremlin through Java -- all the documentation is through the Gremlin console. This is my next step in the documentation. However, if you have the patients to look at classes, see GremlinEvaluator.java. Finally, all the commands you would issue through the console can be issued through GremlinEvaluator.evaluate(String line). 2. Getting a Graph View of Various Data Management Systems There is something in the Gremlin distribution called The General Graph Model (GGM). You can learn about it here: http://wiki.github.com/tinkerpop/gremlin/the-general-graph-model The model was created to create an abstraction layer between Gremlin and the underlying data management system that Gremlin is manipulating (e.g. Neo4j, SAIL RDF stores, MongoDB, etc.). The benefit of this is that as long as you can implement the GGM for a data management system, then Gremlin will work over it. However, just implementing interfaces is not enough, you need to ensure that the semantics of implementation are correct. To ensure this, GGM comes with a test suite to verify an implementation. You can learn about that here: http://wiki.github.com/tinkerpop/gremlin/the-general-graph-model-test-suite In summary, GGM is trying to be to graphs what JDBC is to SQL databases and SAIL is to RDF stores. A future plan is to take GGM out of the Gremlin package and make it its own distribution so that data management system developers will be incentivized to provided a GGM implementation of their system. Thus, GGM is generally useful beyond just Gremlin and make Gremlin generally available for many data management systems.
