is specialized in the Graph Database field. It provides different Open Source projects to work with a GraphDB. The TinkerPop Blueprints
project aims to have a shared set of basic interfaces to abstract the concepts of Graph, Vertex, Edge and Property. This is the closest thing to a standard for Graph DBMSs. Other projects works on top of the Blueprints: Gremlin, Rexster, Pipes and others. TinkerPop and Orient Technologies staff together built the OrientDB implementation of the Blueprints.
