Blueprints is a property graph model interface API with provided implementations. Databases that implement the Blueprints interfaces automatically support Blueprints-enabled applications.

Tinkerpop: An Open Source Graph Computing Framework

Blueprints

Blueprints is a collection of interfaces, implementations, ouplementations, and test suites for the property graph data model. Blueprints is analogous to the JDBC, but for graph databases. As such, it provides a common set of interfaces to allow developers to plug-and-play their graph database backend. Moreover, software written atop Blueprints works over all Blueprints-enabled graph databases. Within the TinkerPop software stack, Blueprints serves as the foundational technology for:

  • Pipes: A lazy, data flow framework
  • Gremlin: A graph traversal language
  • Frames: An object-to-graph mapper
  • Furnace: A graph algorithms package
  • Rexster: A graph server

Please join the Gremlin users group at http://groups.google.com/group/gremlin-users for all TinkerPop related discussions.
