"Gremlin is a graph traversal language. The documentation herein will provide all the information necessary to understand how to use Gremlin for graph query, analysis, and manipulation. Gremlin works over those graph databases/frameworks that implement the Blueprints property graph data model. For example: TinkerGraph, Neo4j, OrientDB, DEX, Rexster, and Sail RDF Stores. 1 Please join the Gremlin users group at http://groups.google.com/group/gremlin-users for all TinkerPop related discussions. Finally, if you are a Gremlin user, please add to the Gremlin in the Wild wiki page with your specific Gremlin uses cases."

Besides being able to query and manipulate the underlying data management system with Blueprints, a GraphML reader and writer package is provided with Blueprints for streaming XML graph representations into and out of the underlying graph framework. The GraphML package uses StAX to process a GraphML graph. This section discusses the use of the GraphML library for reading and writing XML-encoded graphs.

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

"The past year I've been learning a lot of Scala and I'm currently working on a new project using Scala. I use LiquiBase, which is a database-independent library for tracking, managing and applying database changes. I'm also using the simple-build-tool (SBT) for my project. So I've put together a little SBT plug-in for running LiquiBase maintenance commands (update, rollback, …) from within SBT. For example, whenever I want to apply new database changes with LiquiBase I can now simply run sbt liquibase-update which sets up a new instance of LiquiBase and executes the LiquiBase update command which migrates my database to the latest version. At the moment the plug-in supports the following commands: liquibase-update, liquibase-drop, liquibase-tag, liquibase-rollback and liquibase-validate. What are the benefits of using the plug-in and not just the LiquiBase CLI? * no download/install of LiquiBase * classpath handled by SBT * no need to provide a big list of parameters or writing shell scripts The plug-in is called liquibase-sbt-plugin and you can find it here on GitHub. Feel free to use it or fork it and suggest changes. I'm still relatively new to Scala and especially SBT so any remarks are very welcome."

Last weekend while pondering the question "Is Scala ready for the enterprise?" I decided to write a simple Java EE 6 app entirely in Scala, without using any Java. I had three main reasons for doing this: one was just to see how easy/difficult it would be to write everything in Scala (it was easy).  Another was to document the process for others journeying down the same road (the entire project is on github).  Finally, I wanted to identify advantages of using Scala instead of Java that are specific to Java EE apps (I found several). Background The specific app I created was an adaptation of the Books example from Chapter 10 of Beginning Java™ EE 6 Platform with GlassFish™ 3. It's a simple web app that displays a list of books in a database and lets you add new books. Although it's a pretty trivial app, it does touch on several important Java EE 6 technologies: JPA 2.0, EJB 3.1 and JSF 2.0.
