Maven Central

Blazegraph 2.1.2 is now on Maven Central.    You can also get the Tinkerpop3 API and the new BlazegraphTPFServer.

    <!-- Use if Tinkerpop 2.5 support is needed ; See also Tinkerpop3 below. -->


Blazegraph Tinkerpop3

Tinkerpop3 is here!  Get it from Maven Central.


Blazegraph-Based TDF Server
The Blazegraph-Based TPF Server is a Linked Data Fragment (LDF) server that provides a Triple Pattern Fragment (TPF) interface using the Blazegraph graph database as backend.  It was originally developed by Olaf Hartig and is being released via Blazegraph under the Apache 2 license.   See here to get started.


Everybody loves (and hates) Maven.  Starting with the 2.0.0 release, Blazegraph has been broken into a collection of maven artifacts.    This has enabled us to work on new features like TinkerPop3, which require Java 8 support while keeping the core platform at Java 7 to support users who are still there.   Checkout the Maven Notes on the wiki for full details on the architecture, getting started with development, building snapshots, etc.  If you have a 1.5.3 version checked out in Eclipse, you will want to pay attention to Getting Started with Eclipse and allocate a little extra time for the transition.


2.1.2 provides updates for the Debian Deployer, an RPM Deployer, and a Tarball.  In addition to the blazegraph.war and blazegraph.jar archives.

    I can’t install rpm on Fedora. “addgroup” command in Fedora doesn’t exist, and the script inside rpm fail.
