sones the producer of a (until now) commercial closed source graph database has released recently its first open source version of GraphDB. This new version, GraphDB 1.1, is available under both a GNU AGPLv3 open source license and a proprietary commercial license.
GraphDB source code is already available on ☞ GitHub. Even if developed in C#, the GitHub project page contains clear instructions on how to built sones GraphDB for Linux and MacOS (requires Mono).
You can get a feel of how using sones GraphDB compares to other graph databases by looking at this example code implemented with sones GraphDB, InfoGrid, Neo4j, and Filament. And before downloading sones GraphDB 1.1, you should also check this useful GQL cheatsheet (the sones GraphDB query langauge) in PDF format:
Last, but not least, sones guys have started to publish ☞ a tutorial in the form of a series of articles that puts CrunchBase data to work in a graph database environment.
Time to hit the ☞ GitHub page and get sones GraphDB while it’s hot! Good move sones!
Update: In case you are wondering why having sones GraphDB open source version is not just cool, but really useful, here is a possible answer.
Until now, if you wanted to use a graph database, you only had one of these options
- use the Java VM as most of the other graph databases are developed in Java and supposed to run embedded
- use the Neo4j RESTful service (you can read more about it in our coverage of the Neo4j 1.0 release)
- use Twitter’s FlockDB, keeping in mind though that it is not a complete graph database
Now, sones GraphDB not only opens the doors to graph databases to .NET developers, but it also features a REST interface like Neo4j making it accessible to more programming environments.
