Apache Jena is framework for building linked data and semantic web applications. The team is pleased to announce new functionality in Jena 2.13.0 to support working with RDF data on Apache Hadoop. Apache Jena Elephas is a new set of modules which provide the basic building blocks necessary to write RDF producing and consuming Hadoop 2.x applications. It provides a Common library which contains Hadoop Writable implementations for the basic RDF primitives (Node, Triples and Quads), an IO library which contains input and output format support for all RDF serialisations Jena supports and a Map/Reduce library which contains some basic Mapper and Reducer implementations for manipulating RDF. There is also a demo application that shows how to use these libraries to compute some basic statistics across arbitrary RDF data. These libraries have been under development for some time but not yet widely deployed in production environments, we would appreciate any feedback on bugs, missing features and documentation improvements. http://jena.apache.org/documentation/hadoop/ For a high level overview of these libraries you may want to take a look at the following presentation I gave recently at the London Semantic Web Meetup: http://www.slideshare.net/RobVesse/apache-jena-elephas-and-friends Regards, Rob Vesse On behalf of the Apache Jena team
