Subject [ANN] Jena 2.13.0, Elephas and Fuseki2
Date Fri, 13 Mar 2015 13:22:26 GMT
We are pleased to announce the release of Apache Jena 2.13.0.  This is a 
major release with several new features.

* Elephas, a framework for working with RDF on Apache Hadoop

* Fuseki2, with security and a new UI for server use and administration

* An OSGi bundle

== Elephas

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.

== Fuseki2

The release of Apache Jena Fuseki2 includes server security and an all 
new server admin UI.  It is available both as a standalone server, and 
packaged as a WAR file.

The security is provided by Apache Shiro.  This can be configured to 
meet specific deployment needs.

The new UI provides administration of a running server, including 
managing datasets. At the moment, it provides the abilities to create 
datasets, upload data, query the data and to backup the database on a 
live server.

This interface is new and we are seeking contribution and feedback to 
help shape it's evolution.

This incorporates component and contributions from YASR (with thanks to Laurens Rietveld)

Fuseki v1 continues to be available.  To ease transition, the Fuseki v2 
standalone server can be run in the same way as Fuseki1 for existing 
configurations. The Fuseki1 and Fuseki2 UIs are not compatible.

== OSGi bundle

Each Apache Jena release now produces an OSGi bundle.

Thanks to Stian Soiland-Reyes for contributing this and working with 
early users.
