We are happy to announce the new major release FedX 3.0.

FedX is a framework for efficient federated query processing involving
multiple distributed Linked Data sources. FedX allows to easily setup
on-demand federations by specifying a list of relevant datasets (e.g.
SPARQL endpoints from the LOD cloud) and to query these in an efficient and
transparent way as a virtually combined dataset. Implemented as a Sesame
SAIL, FedX can be used in Java applications or via an easy-to-use command
line interface.

Going beyond the federation support defined in the SPARQL 1.1 federation
extensions, FedX makes it possible to dynamically set up federations over
distributed sources and efficiently execute standard SPARQL queries (i.e.,
queries without federation extensions) transparently over the federation.

New in this version:

* Support for latest SPARQL 1.1 language features
* Monitoring facilities (query log, query plan, JMX monitoring)
* Usability improvements (validation of endpoints, robustness, error
reporting)
* Improvements to optimization techniques (join order rules, bound joins
using VALUES, ...)
* IDs of federation members can be used as aliases in SERVICE
* Upgrade to Sesame 2.7.3
* Documentation
* Various minor Bugfixes

On behalf of the FedX team,
 Andreas
