Announcing the availability of the SHER ontology reasoning engine

We are pleased to announce the release of SHER, a highly scalable  
ontology reasoning engine for OWL ontologies.  SHER is available on  
http://www.alphaworks.ibm.com/tech/sher for a download.  SHER is free  
for academic use, and includes the source code.  SHER is built on  
Pellet, and scales to large instance datasets stored in relational  
datasets (upto 300 million RDF assertions). SHER answers semantic  
queries issued in a SPARQL format, and relies on DB2 (a free version  
of DB2 is available for download).
