ANN: First release of CumulusRDF

[I already sent this mail some days ago, but it got lost somewhere, apologies if you receive multiple copies]

Dear all,

we are happy to announce the first public release of CumulusRDF, a Linked Data server that uses Apache Cassandra [1] as a cloud-based storage backend. CumulusRDF provides a simple HTTP interface [2] to manage RDF data stored in an Apache Cassandra cluster. 

Features
* By way of Apache Cassandra, CumulusRDF provides distributed, fault-tolerant and elastic RDF storage
* Supports Linked Data and triple pattern lookups
* Proxy mode: CumulusRDF can act as a proxy server [3] for other Linked Data applications, allowing to deploy any RDF dataset as Linked Data

This is a first beta release that is still somewhat rough around the edges, but the basic functionality works well. The HTTP interface is work-in-progress. Eventually, we plan to extend the storage model to support quads.

CumulusRDF is available from http://code.google.com/p/cumulusrdf/

See http://code.google.com/p/cumulusrdf/wiki/GettingStarted to get started using CumulusRDF.

There is also a paper [4] on CumulusRDF that I presented at the Scalable Semantic Knowledge Base Systems (SSWS) workshop at ISWC last week.

Cheers,
Andreas Harth and Günter Ladwig
