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.
