CumulusRDF is an open source RDF store, designed for write-intensive applications. It is built on top of Apache Cassandra and fully supports high scalable storage of RDF triples and quads. CumulusRDF provides different interfaces to perform data manipulation operations (load, dump remove, and query). The query language supported by CumulusRDF is SPARQL. CumulusRDF is able to execute queries composed of Basic Graph Patterns (BGPs), i.e., the WHERE clause only contains sequence of triple patterns. CumulusRDF can be deployed as a Web application, using an Apache Tomcat server. It offers a SPARQL endpoint, which can handle query requests specified using the SPARQL protocol. CumulusRDF also has a WEB GUI, that provides summary reports about data statistics and performance of the triple store. Through the Web GUI, user are allowed to upload data and query the triple store.
