README.md

CumulusRDF (see Wikipedia[1] for details on "Cumulus") is an RDF store on a cloud-based architecture. CumulusRDF provides a REST-based API with CRUD operations to manage RDF data. The current version uses Apache Cassandra as storage backend.

To use CumulusRDF for your project, see the GettingStarted wiki page!

Features

  • By means of Apache Cassandra [2] CumulusRDF offers a highly scalable RDF store for write-intensive applications
  • CumulusRDF acts as a Linked Data server
  • It allows for fast and lightweight evaluation of triple pattern queries
  • It has full support for triple and quad storage
  • CumulusRDF comprises a SesameSail [3] implementation, see CodeExamples wiki page.
  • Further, CumulusRDF contains a SPARQL1.1 endpoint.

Please see our Features as well as our Roadmap wiki page for further information.
