Cumulus is an RDF store on cloud-based architectures. Cumulus provides a REST-based API with CRUD operations to manage RDF data. The current version uses Apache Cassandra as storage backend. A previous version is built on Google's AppEngine. Cumulus is licensed under GNU Affero General Public License.

See our paper at the Scalable Semantic Knowledge Base Systems workshop for a detailed description and some preliminary benchmark results.
