In their own words
Dydra
Dydra is a cloud graph database for highly connected data, including social networks. It stores information as a property graph and supports SPARQL 1.1 queries and updates through a standard endpoint for each repository. Repositories import RDFa, RDF/JSON, N-Quads, N-Triples, RDF/XML, TriG and Turtle, and export N-Triples, Turtle and RDF/XML. Dydra also provides a standard REST API and a Ruby client gem that can operate as a command-line interface. The service says it manages versioning, disaster recovery and performance for the data store. Described applications include social networking, movie relationships and transaction logs. A free Basic use plan has limited resources: public evaluation accounts allow five queries per second and repositories should remain at or below one million statements. Federation is disabled for public accounts, and the default graph is fixed to the repository default. Customers retain data ownership and may delete data. Dydra is headquartered in Berlin, Germany.
