What is Dydra?• Dydra is a cloud-based RDF database and
SPARQL service, delivered as a service (DaaS).
• In development since 2009, incorporated in 2011. Technology team based in Berlin.
• Provides free hosting for ontologies and small Linked Data datasets (“GitHub for RDF data”), each repository including a SPARQL endpoint.
• Commercial arrangements available for managed turnkey hosting of larger datasets on dedicated hardware in the cloud (or on-site), with SLAs.

Features of Dydra
• Standards support—SPARQL 1.1 Query, Update, Federated Query, Graph Store HTTP Protocol.
<http://blog.dydra.com/>
• First-class revision history—query access to revisions, temporal federation across revisions.
• SPARQL extensions—implicit reification, collation, temporal operators, provenance operators, etc.
• Materialized views and strong cache identifiers—efficient remote access to named result sets.
• All major RDF serialization formats, and others: JSON-LD, Turtle, RDF/XML, RDF/JSON, N-Triples/ N-Quads, TriX, Pajek, Graphviz, etc.
BioHackathon Goals
• Provide instant hosted RDF repositories and SPARQL endpoints for hackathon groups, on demand.
• Learn more about specific requirements in bioinformatics that RDF store developers like myself should accommodate and facilitate—e.g., revisioning, provenance, cached federation?
• Make the case for teachers and publishers to consider uploading their data to Dydra—getting a SPARQL endpoint and all RDF export formats.
• Meet RDF.rb users and learn how the RDF.rb development team can help support usage.
