Fundamentals
Description	A multi-model database supporting graphs, key-value pairs, and documents in a unified JSON-based data model, stored in a RocksDB-based engine. Since version 3.12 the server no longer runs graph algorithms itself (the Pregel system was removed); they run in separate Graph Analytics Engines on the Arango platform.	A knowledge graph management system from the University of Oxford that reasons over knowledge graphs in the Vadalog language, built on Warded Datalog+/- to combine full recursion with ontological reasoning at polynomial data complexity. Developed in the VADA research programme and commercialised by Prometheux as Vadalog Parallel.
