hydra-pg: Hydra's property-graph (TinkerPop/Gremlin) model and coder support

[ apache, data, library ] [ Propose Tags ] [ Report a vulnerability ]

Hydra is an implementation of the LambdaGraph data model, which takes advantage of an isomorphism between labeled hypergraphs and typed lambda calculus: in Hydra, "graphs are programs, and programs are graphs". Property graph support for Hydra
