V1: A Visual Query Language for Property Graphs
share
V1 is a declarative visual query language for schema-based property graphs. V1 supports property graphs with mixed (both directed and undirected) edges and half-edges, with enumerated, multivalued and composite properties, and with empty property values. V1 supports temporal data types, operators, and functions, and can be extended to support additional data types, operators, and functions (one spatiotemporal model is presented). V1 is generic, concise, has rich expressive power, and is highly receptive and productive.
