The document covers a presentation by Jason Plurad on graph computing using Apache TinkerPop, an open-source graph framework featuring the Gremlin graph traversal language. It discusses various graph databases, integrations, and provides examples of Gremlin queries and graph operations. The document also highlights contributions and resources for developers interested in graph technology.

Gremlin Language Drivers

11. § Elevate Gremlin to a top-level citizen in the programming language of choice
§ GLV can work with any modern language
– Function composition
– Function nesting
§ Java and Groovy (native)
§ Python is the first non-JVM GLV
§ Others are coming soon (JavaScript, C#, Go)
§ SPARQL-Gremlin and SQL-Gremlin
