Description

This is a set of exploratory features in which the ANTLR grammar Gremlin.g4 will be supplemented by, and possibly generated from, a higher-level specification in YAML. Generalizing the grammar in this way will potentially allow grammars for additional Gremlin language variants to be generated, and the common specification (for traversals as well as the core property graph data model) can also be used for generating structure and process APIs in multiple languages in parallel. See TinkerPop 2020 for a discussion of related open problems, and How to Build a Dragon (Part 3) for a demonstration of some of the anticipated features.
