Description

Description Gremlin has support in many graph databases, a syntax that is a little more JavaScript-y. I suggest making LinkedQL semi-compatible with Gremlin for features unrelated to property graphs.

Research direction
Start by understanding Gremlin's syntax and how it compares to LinkedQL. Explore Cayley's query engine in the 'query' directory, particularly the LinkedQL implementation. Look at existing issues and discussions (e.g., comments on this issue) for specific features to align. Consider designing a compatibility layer that translates Gremlin like syntax to LinkedQL queries without modifying property graph specifics.
