I think on a general level, the priority goes like this:
- Official GraphQL spec.
- Gremlin.
- Cypher? / GQL? / SPARQL? – we’ll have to decide based on the adoption. Cypher, while popular, is still a niche language, and not a standard by any means. Neo4j is pushing for GQL, so by the time we support Gremlin, hopefully it is clear where do these cards fall. https://gql.today/
