What is a GQL Standard?
What is in a Graph Query Language Standard?
The current thought is that the GQL Standard will be two or three parts that include:
Incorporate specifications from SQL/Framework and SQL/Foundation (ISO/IEC JTC1 9075:2016 parts 1 & 2), including:
Some scalar data types
Operations, functions, and predicates for the scalar types
Transaction model (isolation level, COMMIT, ROLLBACK, etc.)
Client model and session model?
Graph Pattern Matching
Identical to Graph Pattern Matching in SQL/PGQ:2023
GQL Specific Capabilities
Graph-only data types
Graph operations not included in SQL:/PGQ:2023
Queries (using GPM)
Graph analog of SQL/Schemata
