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 by reference 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.)
- Security model
- Client model and session model?
By referencing the existing specifications in the SQL standard, GQL eliminates the need to redo a lot of detailed foundational work.
- Capabilities needed by both SQL/PGQ (Property Graph Queries in SQL) and the GQL standard
- Originally integrated into SQL/PGQ:2020
- Split into a separate part as GQL project progresses, referenced by both GQL and SQL/PGQ
- Graph Pattern Matching
- Etc...
- GQL Specific Capabilities
- Graph-only data types
- Vertex
- Edge
- Path
- Graph operations not included in SQL:/PGQ:2020
- Graph analog of SQL/Schemata
- Graph-only data types
Possible Timeline for a GQL Standard
Possible Timeline for a GQL Standard
The following is a speculative, optimistic timeline for the progression of a formal Graph Query Language Standard
- 2019-01 – Initial outline of Working Draft to SC32WG3
- 2019-03 – W3C Workshop on Graph Data
- 2019-06 – SC32 WG3 New Work Item Proposal
- 2019-09 – 2020-02 – Two WG3 Working Group Meeting
- 2020-03 – CD Ballot starts
- 2020-06 – CD Ballot comment resolution
- 2020-07 – DIS (Draft International Standard) Ballot
- 2021-02 – Comment resolution
- 2021-05 – FDIS (Final DIS) Ballot
- 2021-08 – International Standard
This timeline depends on work that has not yet been done.
