The GQL project is the culmination of converging initiatives dating back to 2016, particularly a private proposal from Neo4j to other database vendors in July 2016<ref name="Creating standard">{{cite web|url=https://s3.amazonaws.com/artifacts.opencypher.org/website/materials/DM32.2/DM32.2-2018-00144.Creating+an+Open+Industry+Standard+for+a+Declarative+Property+Graph+Query+Language.pdf|title=''Creating an Open Industry Standard for a Declarative Property Graph Query Language''|last1=Green|first1=Alastair|date=July 2016|website=|publisher=opencypher.org|accessdate=November 12, 2019}}</ref>, and a proposal from Oracle technical staff within the ISO/IEC JTC 1 standards process later that year<ref name="Towards NWIP">{{cite web|url=https://s3.amazonaws.com/artifacts.opencypher.org/website/materials/DM32.2/DM32.2-2018-00128r1.Working+towards+a+GQL+NWIP.pdf|title=''Working towards a New Work Item for GQL, to complement SQL PGQ'', ANSI INCITS DM32.2 submission ''DM32.2-2018-00128r1''|last1=Green|first1=Alastair|date=July 2018|website=|publisher=opencypher.org|accessdate=November 12, 2019}}</ref>.

The GQL project is led by Stefan Plantikow (who was the first lead engineer of Neo4j's Cypher for Apache Spark project) and Stephen Cannan (Technical Corrigenda editor of SQL). They are also the editors of the initial early working drafts<ref name="GQL EWD v2.2">{{cite web|url=https://isotc.iso.org/livelink/livelink?func=ll&objId=20836584&objAction=Open|title=''GQL Early Working Draft v2.2''.|last=Eds.

As originally motivated<ref name="Towards NWIP"/>, the GQL project aims to complement the work of creating an implementable normative natural-language specification with supportive community efforts that enable contributions from those who are unable or uninterested in taking part in the formal process of defining a JTC 1 International Standard<ref name="community">{{cite web|url=https://www.gqlstandards.org/|title=''GQL Standard''|accessdate=November 12, 2019}}</ref><ref name="GCU 3">{{cite web|url=https://www.gqlstandards.org/community-updates|title=''GQL Community Updates''|accessdate=November 12, 2019}}</ref>. In July 2019 the Linked Data Benchmark Council (LDBC) agreed to become the umbrella organization for the efforts of community technical working groups. The Existing Languages and the Property Graph Schema working groups formed in late 2018 and early 2019 respectively. A working group to define formal denotational semantics for GQL was proposed at the third GQL Community Update in October 2019<ref name="FSWG">{{cite web|url=https://drive.google.com/open?id=15DAUAORu477FF-DooTH2ol0SZhx2ARtr|title=''Formal Semantics Working Group''|last=Libkin|first=Leonid|accessdate=November 12, 2019}}</ref>.
