This was the fourth virtual meeting for members of the openCypher Implementers Group, with the aim of discussing, agreeing upon or rejecting Cypher language changes proposed via Cypher Improvement Requests (CIRs) and Improvement Proposals (CIPs).

The main focus of this meeting was dedicated to the topic of multiple graphs, with an emphasis on syntax and semantics. Additionally, a proposal was presented for the integration of graph query procedures (written in a graph query language) into SQL.
