Hey HN, I'm Dominik Tomaszuk and I want to share my book introducing Graph Query Language (GQL) that is the new ISO standard for query language for property graphs (ISO/IEC 39075).

The book covers data model, syntax, queries, and data manipulation. You can find a lot of practical examples there.

The book is freely available online at https://gql.fyi/

I hope the book will be useful to developers, researchers, and anyone interested in graph databases.
