The text discusses the development of a JSON-based data model for Neo4j's property graph database. The goal is to provide a standardized way to describe and validate the schema of the database, allowing for better tooling and integrations with other applications. A proof-of-concept plugin has been developed to introspect the database and generate a JSON representation of the schema, which can be used for validation and visualization. The schema is based on a tokenized approach, where nodes and relationships are represented as classes and concrete instances, respectively. The algorithm uses existing Neo4j APIs to retrieve labels and relationship types, and groups them by sorted combinations to create node object instances and relationship instances. The JSON schema can be used to validate the data model and visualize its structure in a graphy visualization tool. The plugin is available for download and can be run within a Neo4j installation or built from source using Java 17. The authors invite feedback on the project, including comments on the JSON schema, data model materialization, introspector algorithm, and utility library.
