### Validation

Graph Node implements [specification-based](https://spec.graphql.org/October2021/#sec-Validation) validation of the GraphQL queries it receives using [graphql-tools-rs](https://github.com/dotansimha/graphql-tools-rs#validation-rules), which is based on the [graphql-js reference implementation](https://github.com/graphql/graphql-js/tree/main/src/validation). Queries which fail a validation rule do so with a standard error - visit the [GraphQL spec](https://spec.graphql.org/October2021/#sec-Validation) to learn more.

## Schema

The schema of your data source--that is, the entity types, values, and relationships that are available to query--are defined through the [GraphQL Interface Definition Langauge (IDL)](https://facebook.github.io/graphql/draft/#sec-Type-System).
