Atlan GraphQL API
Atlan exposes a tenant-scoped GraphQL API that provides flexible querying of the platform's knowledge graph — the unified metadata layer spanning 80+ data sources. Through GraphQL, clients can traverse relationships between assets (tables, columns, schemas, databases, dashboards, pipelines) and their associated metadata including Atlan Tags (classifications), business glossary terms, data lineage connections, custom metadata, and governance artifacts such as Personas and Purposes. The schema follows the Apache Atlas entity model extended with Atlan-specific types, meaning every asset is a subtype of the root `Asset` interface, which itself extends `Referenceable`.
