Core Model

Definitions of Flow, Task, DAG, and how they relate.

Metadata dimensions

Every flow carries three metadata fields that govern organization, identification, and filtering:

  • Namespace: hierarchical grouping string (e.g. data/ingestion)
  • Version: immutable identifier per flow registration (e.g. 1.0.0 or latest)
  • Tags: arbitrary key-value labels (e.g. {"team": "data-eng", "env": "prod"})

See Namespaces, Versioning & Tags for full details on derivation rules, storage layout, and conventions.
