Asset metadata

Organizing assets with tags and metadata

Assets feature prominently in the Dagster UI. Attaching information to assets allows you to understand where they're stored, what they contain, and how they should be organized.

Tags

Tags are the primary way to organize assets in Dagster. You can attach several tags to an asset when it's defined, and they will appear in the UI. You can also use tags to search and filter for assets in the Asset catalog in Dagster+. They're structured as key-value pairs of strings.

Kind tags for categorizing assets

Use kind tags to easily categorize assets within you Dagster project.

Asset observations

Dagster provides functionality to record metadata about assets.
