Export Lineage Repository

To support advanced lineage use cases, such as analysis, backup, and migration, you can export lineage repositories in CSV format.

Why export lineage repositories?

Exporting the repository provides a complete snapshot of all lineage assets, including catalog items, relationships, and metadata. This capability is especially useful for:

Backup and restore

You can export the current lineage repository and store it externally for backup purposes. The exported file can be later reimported to restore the original state.

Migration between environments

Exporting allows you to move lineage data between environments (for example, from dev to staging, staging to prod). Export the archive from one environment and import it to a different instance.

Offline analysis and reporting

You might wish to analyze lineage structure outside the platform, using processing or scripting tools to detect patterns, gaps, or inconsistencies.

How exporting a lineage repository works

You can export the lineage repository by selecting Export CSV in the upper-right corner of the Lineage Assets screen. This downloads a ZIP archive containing all assets in CSV format.

The archive includes:

  • All catalog items and their metadata.

  • All dataflows and dependencies.

  • Metadata required for reimport.

The archive can be directly used to import lineage back to Ataccama ONE. This allows for a smooth round-trip of exporting and reimporting lineage data.

The exported lineage files use the Ataccama Lineage format, as described in Ataccama Lineage Format.

How to export a lineage repository

To export the full lineage repository:

  1. Navigate to Knowledge Catalog > Lineage Assets.

  2. Select Export CSV to start the export. The output ZIP file is saved to your local Downloads folder.

    Export CSV button

You can later reimport the downloaded ZIP file into Ataccama ONE to restore or migrate the repository.

Export not available

In some cases, such as when no lineage assets are available, the Export CSV option is grayed out and cannot be used.

Export CSV is not available

This means that the current repository state cannot be exported. To reestablish lineage content, first import your lineage metadata.
