These certifications are sourced from Looker. Once the Looker crawler has run successfully and detected that an asset was deleted, Atlan will attached a Deprecated certificate to the asset because it no longer exists at source. For example:
- If tiles are deleted, the API response generated is titled Look Deleted. In this case, Atlan will add the deprecated certificate.
- If Atlan crawls any models that do not have a project associated with them (indicated by a missing
project_namekey in the model API response), Atlan adds a deprecated certificate to the asset.
