After you run a catalog source with lineage discovery enabled, you can view the list of related catalog sources with the endpoint object recommendations. You can then accept or reject them.
When you run a catalog source with the lineage discovery capability, CLAIRE identifies matching objects in connected catalog sources and calculates the percentage of matched and unmatched objects. The higher the percentage of matched objects, the more accurate the lineage that you view in Data Governance and Catalog. You can accept or reject each CLAIRE recommendation individually. Alternatively, you can select multiple recommendations to accept or reject them in bulk. When you accept a CLAIRE recommendation, Metadata Command Center creates links between the endpoint objects in the connected catalog sources.
If you accept a CLAIRE recommendation, the selected catalog source is accepted, and future recommendations are also accepted. If you initially reject CLAIRE recommendations and later accept them, the status changes from rejected to accepted. When you accept a CLAIRE recommendation, the connection assignment job starts. You can check the status of the job on the Monitor page.
After you curate the CLAIRE recommendations, you can view the complete lineage in Data Governance and Catalog.
Note: Due to change in metadata and connection assignment of accepted catalog sources, CLAIRE recommendations can become outdated over time. Run the catalog source job again with the lineage discovery capability to refresh the recommendations.
Accept or reject CLAIRE recommendations

After you accept the CLAIRE recommendation, the connection assignment job starts. You can check the status of the job on the Monitor page. When the job completes, the connection is successfully assigned and Metadata Command Center creates links between the recommended objects in the connected catalog sources. The higher the percentage of matched objects, the more accurate the lineage that you view in Data Governance and Catalog.
Resolve conflicts
You might notice conflicts between connections in CLAIRE recommendations. If there are conflicts, resolve and accept the CLAIRE recommendations.
Conflicts between connections can occur in the following scenarios:
•Duplicate metadata across catalog sources.
•Duplicate catalog source configurations.
•Same metadata in the catalog from production and other non-production environments.
•High percentage of matches in multiple catalog sources for the same connection.
Note: When you configure a catalog source, add filters for lineage discovery to avoid duplicate recommendation conflicts.
