Discover your data through keyword search, associated data (e.g., frequently joined tables, lineage), and complex queries. OpenMetadata supports discovery across tables, topics, dashboards, pipelines, and a their components (e.g., columns, charts) through metadata annotations and data profiling. OpenMetadata includes support for discovery based on complex data types such as arrays and structs.
Discover assets through frequently joined tables and columns as measured by the data profiler. You can also discover assets through relationships based on data lineage.
Tier tags enable you to annotate assets with their importance relative to other assets. The Explore UI enables you to filter assets based on importance. 
Use ownership metadata to determine the primary points of contact for any assets of interest in order to get help with any questions you might have.
Enable the data profiler through metadata ingestion to capture the profile of tables over a period of time. This will help your users check for null values in non-null columns, for duplicates in a unique column, etc. Understand column data distributions through min, max, mean.
See the [Connectors](../install/metadata-ingestion/connectors/) documentation for information on available connectors and how to integrate your services with OpenMetadata.
