All Known Implementing Classes:

AssetCatalog

public interface AssetCatalogInterface

The Asset Catalog Open Metadata Access Service (OMAS) provides services to search for data assets including data stores, event feeds, APIs and data sets. The search will locate assets based on the content of the Asset metadata itself and the metadata that links to it. This includes:

• Glossary terms
• Schema elements
• Classifications
