public class AssetCatalog
extends OCFRESTClient
implements AssetCatalogInterface

The Asset Catalog Open Metadata Access Service (OMAS) provides an interface to search for assets including data stores, event feeds, APIs and data sets, related assets and relationships. Also, it can return the connection details for the asset metadata. The Asset Catalog OMAS includes:

• Client-side provides language-specific client packages to make it easier for data tools and applications to call the interface.
• OMAS Server calls to retrieve assets and information related to the assets.
