Metadata Discovery

Metadata discovery is an automated process that extracts metadata about an asset. This metadata may be:

Some metadata discovery may occur when the asset is first cataloged. For example, the schema of an asset may be stored through the Data Platform OMAS API. This schema may have been automatically extracted by a metadata extractor connector hosted in Egeria’s Data Platform Server which then calls the Data Platform OMAS to store the metadata.

Egeria also supports more advanced metadata discovery.

The Open Discovery Framework (ODF) has open APIs that define how automated discovery services can be managed and interact with an open metadata repository. The metadata repository interfaces provide the metadata discovery service with:

This metadata repository interface for metadata discovery tools is implemented by the Discovery Engine OMAS. Egeria is also able to host automated metadata discovery services that implement the ODF interfaces in its Discovery Server.
