0615 Schema Extraction

One of the simplest discovery processes for relational data is to extract the schema details from the asset through the JDBC connector getMetadata() API. Other connectors or data sources may also provide APIs for schema extraction. The schema is first added as an annotation that links together the data fields found.

This is then either matched with an existing schema or a new schema is created (see Area 5). This may be completely automated, or with stewards assistance.
