Curation in the Analyst tool
Curation is the process of validating and managing discovered metadata of a data source so that the metadata is fit for use and reporting. When you curate metadata in the Analyst tool, you can approve, reject, and reset the inferred data types or data domains in profile results.
You can approve one data type and one data domain for a column. You can hide the rejected data types or data domains for a column. After you approve or reject an inferred data type or data domain, you can reset the data type or data domain to restore the inferred status.
