Metadata Patterns

Metadata Patterns

A metadata pattern is a regular expression that identifies column names in a source. A metadata pattern can contain multiple metadata expressions.
A metadata expression can be a column name or part of a column name. For example, if you configure
.*Name*
as a metadata expression, column names such as Name, Employee_Name, and Organization_Name in the source appear in the search result.
A column name that matches any metadata expression in the pattern appears in the search results.
A Social Security number might have different column names. The following regular expressions are metadata expression to find Social Security numbers by column name:
.*SSN* .*SOCIAL* .*SECURITY*
