In Pentaho Data Catalog, you can create custom properties that collect additional metadata about resources specific to their business environment or engagement. For example, you can define a custom property to include a business username for a data resource. Alternatively, you could define a property that includes values that are used by system-level processes.
Note: Custom properties apply only to data resources.
To add custom data resource properties, navigate to Data Canvas, select the resource and then in the content pane, click Add Property. While the Properties page lists a variety of properties, users can only manage custom properties using the Add Property option.
