Lumada Data Catalog modifies discovered resource properties to add user-defined metadata to the resource. This metadata holds business value or communicates the data quality of the resource.
There are two types of properties:
- Default resource properties
- Custom resource properties
Default properties are the resource metadata properties that Lumada Data Catalog discovers during the format discovery process. Data Catalog uses standard properties as the default, giving you general information about the resource based on metadata standards.
After making any changes in the default properties, make sure you save and rerun the schema discovery and profile discovery jobs.
User-defined metadata contributes to business value. While you can only define custom properties if you have an Admin role, you can edit or view these properties with other user roles based on policies set by the administrator.
You can access Custom properties for a resource by navigating to thetab for the resource.
Custom properties that are visible but are not available for editing to a role appear grayed out. Typically, the text that appears below the property field describes how the property is to be used or the values it can take. Contact your Administrator for more details.
Custom properties also appear as new facets in the search, so you can use custom properties to perform more complex queries based on your requirements.
