About the primary, mandatory, and optional fields

The primary fields are the identifier fields. The primary fields are used to identify the asset type exclusively.

The mandatory fields are the fields that are required for data collection and evaluation. Without the presence of the mandatory fields, the asset is not imported into the asset system.

The optional fields are the fields that are not required for asset import, data collection, or evaluation. The new fields that you can add to the custom asset type are optional fields. They have no reference to the entity schema.
