Detailed Description

Represents a list of portal items.

A PortalItem is a unit of content in the Portal. This type is populated by starting an operation to retrieve content and then can be accessed after the operation is complete. For example, the list of items can be retrieved by: querying the portal (such as with PortalQueryParametersForItems) or by fetching the featuredItems or by fetching the items belonging to a user.

The model returns data for the following roles:
