Any protected resource that imports from an IMS Common Cartridge package displays a 
Protected icon beside it. When users first try to access a protected resource, they are prompted for an access code, which is distributed by the package creator. Entering the access code and accepting the license agreement initiates the electronic authorization with the package creator’s authorization web service and unlocks the resource for the user.
The user is not prompted to enter their access code when accessing additional protected content from the package until the authorization period ends. The length of the authorization period is determined by the package creator and changes from one package to another. If a course contains protected resources from multiple packages, users are typically prompted for authorization only once per protected package.
Protected resources can be copied between courses, but cannot be exported from iLearn Learning Environment.
