    Abstract: Various techniques are described for managing license rights for a variety of digital content. One technique involves initiating a request for a specific content package. The content package includes a unique content package identifier that can be linked with a license offer that also has a unique identifier. A determination is made as to whether the specific content package is available locally, and if not, the specific content package is downloaded. A use license can be obtained for digital content contained within the specific content package. One or more use-license parameters can be determined based on the use license obtained for the digital content. Finally, use of the digital content is enabled in accord with the license parameters that were thus determined.
