Abstract

Techniques enable building a collection of data that defines an asset, with the data possibly having differing data types. These techniques are then capable of assigning arbitrary policy to that asset, regardless of which data types are present within the asset. In addition, these techniques enable packaging of this first asset with one or more additional assets in a self-contained envelope. Each asset within the envelope may similarly include data of differing data types. Furthermore, each of these assets may be assigned a policy that may be different than the policy assigned to the first asset. This envelope, or a collection of envelopes, may then be provided to a content-consuming device to consume the assets in accordance with each asset's specified policy.
