Abstract

In a system for managing and updating metadata associated with an asset, an asset provider can associate the asset with metadata. If the asset provider wants to distribute the asset to one or more distribution endpoints, the asset provider can send an asset bundle comprising the metadata and the asset to the distribution endpoints. In the event the asset provider modifies or updates the metadata associated with the asset, the asset provider can identify which distribution endpoints are to receive the updated metadata. After identifying which distribution endpoints are to receive the updated metadata, the asset provider can send the updated metadata without manual intervention to each of these distribution endpoints. Alternatively, the metadata may be stored by a metadata administrator, and the metadata may be sent to distribution endpoints upon the metadata administrator receiving a request for the metadata from the distribution endpoints.
