Abstract

Systems and methods are described for performing policy-managed, peer-to-peer service orchestration in a manner that supports the formation of self-organizing service networks that enable rich media experiences. In one embodiment, services are distributed across peer-to-peer communicating nodes, and each node provides message routing and orchestration using a message pump and workflow collator. Distributed policy management of service interfaces helps to provide trust and security, supporting commercial exchange of value. Peer-to-peer messaging and workflow collation allow services to be dynamically created from a heterogeneous set of primitive services. The shared resources are services of many different types, using different service interface bindings beyond those typically supported in a web service deployments built on UDDI, SOAP, and WSDL. In a preferred embodiment, a media services framework is provided that enables nodes to find one another, interact, exchange value, and cooperate across tiers of networks from WANs to PANs.

Claims

1. A method performed by a computer system, the computer system comprising a computer-readable medium storing software for processing content encoded in a first digital rights management format, the method comprising:

performing a service discovery process to locate a service that is capable of enabling the computer system to access a piece of content encoded in a second digital rights management format;

sending a request for the piece of content to a first service provider, the first service provider providing a service that is capable of enabling the computer system to access the piece of content, the first service provider having been identified by the step of performing a service discovery process; and

receiving the piece of content in a format that can be processed by the computer system.

2. The method of claim 1, further comprising:

receiving a token from the first service provider, the token being configured to enable the computer system to download the piece of content in a format that can be processed by the computer system.

3. The method of claim 1, in which the computer system further comprises a workflow collator, the method further comprising using the workflow collator to coordinate performance of a plurality of steps, the steps including:

obtaining permission from a second service provider to receive a piece of software for processing content encoded in the second digital rights management format; and

downloading the piece of software from a third service provider.

4. The method of claim 1, further comprising:

obtaining a piece of software for processing content encoded in the second digital rights management format.

5. The method of claim 4, further comprising:

obtaining permission to receive the piece of software for processing content encoded in the second digital rights management format.

6. The method of claim 1, further comprising:

receiving information from the first service provider regarding service bindings for accessing the service that is capable of enabling the computer system to access the piece of content.

7. The method of claim 6, in which the computer system further comprises a service access point for creating the request, the service access point being configured to automatically formulate the request in a manner that adheres to the service bindings for accessing the service.

8. The method of claim 1, further comprising:

negotiating a trusted relationship with the first service provider.

9. The method of claim 8, in which negotiating a trusted relationship with the first service provider includes exchanging trust credentials with the first service provider.

10. A computer system comprising:

a computer-readable medium storing digital rights management software, the digital rights management software being configured to process content encoded in a first digital rights management format;

means for performing a service discovery process to locate a service that is capable of enabling the computer system to access a piece of content encoded in a second digital rights management format;

means for sending a request for the piece of content to a first service provider, the first service provider providing a service that is capable of enabling the computer system to access the piece of content; and

means for receiving the piece of content in a format that can be processed by the computer system.

11. The system of claim 10, further comprising:

means for obtaining a token from the first service provider, the token being configured to enable the computer system to download the piece of content in a format that can be processed by the computer system.
