Abstract

Associative management of distributed multimedia assets and associated resources using multi-domain agent-based communication between heterogeneous peers is achieved using an Asset/Resource Management (ARM) platform architecture that has an ARM Framework that is used by Asset Management Agents. The ARM Framework includes an ARM Infrastructure which is a system of protocols and libraries from which communities of agents that are grouped in logical Agent Domains are built. The agents communicate via the KQML language embedded within TCP/IP messages, advertise their capabilities and cooperate together to perform meaningful work. An XML-based language is used to embed “content” within the KQML language, providing a self-describing data representation using various character sets. The ARM Framework includes system agents including in each Agent Domain a Resolver for keeping track of asset logical locations, an Agent Name Server (ANS) for keeping track of security access to the assets, and the “Yellow Pages” containing the Advertised System Knowledge (ASK) agent for keeping track of the capabilities of the Asset Management Agents.

Claims

1. A system for associative managing of distributed multimedia assets, comprising:

a plurality of distributed resources, including storage resources that store the multimedia assets,

a plurality of user applications for operating on the multimedia assets,

a plurality of asset management agents, the asset management agents including resource management agents coupled to the resources for managing the resources and user agents coupled to the user applications, and

an asset/resource management framework coupled to the asset management agents for managing the association of the multimedia assets,

wherein the asset management agents communicate with each other and with the resources and the user applications, and

wherein the asset/resource management framework comprises a resolver agent that tracks the multimedia assets stored on the storage resources and associates multimedia assets of multiple versions with each other.

2. A system according to claim 1, wherein each independently addressable asset has a universal resource locator (URL) associated therewith and a resource management agent assigns a new URL to a new asset when the asset is created and registers the new URL with the resolver agent.

3. A system according to claim 2, wherein the URL includes:

a device name that defines the storage resource by which the asset is stored,

a location, and

an asset name.

4. A system according to claim 1, for managing assets that include a set of logically equivalent assets, wherein the resolver agent creates a universal resource name (URN) for the set of logically equivalent assets.

5. A system according to claim 4, wherein the URN includes a globally unique identification (UID) for the set of logically equivalent assets and a revision identifier (REV).

6. A system according to claim 5, wherein each independently addressable asset has a universal resource locator (URL) associated therewith and a resource management agent assigns a new URL to a new asset when the new asset is created and registers the new URL with the resolver agent.

7. A system according to claim 5, wherein each independently addressable asset has a universal resource locator (URL) associated therewith, a resource management agent assigns a new URL to a new asset when the new asset is created as a member of the set of logically equivalent assets and registers the new URL with the resolver agent, and the resolver agent creates a new URN, including the UID for the set of logically equivalent assets and an incremented REV, and associates the new URL with the new URN.

8. A system according to claim 1, wherein the resources include database resources that store data and the resource management agents that manage the database resources each provide at least one database service.

9. A system according to claim 8, wherein the database service provided by a database resource has attributes that identify the data stored in the database, whether the database supports queries and whether the database is networked.

10. A system according to claim 1, wherein the resource management agents provide a transfer service for transferring a multimedia asset from a first storage resource to a second storage resource.

11. A system according to claim 1, comprising a capture services module coupled to a source of multimedia material for capturing such material and adding the captured multimedia material to the multimedia assets stored by the storage resources.

12. A system according to claim 11 wherein the capture services module is operative to capture high resolution material and equivalent low resolution material.

13. A system according to claim 11, wherein the capture services module is operative to capture multimedia material and metadata associated with the multimedia material.

14. A system according to claim 1, wherein the asset/resource management framework comprises an asset/resource management infrastructure coupled to the asset management agents and a plurality of system agents coupled to the asset/resource management infrastructure for routing data and queries to and from the asset management agents.

15. A system according to claim 1, wherein the asset management agents are organized as at least first and second agent domains including first and second asset/resource management frameworks respectively, and wherein each asset/resource management framework comprises a resolver agent that tracks multimedia assets stored on the storage resources to which the resource management agents of that agent domain are coupled.

16. A system according to claim 15, wherein a given asset has multiple versions and the resolver agent that tracks a given asset associates the multiple versions of said given asset with each other.

17. A system according to claim 16, wherein the resolver agent creates a universal resource name (URN) for a set of logically equivalent assets.

18. A system according to claim 17, wherein the URN includes a globally unique identification (UID) for the set of logically equivalent assets and a revision identifier (REV).

19. A system according to claim 18, wherein each independently addressable asset has a universal resource locator (URL) associated therewith and a resource management agent assigns a new URL to a new asset when the new asset is created and registers the new URL with the resolver agent.

20. A system according to claim 18, wherein each independently addressable asset has a universal resource locator (URL) associated therewith, a resource management agent assigns a new URL to a new asset when the new asset is created as a member of the set of logically equivalent assets and registers the new URL with the resolver agent, and the resolver agent creates a new URN, including the UID for the set of logically equivalent assets and an incremented REV, and the resolver agent associates the new URL with the new URN.

21. A method of associative managing of distributed multimedia assets comprising:

storing the multimedia assets on a plurality of distributed storage resources,

employing user applications to operate on the multimedia assets,

employing asset management agents to manage the storage resources and the user applications, the asset management agents communicating with each other and including resource management agents coupled to the storage resources for managing the storage resources and user agents coupled to the user applications,

employing an asset/resource management framework coupled to the asset management agents to manage the association of the asset, and

wherein the asset/resource management framework comprises a resolver agent that tracks the multimedia assets stored on the storage resources and associates multimedia assets of multiple versions with each other.

22. A method according to claim 21, comprising creating a universal resource name (URN) for a set of logically equivalent assets.

23. A method according to claim 22, wherein the URN includes a globally unique identification (UID) for the set of logically equivalent assets and also includes a revision identifier (REV).

24. A method according to claim 23, wherein each independently addressable asset has a universal resource locator (URL) associated therewith and the method includes assigning a new URL to a new asset when the new asset is created and registering the new URL.

25. A method according to claim 23, comprising associating a universal resource locator (URL) with each independently addressable asset, assigning a new URL to a new asset when the new asset is created as a member of the set of logically equivalent assets, registering the new URL, creating a new URN including the UID for the set of logically equivalent assets and an incremented REV, and associating the new URL with the new URN.

26. A method according to claim 23, wherein the URL includes:

a device name that defines the storage resource by which the asset is stored,
