Abstract

A system and method for enforcing rights expressions, include specifying a repository rights expression indicating a manner of use of an item at a repository; and associating the repository rights expression with the repository. In a further embodiment, the system includes one or more repositories having associated therewith rights expressions further indicating a condition of use of the item at the repository. In a further embodiment, a repository for use in the system, includes a processor module configured to process the rights expression associated with the repository; and a determination module configured to determine based on the rights expression associated with the repository what action the repository is to take when the repository processes or receives a request for the item. The manner of use or condition of use indicates what action the repository is to take when the repository processes or receives a request for the item.

Claims

1. A computer implemented method for enforcing rights expressions specifying manners of use of an item, said method comprising:

recording, by a computing device, a repository rights expression on computer readable media as a data structure that is readable by a repository computing device, said repository rights expression indicating a manner of use of an item at said repository computing device;

associating said repository rights expression with said repository computing device;

recording by a computing device, an item rights expression on computer readable media as a data structure that is readable by a repository computing device, said item rights expression indicating a manner of use of said item;

associating said item rights expression with said item; and

determining, by said repository computing device, what action said repository computing device is to take when said repository computing device processes said item based on a combination of said repository rights expression associated with said repository computing device and said item rights expression associated with said item,

wherein said manner of use of said item at said repository computing device indicates at least one of what action said repository computing device is to take when said repository computing device processes said item and what action said repository computing device is to take when said repository computing device receives a request for said item.

2. The method of claim 1, wherein said item includes said item rights expression associated therewith and indicating said manner of use of said item.

3. The method of claim 1, wherein said repository rights expression applies to at least one of all items that said repository computing device processes and all requests for items received by said repository computing device.

4. The method of claim 1, wherein said repository rights expression applies to one collection of specific items that said repository computing device processes and specific requests for items received by said repository computing device.

5. The method of claim 1, further comprising:

specifying a plurality of said repository rights expression indicating respective manners of use of said item at said repository computing device; and

associating the plural repository rights expressions with said repository computing device of said item.

6. The method of claim 1, wherein said step of specifying a repository rights expression comprises:

specifying in said repository rights expression that the item rights expression associated with said item overrules said repository rights expression,

wherein said combination in said step of determining considers said item rights expression overruling said repository rights expression.

7. The method of claim 1, wherein said step of specifying a repository rights expression comprises:

specifying in said repository rights expression that said repository rights expression overrules the item rights expression associated with said item,

wherein said combination in said step of determining considers said repository rights expression overruling said item rights expression.

8. The method of claim 1, wherein said item includes a pointer to said repository and said method further comprises:

providing said item to said repository computing device based on said pointer.

9. The method of claim 1, wherein said step of determining comprises:

determining the actions to be taken by said repository computing device based on a characteristic of said item.

10. The method of claim 1, wherein said item includes at least one of digital content, digital goods, digital services, non-digital content, non-digital goods and non-digital services.

11. A computer system comprising one or more memories and one or more processors and configured to perform the method of claim 1.

12. A computer-readable medium bearing instructions arranged to cause one or more processors to perform the method of claim 1.

16. The method of claim 1, further comprising:

performing a determined action by said repository on said item.

27. The method of claim 1, further comprising:

performing an action on said item by said repository that is determined by said step of determining.

28. The method of claim 1, wherein said step of specifying an item rights expression comprises:

specifying in said item rights expression that the repository rights expression associated with said repository overrules said item rights expression,

wherein said combination in said step of determining considers said repository rights expression overruling said item rights expression.

29. The method of claim 1, wherein said step of specifying an item rights expression comprises:

specifying in said item rights expression that said item rights expression overrules the repository rights expression associated with said repository,

wherein said combination in said step of determining considers said item rights expression overruling said repository rights expression.

13. A system for enforcing rights expressions specifying manners of use of an item, said system comprising:

means for specifying a repository rights expression indicating a manner of use of an item at a repository;

means for associating said repository rights expression with said repository;

means for specifying an item rights expression indicating a manner of use of said item;

means for associating said item rights expression with said item; and

means for determining what action said repository is to take when said repository processes said item based on a combination of said repository rights expression associated with said repository and said item rights expression associated with said item,

wherein said manner of use of said item at said repository indicates at least one of what action said repository is to take when said repository processes said item and what action said repository is to take when said repository receives a request for said item.

14. The system of claim 13, wherein said means for specifying, said means for determining, and said means for associating comprise devices of a computer system.

15. The system of claim 13, wherein said means for specifying, said means for determining, and said means for associating comprise software devices.

17. The system of claim 13, further comprising:

means for performing a determined action by said repository on said item.

18. The system of claim 13, wherein said item includes said item rights expression associated therewith and indicating said manner of use of said item.

19. The system of claim 13, wherein said repository rights expression applies to at least one of all items that said repository processes and all requests for items received by said repository.

20. The system of claim 13, wherein said repository rights expression applies to one collection of specific items that said repository processes and specific requests for items received by said repository.

21. The system of claim 13, further comprising:

means for specifying a plurality of said repository rights expression indicating respective manners of use of said item at said repository; and

means for associating the plural repository rights expressions with said repository of said item.

22. The system of claim 13, wherein said means for specifying a repository rights expression comprises:

means for specifying in said repository rights expression that the item rights expression associated with said item overrules said repository rights expression,

wherein said combination in said means for determining considers said item rights expression overruling said repository rights expression.

23. The system of claim 13, wherein said means for specifying a repository rights expression comprises:

means for specifying in said repository rights expression that said repository rights expression overrules the item rights expression associated with said item,

wherein said combination in said means for determining considers said repository rights expression overruling said item rights expression.

24. The system of claim 13, wherein said item includes a pointer to said repository and said system further comprises:

means for providing said item to said repository based on said pointer.

25. The system of claim 13, wherein said determining means comprises:

means for determining the actions to be taken by said repository based on a characteristic of said item.
