Abstract

Technologies are described herein for providing a machine-readable and enforceable license. A first interface and a second interface are provided. A first set of input and a second set of input are received. The first set of input defines a range of allowable uses for a content item generated by a user. The second set of input defines an amount of compensation for the user for a sale of the content item. A high-level representation of a license is generated based on the first set of input and the second set of input.

Claims

1. A method for generating a machine-readable and enforceable license, the method comprising:

receiving a first set of input defining a range of allowable uses for a content item generated by a user;

receiving a second set of input defining an amount of compensation for the user for a sale of the content item; and

generating a high-level representation of a license based on the first set of input and the second set of input.

2. The method of claim 1, further comprising inserting a pointer into the high-level representation of the license, the pointer associating the high-level representation of the license to an object code representation of the license.

3. The method of claim 1, further comprising enforcing the sale of the content item based on the high-level representation of the license.

4. The method of claim 1 wherein generating a high-level representation of a license based on the first set of input and the second set of input comprises generating a schema representation of the license based on the first set of input and the second set of input.

5. The method of claim 4, wherein generating a schema representation of the license based on the first set of input and the second set of input comprises generating an Extensible Markup Language (XML) representation of the license based on the first set of input and the second set of input.

6. The method of claim 1, wherein generating a high-level representation of a license based on the first set of input and the second set of input comprises generating a programming language representation of the license based on the first set of input and the second set of input.

7. The method of claim 1, wherein receiving a first set of input defining a range of allowable uses for a content item generated by a user comprises:

providing a list containing a plurality of allowable uses; and

receiving a selection of at least one of the plurality of allowable uses.

8. The method of claim 7, wherein the list comprises one or more of a number of computing devices that can access the content item, a number of times that the content item can be accessed, a length of time for which the content item can be accessed, a number of times that the content item can be transferred, a number of times that the content item can be copied, a number of times that a computer-readable medium containing the content item can be created, and a type of use for which the content item can be accessed.

9. The method of claim 1, wherein receiving a second set of input defining an amount of compensation for the user for a sale of the content item comprises:

providing a list containing a plurality of compensation options; and

receiving a selection of at least one of the plurality of compensation options.

10. The method of claim 9, wherein the list comprises one or more of a no fee option, a flat fee option, a variable fee option, and a revenue sharing fee option.

11. The method of claim 1, wherein the content item generated by the user comprises a multimedia file.

12. The method of claim 1, wherein the content item generated by the user comprises an application plug-in.

13. The method of claim 1, the method further comprising:

generating a digital certificate comprising digests of the high-level representation of the license and the content item, the digests digitally signed with a private key; and

associating the digital certificate with the high-level representation of the license for validating the high-level representation of the license.

14. A method for generating a machine-readable and enforceable license (134), the method comprising:

receiving a first selection of at least one use for a content item generated by a first user, the at least one use defining an allowable use of the content item by a second user;

receiving a second selection of at least one compensation option, the at least one compensation option defining a compensation the first user is to receive for a sale of the content item; and

generating a schema representation of a license based on the first selection and the second selection.

15. The method of claim 14, further comprising inserting a pointer into the schema representation of the license, the pointer associating the schema representation of the license to an object code representation of the license.

16. The method of claim 14, further comprising enforcing the sale of the content item based on the schema representation of the license.

17. The method of claim 14, the method further comprising:

generating a digital certificate comprising digests of the schema representation of the license and the content item, the digests digitally signed with a private key; and

associating the digital certificate with the schema representation of the license for validating the schema representation of the license.

18. A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to:

provide a first list including a plurality of allowable uses of a content item generated by a first user;

receive a first selection of at least one allowable use from the first list;

provide a second list including a plurality of compensation options for compensating the first user for a sale of the content item;

receive a second selection of at least one compensation option from the plurality of compensation options;

generating a schema representation of a license based on the first selection and the second selection;

generating a digital certificate comprising digests of the schema representation of the license and the content item, the digests digitally signed with a private key; and

associating the digital certificate with the schema representation of the license for validating a source of the schema representation of the license, validating that no changes have been made to the schema representation of the license, and validating that the schema representation of the license is tied to the content item.

19. The computer-readable medium of claim 18 having further computer-executable instructions stored thereon which, when executed by a computer, cause the computer to enforce the sale of the content item utilizing the schema code representation of the license.

20. The computer-readable medium of claim 18, wherein the schema representation of the license is machine-independent.
