Abstract

A system, method and device for creating a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression, including specifying rights expression information indicating a manner of use of an item, the rights expression information including at least one element, the element having a variable and corresponding value for the variable; generating a profile of the rights expression information, including removing the value for the variable from the element; and generating an identification for the profile, whereby the rights expression information can be enforced on the device based on the variable and the identification for the profile.

Claims

1. A method for creating a rights expression for association with an item of digital content for use in a digital rights management system for controlling use of the item of digital content in accordance with the rights expression, said method comprising:

specifying rights expression information using a computer, said rights expression information indicating a manner of use of an item of digital content, said rights expression information including at least one element, said element having a variable and corresponding value for said variable;

generating a template of said rights expression information using a computing device, including removing said value for said variable from said element;

generating an identification for said template; and

transmitting said identification for said template to a device adapted to situationally determine said variable and enforce said rights expression information based on said variable and said identification for said template,

whereby said rights expression information can be enforced on a device based on said variable and said identification for said template.

2. The method of claim 1, wherein said transmitting step comprises:

transmitting one or more variables associated with said identification for said template in a predetermined order and situationally determining untransmitted variables.

3. The method of claim 1, wherein said transmitting step comprises:

transmitting one or more variables associated with said identification for said template in a non-predetermined order and situationally determining untransmitted variables.

7. The method of claim 1, further comprising:

transmitting said identification for said template to a device adapted to follow machine-interpretable reconstruction instructions to determine said variable and enforce said rights expression information based on said variable and said identification for said template.

8. The method of claim 7, wherein said transmitting step comprises:

transmitting one or more variables associated with said identification for said template in a predetermined order, determining the machine-interpretable reconstruction instructions associated with said template, and determining untransmitted variables according to said machine-interpretable reconstruction instructions.

9. The method of claim 7, wherein said transmitting step comprises:

transmitting one or more variables associated with said identification for said template in a non-predetermined order, determining the machine-interpretable reconstruction instructions associated with said template, and determining the untransmitted variables according to said machine-interpretable reconstruction instructions.

4. A method for creating a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression, said method comprising:

specifying rights expression information indicating a manner of use of an item, said rights expression information including at least one element, said element having a variable and corresponding value for said variable;
