Abstract

Methods, systems, and machine-readable mediums are disclosed for providing resource interface descriptions with policy parameters. In one embodiment, a method comprises intercepting, at a framework, a request for a resource interface description. The resource interface description is obtained at the framework and at least one policy associated with the resource is determined. For each of the determined policies, one or more policy parameters associated with the policy are determined.

Claims

1. A method comprising:

intercepting, at a framework, a request for a resource interface description, the request associated with a requester;

obtaining, at the framework, the resource interface description;

determining, at the framework, at least one policy associated with the resource;

for each of the determined policies, determining, at the framework, one or more policy parameters associated with the respective policy; and

transmitting, from the framework, the resource interface description and the policy parameters to the requester.

2. The method of claim 1, wherein transmitting the resource interface description and the policy parameters comprises:

modifying the resource interface description to include the policy parameters; and

transmitting the modified resource interface description to the requester.

3. The method of claim 2, wherein modifying the resource interface description comprises modifying a web services discover response to include the policy parameters.

4. The method of claim 3, wherein modifying the web services discover response comprises adding the policy parameters to a header of the web services discover response.

5. The method of claim 1, wherein determining the at least one policy comprises determining the at least one policy is applicable to the requester.

6. The method of claim 1, wherein determining the at least one policy comprises invoking a policy to be applied to the request for the resource interface description.

7. The method of claim 1, wherein determining one or more policy parameters comprises determining one or more policy parameters used by an authentication policy associated with the resource.

8. The method of claim 1, wherein determining one or more policy parameters comprises determining one or more policy parameters used by a billing policy associated with the resource.

9. The method of claim 1, wherein determining the one or more policy parameters comprises determining one or more policy parameters used by a prioritization policy associated with the resource.

10. The method of claim 1, wherein transmitting the resource description and the policy parameters comprises transmitting a Simple Object Access Protocol (SOAP) message.

11. The method of claim 1, wherein obtaining the resource interface description comprises obtaining the resource interface description from a register associated with the resource.

12. The method of claim 11, wherein obtaining the resource interface description from the register comprises obtaining the resource interface description from a Universal Description Discovery and Integration (UDDI) register.

13. The method of claim 1, wherein intercepting the request comprises intercepting a web services discovery message.

14. The method of claim 1, further comprising:

receiving, at the framework, a communication to access the resource; and

determining the communication does not include at least one missing policy parameter needed to process the communication.

15. The method of claim 14, further comprising transmitting an error in response to the communication.

16. The method of claim 14, further comprising transmitting a communication requesting the missing policy parameter.

17. The method of claim 14, further comprising transmitting a policy interface description in response to the communication.

18. A method comprising:

intercepting, at a framework, a communication from a resource to register a resource description with a register;

determining, at the framework, at least one policy associated with the resource;

for each of the determined policies, determining, at the framework, one or more policy parameters associated with the respective policy; and

transmitting, from the framework, the resource interface description and the policy parameters to the register.

19. A system comprising:

a communications interface to intercept a request, from a requester, for a resource interface description;

logic, to obtain the resource interface description, to determine at least one policy associated with the resource, and to determine one or more policy parameters associated with each of the determined policies; and

wherein the communications interface is further to transmit the resource interface description and the policy parameters to the requester.

20. The system of claim 19, further comprising the at least one policy, communicatively coupled with the logic, and wherein the logic determines the policy parameters by obtaining the policy parameters from the at least one policy.

21. The system of claim 19, further comprising the resource.

22. The system of claim 19, further comprising a register associated with the resource, the logic to obtain the resource description from the register.

23. A system comprising:

a communication interface, to intercept a communication from a resource to register a resource description with a register; and

logic to determine at least one policy associated with the resource and to determine one or more policy parameters associated with each of the determined policies; and

wherein the communications interface is further to transmit the resource interface description and the policy parameters to the register.

24. At least one machine-readable medium, having stored thereon sequences of instructions, which, when executed by a machine cause the machine to:

intercepting, at a framework, a request for a resource interface description, the request associated with a requester;

obtaining, at the framework, the resource interface description;

determining, at the framework, at least one policy associated with the resource;

for each of the determined policies, determining, at the framework, one or more policy parameters associated with the respective policy; and

transmitting, from the framework, the resource interface description and the policy parameters to the requester.
