Abstract

The present invention provides an extensible dependency management framework and method. Specifically, the present invention provides dependency management handler(s) and dispatcher(s) (e.g., revalidation and/or refactoring). The handlers are created and registered by users of the framework. When a change to a resource is detected, a notification is received by a dispatcher from an external caller. Upon receipt, the dispatcher will query an index to identify dependents, and then call a dependency management handler associated with the changed resource to obtain and implement updates for the dependents. In so doing, a list of the dependents will be provided to the dependency management handler.

Claims

1. An extensible dependency management framework, comprising:

at least one computer including;

a dispatcher system for creating and registering a set of dependency management dispatchers, wherein the set of dependency management dispatchers receive notifications of changes to resources;

a handler system for creating and registering a set of dependency management handlers that is distinct from the set of dependency management dispatchers, wherein each dependency management handler performs change management update tasks for a set of dependents of a changed resource; and

a change management system for receiving notifications of changes to resources from the set of dependency management dispatchers, for querying an index to identify dependents of the changed resources, and for calling the set of dependency management handlers associated with the changed resources to update the dependents.

2. The extensible dependency management framework of claim 1, wherein the set of dependency management handlers comprises at least one of:

a refactoring hander or a revalidation handler, and wherein the set of dependency management dispatchers comprises at least one of;

a refactoring dispatcher or a revalidation dispatcher.

3. The extensible dependency management framework of claim 1, wherein the set of dependency management dispatchers receive the notifications from external callers.

4. The extensible dependency management framework of claim 1, wherein the dependency management framework provides resource level management and element level management of the changes to the resources.

5. The extensible dependency management framework of claim 1, wherein the change management system further identifies the dependents to the set of dependency management handlers.

6. The extensible dependency management framework of claim 1, wherein the set of dependency management handlers obtains updates to the dependents, and manages implementation of the updates in response to the calls received from the change management system.

7. An extensible dependency management method, comprising:

creating and registering a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is associated with a resource;

receiving a notification of a change to the resource from the dependency management dispatcher;

querying an index to identify a set of dependents of the changed resource;

calling the dependency management handler associated with the changed resource to update the set of dependents; and

implementing the updates using the dependency management handler.

8. The extensible dependency management method of claim 7, further comprising receiving the notification at the dependency management dispatcher from an external caller.

9. The extensible dependency management method of claim 7, wherein the dependency management handler is selected from a group consisting of:

a refactoring hander and a revalidation handler, and wherein the dependency management dispatcher is selected from a group consisting of;

a refactoring dispatcher and a revalidation dispatcher.

10. The extensible dependency management method of claim 7, further comprising:

obtaining an update to one of the set of dependents; and

implementing the update using a dependency management handler associated with the one of the set of dependents.

11. A program product stored on at least one computer readable storage medium for managing dependency updates, the at least one computer readable storage medium comprising program code for causing a computer system to:

create and register a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is associated with a resource;

receive a notification of a change to the resource from the dependency management dispatcher;

query an index to identify a set of dependents of the changed resource;

call the dependency management handler associated with the changed resource to update the set of dependents; and

implement the updates using the dependency management handler.

12. The program product of claim 11, wherein the notification is received by the dependency management dispatcher from an external caller.

13. The program product of claim 11, wherein the dependency management handler is selected from a group consisting of:

a refactoring hander and a revalidation handler, and wherein the dependency management dispatcher is selected from a group consisting of;

a refactoring dispatcher and a revalidation dispatcher.

14. The program product of claim 11, wherein the at least one computer readable storage medium further comprises program code for causing the computer system to:

obtain updates to the set of dependents; and

implement the updates.

15. A method for deploying a system for managing dependency updates, comprising:

providing a computer infrastructure being operable to;

create and register a dependency management dispatcher and a dependency management handler distinct from the dependency management dispatcher, wherein the dependency management handler is associated with a resource;

receive a notification of a change to the resource from a dependency management dispatcher;

query an index to identify a set of dependents of the changed resource;

call the dependency management handler associated with the changed resource to update the set of dependents; and

implement the updates using the dependency management handler.

16. The method of claim 15, wherein the notification is received by the dependency management dispatcher from an external caller.

17. The method of claim 15, wherein the dependency management handler is selected from a group consisting of:

a refactoring hander and a revalidation handler, and wherein the dependency management dispatcher is selected from a group consisting of;

a refactoring dispatcher and a revalidation dispatcher.

18. The method of claim 15, wherein the computer infrastructure is further operable to:

obtain updates to the set of dependents; and

implement the updates.
