Abstract

Claims (42)

1. A computer system comprising:

a processor;

a storage device electrically connected to the processor;

an operating environment;

an interface for receiving data objects including a data change event, the data objects corresponding to information pertaining to an enterprise policy and in a predetermined format;

a first application for enabling a user to define a plurality of policies in an abstract manner for an enterprise, the plurality of policies being built using a domain-specific language that is structured in terms of an effect the policy will have on a target system;

a second application for selecting one or more policies to be applied to the events, the selection of the policies being specific to the enterprise; and

a third application for transforming the data objects by applying the one or more selected policies to the event by using XSL scripting code,

the application of the policies performing one or more of changing the event, hooking the event, binding the event with a template, and informing the data store that an action needs to be performed.

2. The computer system of claim 1 wherein the predetermined format and the domain-specific language are defined on extensible markup language (XML).

3. The computer system of claim 1 wherein the data objects are XML documents and the transformation uses at least one of an extensible stylesheet language (XSL) variable and an XSL template to apply the selected policy to the data objects.

4. The transformation engine computer system of claim 1 wherein the first application includes a separate document for storing the transformed data objects.

5. The transformation engine computer system of claim 1 wherein the first application further enables for setting up an XSL variable within the transformation that stores the information for later use.

6. The computer system of claim 1 wherein the second application utilizes an XSLT style sheet.

7. A computing system for use in a computer network, the computing system comprising:

a processor;

a storage device connected to the processor;

a main software application for providing bi-directional data sharing across directories, databases and applications on the computer network, the main software application working, at least in part, in response to XML events;

a data store that can send one or more XML documents back and forth to a transformation engine, the XML documents including XML events;

the transformation engine for taking the XML documents and applying the XML documents against an XSL style sheet or an XSL transformation to transform the XML events into a different type of event for a controlled application or service, the transformation engine comprising:

a first task for defining a plurality of policies in an abstract manner for an enterprise, each of the plurality of policies being built as XML data that is structured in terms of an effect the policy will have on a target system;

a second task for selecting one or more policies to be applied to the events, the selection of the policies being specific to the enterprise;

a third task for to applying the one or more selected policies to the event by using XSL scripting code, the application of the policies performing one or more of changing the event, hooking the event, binding the event with a template, and informing the data store that an action needs to be performed.

8. Computer readable media accessible by at least one computing system, the computer readable media having stored thereon computer executable instructions, that, when executed:

in a first process:

create a data object in a predetermined format, wherein the data object is associated with a policy, wherein the predetermined format defines a policy template and a policy variable, and

wherein the predetermined format is structured in terms of a final effect of the policy;

in a second process:

receive the data object;

transform at least one policy template, policy variable or combination of policy templates and policy variables within the data object into a policy section in the data object; and

modify the data object in conformance with the policy section.

9. The computer readable medium comprising computer executable instructions of claim 8 wherein one of the policy template and the policy variable comprises a portion written in a domain-specific language.

10. The computer readable medium comprising computer executable instructions of claim 8 wherein the policy section is scoped in complexity relative to at least one policy template, policy variable, or combination of policy templates and policy variables, and semantically identical to said policy template, policy variable, or combination of policy templates and policy variables.

11. The computer readable medium comprising computer executable instructions of claim 8 wherein the transforming one of a policy template, a policy variable, or a combination of policy templates and policy variables produces results with different scopes of complexity.

12. The computer readable medium comprising computer executable instructions of claim 8 wherein the transforming one of a policy template, a policy variable, or a combination of policy templates and policy variables is iterative.

13. The computer readable medium comprising computer executable instructions of claim 8 wherein the domain-specific language is defined on XML or formatted according to an XML-based specification.

14. The computer readable medium comprising computer executable instructions of claim 8 wherein the data object is formatted according to a first XML-based specification and at least one of the policy template or policy variable is formatted according to a second XML-based specification.

15. The computer readable medium comprising computer executable instructions of claim 8 wherein the transforming one of a policy template, a policy variable, or a combination of policy templates and policy variables is accomplished via an XSL processor.

16. The computer readable medium comprising computer executable instructions of claim 8 wherein the policy section is an XSL stylesheet.

17. The computer readable medium comprising computer executable instructions of claim 8 wherein at least one of the policy templates, policy variables, or combinations of policy templates and policy variables utilizes a second document.

18. The computer readable medium comprising computer executable instructions of claim 8 wherein at least one of transforming or modifying provides information to an outside receiver.

19. The computer readable medium comprising computer executable instructions of claim 8 wherein at least one of transforming or modifying reads or writes information in an outside data store.
