Abstract

Embodiments of the invention allow structured data to be transferred between a source application and a target application that process structured data in different formats. For example, structured data may have a set of associated rules which transform the structured data based on a set of variables. The source application may register variable definitions for each of the variables in a registry. The target application may read the registry and register values for each of the rule variables. Once values are registered for the variables, the source application may transfer the structured data to a transformation engine that applies the rules, using the registered values for the variables, to transform the structured data into a format compatible with the target application. In doing so, the transformation engine can generate a document in any format compatible with the target application and subsequently transfer the generated document to the target application.

Claims

1. A computer-implemented method for transforming structured document data received from a source application for use by a target application, comprising:

receiving, from the source application, one or more variable definitions, wherein each variable definition defines a variable used to determine how to transform the structured document data, based on a specified value for each of the one or more variable definitions;

receiving, from the target application, a registered value for each of the one or more variable definitions, wherein the registered value for each of the one or more variable definitions indicates a format of the structured document data that is compatible with the target application;

receiving, from the source application, the structured document data, wherein the structured document data includes one or more embedded processing rules used to transform the structured document data, based on a value for each of the one or more variable definitions;

identifying the registered value for each of the one or more variable definitions;

applying the embedded processing rules to the structured document data, based on the registered value for each of the one or more variable definitions, to transform the structured document data to be compatible with the target application; and

transmitting the transformed structured document data to the target application.

2. The computer-implemented method of claim 1, further comprising, storing the variable definitions received from the source application in a registry.

3. The computer-implemented method of claim 2, further comprising, storing the registered value for each of the one or more variable definitions received from the target application in the registry.

4. The computer-implemented method of claim 1, wherein each variable definition includes at least a source application name, a variable name, and a variable type.

5. The computer-implemented method of claim 1, wherein the structured document data comprises an extensible markup language (XML) document composed according to a document type definition (DTD).

6. The computer-implemented method of claim 5, wherein at least one of the embedded processing rules comprises an Extensible Stylesheet Language Transformation (XSLT) selectively applied to the structured document data, based on one or more of the registered values for the variable definitions.

7. The computer-implemented method of claim 1, wherein transmitting the transformed structured document data to the target application comprises transmitting the transformed structured document data to a plurality of target applications.

8. A computer-readable storage medium containing a program which, when executed, performs an operation for transforming structured document data received from a source application for use by a target application, comprising:

receiving, from the source application, one or more variable definitions, wherein each variable definition defines a variable used to determine how to transform the structured document data;

receiving, from the target application, a registered value for each of the one or more variable definitions, wherein the registered value for each of the one or more variable definitions indicates a format of the structured document data that is compatible with the target application;

receiving, from the source application, the structured document data, wherein the structured document data includes one or more embedded processing rules used to transform the structured document data, based on a value for each of the one or more variable definitions;

identifying the registered value for each of the one or more variable definitions;

applying the embedded processing rules to the structured document data, based on the registered value for each of the one or more variable definitions, to transform the structured document data to be compatible with the target application; and

transmitting the transformed structured document data to the target application.

9. The computer-readable storage medium of claim 8, wherein the operation further comprises:

storing the variable definitions received from the source application in a registry.

10. The computer-readable storage medium of claim 9, further comprising, storing the registered value for each of the one or more variable definitions received from the target application in the registry.

11. The computer-readable storage medium of claim 8, wherein the structured document data comprises an extensible markup language (XML) document composed according to a document type definition (DTD).

12. The computer-readable storage medium of claim 11, wherein at least one of the embedded processing rules comprises an Extensible Stylesheet Language Transformation (XSLT) selectively applied to the structured document data, based on one or more of the registered values for the variable definitions.

13. The computer-readable storage medium of claim 8, wherein transmitting the transformed structured document data to the target application comprises transmitting the transformed structured document data to a plurality of target applications.

14. A system, comprising:

a processor; and

a memory containing a program, which, when executed by the processor, is configured to transform structured document data received from a source application for use by a target application by performing an operation comprising;

receiving, from the source application, one or more variable definitions, wherein each variable definition defines a variable used to determine how to transform the structured document data;

receiving, from the target application, a registered value for each of the one or more variable definitions, wherein the registered value for each of the one or more variable definitions indicates a format of the structured document data that is compatible with the target application;

receiving, from the source application, the structured document data, wherein the structured document data includes one or more embedded processing rules used to transform the structured document data, based on a value for each of the one or more variable definitions;

identifying the registered value for each of the one or more variable definitions;
