Abstract

Systems and techniques, including computer program products, for managing different representations of information. The systems and techniques can include a method that includes receiving information identifying a first customization setting, receiving information identifying a second customization setting, and mapping the customized format of the data variable in the first data processing system to the customized format of the data variable in the second data processing system. The first customization setting can describe a customized representation of information in a data variable in a first data processing system. The second customization setting can describe a customized format of the data variable in the second data processing system.

Claims

1. A computer-implemented method for managing different representations of information, comprising:

receiving information describing a first representation of data variable information in a first data structure in a first data processing system;

receiving information describing a second representation of the data variable information in the first data structure in a second data processing system; and

mapping the first representation of the data variable information to the second representation of the data variable information, the mapping comprising;

identifying a correspondence between the first representation and the second representation using a set of data processing activities performed in accordance with a first set of machine-readable instructions,

representing the correspondence using the set of data processing activities performed in accordance with the first set of machine-readable instructions, and

making the correspondence between the first representation and the second representation available for changing the first representation of the data variable information to the second representation of the data variable information.

2. The method of claim 1, wherein:

mapping the first representation to the second representation further comprises establishing a second set of machine readable instructions for changing the first representation of the data variable information to the second representation of the data variable information; and

making the correspondence available comprises making the second set of machine readable instructions available.

3. The method of claim 2, wherein establishing the second set of machine-readable instructions comprises establishing a criterion for identifying a data variable in a first data structure.

4. The method of claim 2, wherein establishing the second set of machine-readable instructions comprises establishing an extensible stylesheet language (XSL) file that describes how to change the first representation of the data variable information.

5. The method of claim 2, wherein establishing the second set of machine-readable instructions comprises:

receiving a framework for instructions; and

inserting instructions into the framework.

6. The method of claim 2, wherein establishing the second set of machine-readable instructions comprises selecting a germane instruction for transforming the first representation to the second representation from a collection of instructions for transforming the first representation to the second representation.

7. The method of claim 2, wherein the second set of machine-readable instructions comprises instructions for identifying the data variable in a data structure.

8. The method of claim 7, wherein the instructions for identifying the data variable comprise an Xpath expression for identifying an object of an object class that includes the data variable.

9. The method of claim 1, further comprising changing the first representation of the data variable information in the data variable in the first data processing system to the second representation of the data variable information in the second data processing system using the correspondence between the first representation and the second representation.

10. The method of claim 1, further comprising receiving a trigger for the mapping, the trigger identifying a data object class that includes the data variable.

11. The method of claim 1, further comprising storing results of the mapping in a collection of mapping results.

12. The method of claim 1, wherein the information describing the first representation of data variable information comprises instructions for locating the information in the first data processing system.

13. The method of claim 1, wherein the information describing the first representation of data variable information comprises the first representation of data variable information.

14. The method of claim 1, further comprising:

receiving instructions for data interfacing with the first data processing system; and

adding the interfacing instructions to results of the mapping.

15. The method of claim 1, wherein the first representation specifies a language of the information in the data variable.

16. The method of claim 1, wherein the first representation specifies a unit of the information in the data variable.

17. The method of claim 1, wherein the first representation specifies a notation of the information in the data variable.

18. The method of claim 1, wherein the first representation specifies a formal of the information in the data variable.

30. The method of claim 1, wherein making the correspondence between the first representation and the second representation available comprises providing the correspondence in a directory of mapping information.

19. A computer program product, tangibly embodied in one or more machine-readable storage devices, for managing different representations of information, the computer program product being operable to cause one or more data processing apparatus to:

receive a data variable in a data structure, wherein data variable information in the data variable has a first representation associated with a first system;

receive a description of a second representation of the data variable information, wherein the second representation is associated with a second system;

identify and represent a correspondence between the first representation and the second representation to generate a set of mapping information; and

change the data variable information from the first representation to the second representation in accordance with the set of mapping information and separately from any change to the structure of the data structure; and

make the data variable information having the second representation available in the data structure.

20. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to:

receive the data variable information formatted in accordance with a first customization setting of the first system;

receive a second customization setting of the second system, wherein the first customization setting and the second customization setting specify at least one of a language, a format, and a unit of the data variable information; and

change the data variable information from being in accordance with the first customization setting to being in accordance with the second customization setting.

21. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to receive a current description of the first representation.

22. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to receive the description of the second representation from the second system.

23. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to:

receive the data variable in a data object including a collection of further variables;

receive descriptions of further representations of information in the further variables, the further representations associated with the second system; and

change representations of data variable information in the further variables to the further representations.

24. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to change the data structure to a second data structure associated with the second system.

25. The computer program product of claim 19, wherein the product is also operable to cause the data processing apparatus to

establish machine-readable instructions for changing the data variable information from the first representation to the second representation;

and

make the machine readable instructions available.
