Abstract

Embodiments relate to a method, computer program product, and a computer system for generating a tailored schema description of a web service from a predefined schema description of the web service is provided. The predefined schema provides a machine readable description of operations performed by the web service and a message format for communication with the web service. A subset of the predefined schema required to support an identified operation may be calculated based on at least one example message. A tailored schema may then be generated based on the calculated subset of the predefined schema.

Claims

1. A method of generating a tailored schema description of a web service from a predefined schema description of the web service, the predefined schema providing a machine readable description of operations performed by the web service and a message format for communication with the web service, the method comprising:

identifying an operation of the web service to be supported by the tailored schema;

for the identified operation, providing at least one example message;

calculating a subset of the predefined schema for supporting the identified operation based on the at least one example message; and

generating the tailored schema based on the calculated subset of the predefined schema.

2. The method of claim 1, wherein the generating the tailored schema comprises editing the predefined schema based on the calculated subset.

3. The method of claim 1, wherein the generating the tailored schema comprises:

removing elements from the predefined schema which are not in the calculated subset of the predefined schema; and

defining remaining non-removed elements as forming the tailored schema.

4. The method of claim 1, wherein the calculating the subset of the predefined schema comprises:

identifying elements of the at least one example message; and

determining, for each identifying message element, one or more associated schema elements of the predefined schema.

5. The method of claim 1, wherein the predefined schema description comprises a machine-readable definition of the message format.

6. The method of claim 5, wherein the machine-readable definition of the message format is represented in an extensible Markup Language (XML).

7. The method of claim 6, wherein the machine readable definition comprises a Web Service Description Language (WSDL) document.

8. The method of claim 1, wherein the at least one example message contains all of the required data fields.

9. A computer program product for generating a tailored schema description of a web service from a predefined schema description of the web service, the predefined schema providing a machine readable description of operations performed by the web service and a message format for communication with the web service, wherein the computer program product comprises:

a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code configured to perform the method of;

identifying an operation of the web service to be supported by the tailored schema;

for the identified operation, providing at least one example message;

calculating a subset of the predefined schema for supporting the identified operation based on the at least one example message; and

generating the tailored schema based on the calculated subset of the predefined schema.

10. The computer program product of claim 9, wherein the generating the tailored schema comprises editing the predefined schema based on the calculated subset.

11. The computer program product of claim 9, wherein the generating the tailored schema comprises:

removing elements from the predefined schema which are not in the calculated subset of the predefined schema; and

defining remaining non-removed elements as forming the tailored schema.

12. The computer program product of claim 9, wherein the calculating the subset of the predefined schema comprises:

identifying elements of the at least one example message; and

determining, for each identifying message element, one or more associated schema elements of the predefined schema.

13. The computer program product of claim 9, wherein the predefined schema description comprises a machine-readable definition of the message format.

14. The computer program product of claim 13, wherein the machine-readable definition of the message format is represented in an extensible Markup Language (XML).

15. The computer program product of claim 14, wherein the machine readable definition comprises a Web Service Description Language (WSDL) document.

16. A computer system adapted to generate a tailored schema description of a web service from a predefined schema description of the web service, the system for generating a tailored schema description of a web service from a predefined schema description of the web service, the predefined schema providing a machine readable description of operations performed by the web service and a message format for communication with the web service, the system comprising:

one or more processors configured to perform a method comprising;

identifying an operation of the web service to be supported by the tailored schema;

for the identified operation, providing at least one example message;

calculating a subset of the predefined schema for supporting the identified operation based on the at least one example message; and

generating the tailored schema based on the calculated subset of the predefined schema.

17. The computer system of claim 16, wherein the generating the tailored schema comprises editing the predefined schema based on the calculated subset.

18. The computer system of claim 16, wherein the generating the tailored schema comprises:

removing elements from the predefined schema which are not in the calculated subset of the predefined schema; and

defining remaining non-removed elements as forming the tailored schema.

19. The computer system of claim 16, wherein the calculating the subset of the predefined schema comprises:

identifying elements of the at least one example message; and

determining, for each identifying message element, one or more associated schema elements of the predefined schema.

20. The computer system of claim 16, wherein the predefined schema description comprises a machine-readable definition of the message format.
