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 of a web service from a predefined schema of the web service, the predefined schema providing a machine readable description of operations performed by the web service and an Extensible Markup Language (XML) message format for communication with the web service, the method comprising:

receiving, from an end user, an indication of a particular operation of the web service to be supported by the tailored schema, the particular operation selected by the end user from the operations performed by the web service;

receiving, from the end user, at least one example XML message that the tailored schema should support for requesting the particular operation;

determining, based at least in part on the at least one example XML message, a minimal subset of schema elements of the predefined schema required to support the particular operation;

generating the tailored schema to include only the minimal subset of schema elements of the predefined schema;

receiving an XML message requesting the particular operation; and

performing the particular operation using the tailored schema in response to receiving the XML message.

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

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

removing each element from the predefined schema other than the minimal subset of schema elements; and

defining remaining elements of the predefined schema as forming the tailored schema.

4. The method of claim 1, wherein the determining the minimal subset of schema elements of the predefined schema comprises:

identifying message elements of the at least one example XML message;

determining, for each message element of the at least one example XML message, a respective at least one corresponding schema element of the predefined schema; and

determining that the minimal subset of schema elements comprises each respective at least one corresponding schema element.

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

6. The method of claim 5, wherein the machine readable definition comprises a Web Service Description Language (WSDL) document.

7. A computer program product for generating a tailored schema of a web service from a predefined schema of the web service, the predefined schema providing a machine readable description of operations performed by the web service and an Extensible Markup Language (XML) message format for communication with the web service, wherein the computer program product comprises:

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

receiving, from an end user, an indication of a particular operation of the web service to be supported by the tailored schema, the particular operation selected by the end user from the operations performed by the web service;

receiving, from the end user, at least one example XML message that the tailored schema should support for requesting the particular operation;

determining, based at least in part on the at least one example XML message, a minimal subset of schema elements of the predefined schema required to support the particular operation;

generating the tailored schema to include only the minimal subset of schema elements of the predefined schema;

receiving an XML message requesting the particular operation; and

performing the particular operation using the tailored schema in response to receiving the XML message.

8. The computer program product of claim 7, wherein the generating the tailored schema comprises editing the predefined schema based on the minimal subset of schema elements.

9. The computer program product of claim 7, wherein the generating the tailored schema comprises:

removing each element from the predefined schema other than the minimal subset of schema elements; and

defining remaining elements of the predefined schema as forming the tailored schema.

10. The computer program product of claim 7, wherein the determining the minimal subset of schema elements of the predefined schema comprises:

identifying message elements of the at least one example XML message;

determining, for each message element of the at least one example XML message, a respective at least one corresponding schema element of the predefined schema; and

determining that the minimal subset of schema elements comprises each respective at least one corresponding schema element.

11. The computer program product of claim 7, wherein the predefined schema comprises a machine-readable definition of the XML message format.

12. The computer program product of claim 11, wherein the machine readable definition comprises a Web Service Description Language (WSDL) document.

13. A computer system adapted to generate a tailored schema of a web service from a predefined schema 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;

receiving, from an end user, an indication of a particular operation of the web service to be supported by the tailored schema, the particular operation selected by the end user from the operations performed by the web service;

receiving, from the end user, at least one example XML message that the tailored schema should support for requesting the particular operation;

determining, based at least in part on the at least one example XML message, a minimal subset of schema elements of the predefined schema required to support the particular operation;

generating the tailored schema to include only the minimal subset of schema elements of the predefined schema;

receiving an XML message requesting the particular operation; and

performing the particular operation using the tailored schema in response to receiving the XML message.

14. The computer system of claim 13, wherein the generating the tailored schema comprises editing the predefined schema based on the minimal subset of schema elements.

15. The computer system of claim 13, wherein the generating the tailored schema comprises:

removing each element from the predefined schema other than the minimal subset of schema elements; and

defining remaining elements of the predefined schema as forming the tailored schema.

16. The computer system of claim 13, wherein the determining the minimal subset of schema elements of the predefined schema comprises:

identifying message elements of the at least one example XML message;

determining, for each message element of the at least one example XML message, a respective at least one corresponding schema element of the predefined schema; and

determining that the minimal subset of schema elements comprises each respective at least one corresponding schema element.

17. The computer system of claim 13, wherein the predefined schema comprises a machine-readable definition of the XML message format.
