Abstract

A method of creating a user interface includes receiving a request to create a UI for an application that is to use a service. First metadata is retrieved from a UI taxonomy that is an abstraction of a class of UIs, the first metadata providing that the created UI is a member of the class. Second metadata that defines the service is retrieved. The method comprises creating the UI by merging the first and second metadata. A computer system includes executable instructions that constitute a service, and a UI taxonomy that is an abstraction of a class of UIs. The system includes a UI generation module configured to retrieve first metadata from the UI taxonomy and second metadata that defines the service. The UI generation module generates a UI for the application by merging the first and second metadata.

Claims

1. A method of creating a user interface, the method comprising:

receiving a request to create a user interface (UI) for an application that is to use a service;

retrieving first metadata from a UI taxonomy that is an abstraction of a class of UIs, the first metadata providing that the created UI is a member of the class;

retrieving second metadata that defines the service; and

creating the UI by merging the first and second metadata.

2. The method of claim 1, wherein the service is comprised of a web service and a UI service.

3. The method of claim 2, wherein the UI service defines a look-and-feel aspect of the web service.

4. The method of claim 1, wherein the UI taxonomy is configured such that the class of UIs is consistent with a UI layout and a UI principle included in the UI taxonomy.

5. The method of claim 4, wherein at least one UI pattern and a UI topology are included in the UI layout.

6. The method of claim 4, wherein the UI taxonomy is further configured such that the class of UIs is consistent also with a UI environment included in the UI taxonomy.

7. The method of claim 1, wherein the service does not expose the second metadata, further comprising creating the second metadata using the service, wherein the second metadata can be retrieved upon creation.

8. The method of claim 1, wherein the UI is created to make the application a composite application for running on a first platform, wherein the UI taxonomy maps to UI objects for the first platform.

9. The method of claim 8, further comprising generating, in response to receiving a user input, another UI for use in running the application on a second platform.

10. The method of claim 9, wherein the other UI is generated by retrieving other metadata from another UI taxonomy that maps to UI objects for the second platform, and merging that other metadata with the second metadata that defines the service.

11. A computer program product tangibly embodied in an information carrier, the computer program product including instructions that, when executed, cause a processor to perform operations comprising:

receiving a request to create a user interface (UI) for an application that is to use a service;

retrieving first metadata from a UI taxonomy that is an abstraction of a class of UIs, the first metadata providing that the created UI is a member of the class;

retrieving second metadata that defines the service; and

creating the UI by merging the first and second metadata.

12. A computer system comprising:

executable instructions that constitute a service configured for use by an application in the computer system;

a user interface (UI) taxonomy that is an abstraction of a class of UIs; and

a UI generation module configured to retrieve first metadata from the UI taxonomy and second metadata that defines the service, wherein the UI generation module generates a UI for the application by merging the first and second metadata.

13. The computer system of claim 12, further comprising (1) an enterprise services UI layer, a UI platform layer and a virtualization layer, wherein the UI generation module retrieves the first and second metadata from the UI platform layer.

14. The computer system of claim 12, wherein the service is comprised of a web service and a UI service.

15. The computer system of claim 14, wherein the UI service defines a look-and-feel aspect of the web service.

16. The computer system of claim 14, wherein the web service is provided from a backend layer, and wherein the computer system further comprises an intermediate platform that implements the UI service for use by the application in a composite applications layer.

17. The computer system of claim 16, wherein several web services are provided from the backend layer, and wherein the intermediate platform includes an integration platform that implements the UI service for the several web services.

18. The computer system of claim 12, further comprising a UI services creation component that, when the service does not expose the second metadata, creates the second metadata using the service, wherein the second metadata can be retrieved upon creation.

19. The computer system of claim 12, wherein the UI taxonomy is configured such that the class of UIs is consistent with a UI layout and a UI principle included in the UI taxonomy.

20. The computer system of claim 19, wherein the UI taxonomy is further configured such that the class of UIs is consistent also with a UI environment included in the UI taxonomy.
