1. A method of diagnosing faults in performance of providing content to display devices and displaying the content provided, the method comprising:

providing to a plurality of entities sufficient information concerning (a) at least one device and (b) at least one content item, such that each individual entity is able to arbitrate concerning a performance of said device and said content, on the basis of device information comprising at least one device profile describing content delivery capabilities of said at least one device and content information comprising at least one capability class description, which describes capabilities of a class of devices for displaying a particular content version; and

mapping said content item based on said capability class description to obtain mapped content,

wherein the arbitration comprises testing that the device may correctly display the mapped content.

2. A process for enabling enterprises to work together to establish systems which operate correctly wherein components of the system use a semantic web for negotiating capabilities, said process comprising:

receiving at least one content item;

receiving a capability class description describing capabilities of a class of devices for displaying a particular content version;

receiving a mapping of the content to the device capability class;

applying said mapping to said content, to determine whether said mapping correctly maps said content to said capability class descriptions;

testing said mapped content against a device to determine whether said device may correctly display said mapped content;

and generating a message depending upon a result of said test.

3. The process as claimed in claim 2, further comprising:

depending upon a result of said test;

generating a message indicating that said mapped content has failed to display on said device.

4. The method as claimed in claim 2, further comprising:

generating a diagnostic message describing whether a fault is attributable to at least one of the following;

a fault in a mapping of said content to a said device capability class;

a fault in a device capability class description;

a fault in a devices conformity to said device capability class description.

5. A system for enabling enterprises to work together for establishing systems which operate correctly, wherein components of said system are operable for negotiating capabilities of said system using a semantic web structure, said system comprising:

at least one openly available capability class description which describes capabilities of a class of devices for displaying a particular content version; and

a test component capable of testing whether a mapped content item may be correctly displayed on a device, and whether said device conforms with said device capability class description.

6. The system as claimed in claim 5, wherein said test component comprises a test program operable by a device manufacturer.

7. The system as claimed in claim 5, wherein said test component comprises a test program operable by a content provider enterprise.

8. A test method for testing that content is displayable by at least one device, said method comprising:

establishing a device capability description describing capabilities of a device class for displaying a particular content version, of which said device is a member;

establishing a mapping of said content to said capability class description;

mapping said content to said device capability using said mapping data; and

testing said device to determine whether said mapped content may be correctly displayed on said device and to establish that said device conforms to said capability class description; and

generating a message depending upon a result of said test.

9. The method as claimed in claim 8, comprising:

testing said mapped content on a device of a type falling within said capability class description.

10. The method as claimed in claim 8, comprising:

testing said mapped content on a device emulator of a type falling within said capability class description.

11. The method as claimed in claim 8, wherein:

if, as a result of said testing, said mapped content may not be correctly displayed on said device, a fault report is generated.

12. The method as claimed in claim 8, wherein:

if, as a result of said testing, said mapped content may not be correctly displayed on said device may not be correctly displayed on said device, a fault report is generated; and

said fault report is made available to a community of enterprises over a communication network.

13. The method as claimed in claim 8, wherein said mapping data is made available to a community of enterprises over a communications network.

14. The method as claimed in claim 8, wherein said capability class description is made available to a community of enterprises, over a communications network.

15. A test method for verifying whether a content item is correctly displayable on a device, said method comprising;

providing a device capability class description describing a set of capabilities for displaying a particular content version of a class of devices to which a said device is designed to belong to;

providing a mapping of a content item to said device capability class description;

testing whether said mapped content displays correctly on a device emulator; and

generating a message depending upon a result of said test.

16. A system for enabling design of display devices to display content items, said system comprising:

at least one device profile server computer entity, said device profile server capable of supplying a capability class description describing capabilities of a class of devices for displaying a particular content version;

at least one content provider server computer entity capable of serving at least one content item for display on a said display device; and

at least one test component, said test component operable for;

mapping said content to a said capability class description using a said mapping data; and

testing said mapped content on a test device to determine whether said mapped content may be correctly displayed on said display device; and

wherein said test component is operable for generating a test result message depending upon a result of said test.

17. The system as claimed in claim 16, wherein said test component comprises a device emulator application.

18. The system as claimed in claim 16 wherein said test component is operable for generating a test result message indicating whether said mapped content correctly displays on said test device or not.

19. The method as claimed in claim 16, wherein said content item comprises a plurality of content components;

and

said mapping data comprises, for each said content component, a mapping between said content component and a description of a capability of class devices comprising at least one device.

20. A computer readable medium containing program instructions for controlling a computer entity for verifying that a content item can be correctly displayed on a display device, said computer readable medium, when executed on a computer, performing instructions for:

receiving a capability class description describing capabilities of a class of devices for displaying a particular content version;

receiving a said content component;

receiving a mapping data for mapping said content item to a device within said capability class description;

mapping said content to said capability class using said mapping data;

displaying said mapped content on said test device; and

determining whether or not said mapped content displays correctly on said test device.

21. The computer readable medium as claimed in claim 20, further performing instructions for:

generating a fault report describing a fault in displaying content on said test device.

22. The computer readable medium instructions as claimed in claim 20, further performing instructions for:
