Abstract

A method of sending data held on a primary processing apparatus (2) to one or more data receiving devices is disclosed. On receiving a request for data, the method comprises arranging the data on a processing apparatus in two or more information levels such that a predetermined subset of the data comprising data at one of the information levels is sent to a particular device. Each level may compare data which is appropriate to the receiving device, for example, so that a shorter version of a text at one level is sent to a requesting mobile phone (26) while a full version of the text at another level is sent to a personal computer display (30).

11. A method according to claim 7 wherein transforming said data held on said primary processing apparatus allows said predetermined subset of said data held on said primary processing apparatus to be selected to be sent to said particular data-receiving device.

12. A method according to claim 7 wherein transforming said data held on said primary processing apparatus allows the presentation to be specified for each subset of said data held on said primary processing apparatus.

13. A method according to claim 1 which comprises associating said data-receiving devices capable of communicating with said primary processing device with a predetermined one of said information levels.

14. A method according to claim 1 wherein said data comprises at least one data sub-item and said method comprises marking each of said data sub items to indicate the information level to which said data sub item belongs.

15. A method according to claim 1 wherein said data comprises at least one data sub-item and said method comprises grouping said data sub-items and further marking each group as belonging to an information level.

16. A method according to claim 1 wherein said primary processing apparatus is provided with data and generates said information levels from the data with which it is provided.

17. A method according to claim 1 wherein said primary processing apparatus is provided with a set of tools to enable a user to generate said information levels and said method comprises said user generating said information levels using said set of tools.

18. A method according to claim 1 comprising determining the capability of said data receiving device to receive data before said data held on said primary processing apparatus is sent.

19. A method according to claim 18 comprising only sending information levels that said data receiving device that is to be sent data is capable of receiving once the said capability has been determined.20.

20. A method according to claim 1 comprising arranging said information levels in a hierarchical structure according to the level of detail of their content wherein the highest information level contains the most detail and the lowest information level contains the least detail.

21. A method according to claim 20 wherein said primary processing apparatus is capable of receiving an error message, said data-receiving device is capable of sending an error message and said method comprises the following steps;

i) causing said primary processing apparatus to send said data at a first information level;

ii) on receipt of a said error message from said data-receiving device to send said data at a further, lower, information level iii) repeating steps i and ii until said information has been correctly sent to said data receiving device.

22. A method according to claim 20 wherein said primary processing apparatus is capable of receiving an error message, said data-receiving device is capable of sending an error message and said method comprises the following steps:

i) causing said primary processing apparatus to send said data at a first information level;

ii) then to send said data at a second information level higher than the first;

iii) to repeat steps i and ii until an error message is returned to said primary processing apparatus from said data receiving device.

23. A method according to claim 19 comprising arranging said data held on said primary processing apparatus such that to send data at a particular one of said information levels requires data in the information levels below said particular information level to be sent.

25. A computer readable medium holding instructions capable of causing a computer to perform the method of claim 1 where loaded thereonto.

27. A data-receiving device arranged to be controlled by a program, said program being tailored to facilitate communication with said primary processing apparatus of claim 24.
