Abstract

A data transmission system is disclosed which optimizes transfer and updates of information between systems by providing difference information between the systems. The system transmits data packages having instructions for manipulating user data. The data packages include a header identifying the respective packages, as well as transaction objects for effecting a change to user data on a device having object instructions.

Claims

1. A data package containing instructions for manipulating user data, comprising:

a header identifying the data package and containing information on content in the data package;

transaction objects operable to effect a change to user data on a device including object operation instructions.

2. The data package of claim 1 wherein each transaction object includes a content object which comprises binary data.

3. The data package of claim 2 wherein the binary data is raw data.

4. The data package of claim 2 wherein the binary data is binary difference data.

5. The data package of claim 1 wherein each transaction object includes a content object which comprises structured data.

6. The data package of claim 5 wherein the structured data includes a transaction header, an information list and a transaction list.

7. The data package of claim 6 wherein the transaction header comprises a transaction identifier, a data package identifier and a data package version.

8. The data package of claim 6 wherein the information list includes field identification information.

9. The data package of claim 6 wherein the information list comprises an operation, item information and field identification information.

10. The data package of claim 9 wherein the operation comprises one selected from the set of:

none, add, delete, change, move, rename, or force change without conflict.

11. The data package of claim 8 wherein the field identification information comprises a field tag and field data.

12. The data package of claim 1 wherein the header includes information on a synchronization agent which generated the data.

13. The data package of claim 1 wherein the header includes content type information.

14. The data package of claim 1 wherein the header includes device type information.

15. The data package of claim 1 wherein the header includes data size information.

16. The data package of claim 1 wherein said transaction object comprises an application object including information on the type of application from which the content originates.

17. The data package of claim 5 wherein said transaction object comprises a device object including information on the origin type of device.

18. The data package of claim 5 wherein said transaction object comprises a network object identifying information as coming from a particular user.

19. The data package of claim 1 wherein said transaction object is one of an object hierarchy which includes an account object, an device object, a data class object, a provider object, a data store object, an item list object and a field list object.

20. The data package of claim 16 wherein each transaction object is identified with a unique tag.

21. The data package of claim 1 wherein the data package is encrypted.

22. The data package of claim 1 wherein the data package is compressed.

23. The data package of claim 1 wherein the data package is encrypted and compressed.

51. The transaction object of claim 1 wherein including a tag representing actual content objects.

24. Code for instructing a software agent to alter data in a data structure, comprising:

a code header including information on the code;

at least one data object including content data from a user data store; and

a transaction object including instructions for operations on the at least one data object.

25. The code of claim 24 wherein the code header includes a package ID and a package version.

26. The code of claim 25 further including an encryption header.

27. The code of claim 25 further including a compression header.

28. The code of claim 24 wherein the data object comprises raw binary data.

29. The code of claim 24 wherein the data object comprises binary change data.

30. The code of claim 24 wherein the data object comprises structured application data.

31. The code of claim 30 wherein the transaction object comprises an operation, item information and a field list.

32. The code of claim 31 wherein the field list comprises a filed tag and field data.

33. The code of claim 31 wherein the item information includes an item type, an item flag, an entry id, and a parent entry id.

34. A structured transaction data package comprising:

a data package identifier;

a listing of fields addressed in the transaction; and

at least one operation associated with an item and a field.

35. The structured transaction data package of claim 34 wherein the field list comprises a filed tag and field data.

36. The structured transaction data package of claim 35 wherein the field data comprises a field data type and field data.

37. The structured transaction data package of claim 34 wherein the item information includes an item type, an item flag, an entry id, and a parent entry id.

38. The structured transaction data package of claim 34 wherein said item includes an item type, an entry id, and a parent entry id.

39. The structured transaction data package of claim 34 wherein the entry id is a static universally unique identifier.

40. The structured transaction data package of claim 34 wherein the entry id is a dynamic universally unique identifier.

41. A data file including code for instructing a processing device to change data on a user device, comprising:

a unique file identifier;

at least one association to a transaction content object; and

code instructing an agent having access to the user device to update the data on the device with the content object.

42. The data file of claim 41 wherein the association comprises a tag representing the actual content objects.

43. The data file of claim 41 wherein the transaction content object includes a user object.

44. The data file of claim 41 wherein the transaction content object includes a device object.

45. The data file of claim 41 wherein the transaction content object includes an application object.

46. The data file of claim 41 wherein the transaction content object includes a folder object.

47. The data file of claim 41 wherein the transaction content object includes an item object.

48. The data file of claim 41 wherein the transaction content object includes an item field object.

49. The data file of claim 47 wherein the item object includes a binary delta.

50. The data file of claim 47 wherein the item object includes a record delta.
