Abstract

A method (100), apparatus (200) and computer program product for editing an electronic document is disclosed. Editorial modifications that a first collaborator has made to the document are published. Receipt of the modifications is acknowledged by one or more other collaborators and the published modifications are merged with any local modifications to produce a merged version of said modifications. The merged modifications are applied to the document to produce an edited version of the document including the editorial modifications. The edited version containing data incorporated therein indicating acknowledgment of the editorial modifications by one or more of the collaborators.

Claims

1. A method of editing an electronic document created by a first one of a plurality of collaborators connected to a network, said method comprising the steps of:

transmitting a copy of said electronic document over said network to at least each of a second and a third one of said plurality of collaborators;

receiving from said second and third collaborators, via said network, a first patch from the second collaborator and a second patch from the third collaborator, the first and second patches representing editorial modifications that said second and third collaborators have made to the copies of said electronic document transmitted to said second and third collaborators, wherein the patches are transmitted from said second and third collaborators to said first collaborator separately from each other and from any copy of said electronic document;

transmitting, from the first to the second collaborator, an acknowledge receipt for said first patch, and from the first to the third collaborator, an acknowledge receipt for said second patch, the copies of the electronic document transmitted to said second and third collaborators being updated upon receipt of the acknowledge receipts;

merging the editorial modification represented by said first and second patches with any local modifications, using said patches, to produce a merged representation of modifications to be made to said electronic document, wherein said merged representation is dependant on whether one or more of said plurality of collaborators was offline at a time when said editorial modifications of said local modification were made; and

applying the modifications represented by said merged representation to said electronic document to produce an edited version of said electronic document, the edited version containing data incorporated therein indicating acknowledgment of said modifications made by said second and third collaborators.

2. A method according to claim 1, further comprising the step of updating the data incorporated within the edited version of the document to indicate acknowledgment of said published editorial modifications by the other collaborators.

3. A method according to claim 1, wherein the data identifies the version of the document.

4. A method according to claim 1, wherein the data comprises a universally-unique identifier.

5. A method according to claim 1, wherein the modifications represented by said merged representation are applied depending on whether said second collaborator was active when the document was last modified by any one of the collaborators.

6. A method according to claim 1, further comprising the step of determining a component of the modifications to be made to said document using a calculated weighted arithmetic mean.

7. A method according to claim 1, further comprising the step of electing a value for one or more components of said merged modifications to be made to said document.

8. A method according to claim 1, wherein any one or more of the steps of said method are performed independently by two or more computers connected over said network.

9. A method according to claim 1, wherein the edited version of the document is transmitted over said network.

10. The method according to claim 1, further comprising the steps of:

the third collaborator receiving, from the second collaborator, the first patch, wherein the first patch is transmitted from the second collaborator to the third collaborator separately from any copy of said electronic document;

merging the editorial modifications represented by said first patch with the second patch, using said patches, to produce a merged representation of modifications to be made to said copy of the electronic document transmitted to the third collaborator; and

applying the modifications represented by said merged representation to said copy of the electronic document transmitted to the third collaborator to produce an edited version of said electronic document.

11. A method of synchronizing versions of an electronic document modified collaboratively over a network, said method comprising the steps of:

determining a most recent version of said electronic document that is stored locally on the network by analyzing data incorporated within one or more locally stored versions of said electronic document, the data indicating acknowledgment of a particular version of said electronic document by at least a first one of a plurality of collaborators;

requesting a first and second patch representing editorial modifications made to the most recent version of said electronic document by a second and third one of the collaborators at a remote location of the network;

receiving from said second and third collaborators, via said network, said first patch from the second collaborator and said second patch from the third collaborator, the first and second patches representing said editorial modifications that said second and third collaborators have made to said most recent version of said electronic document, wherein the patches are transmitted from said second and third collaborators to said first collaborator separately from each other and from any copy of said electronic document;

transmitting, from the first to the second collaborator, an acknowledge receipt for said first patch, and from the first to the third collaborator, an acknowledge receipt for said second patch, copies of the electronic document stored with said second and third collaborator being updated upon receipt of the acknowledge receipts; and

applying the modifications represented by said received patches to the locally stored most recent version of said electronic document to produce a synchronized version of said electronic document.

12. A method according to claim 11, further comprising the step of merging the editorial modifications represented by said received first and second patches with any local modifications using said received patches to produce a merged representation of modifications to be made to said electronic document.

13. A method according to claim 12, further comprising the step of applying the modifications represented by said merged representation to said electronic document to produce an edited version of said electronic document.

14. A method according to claim 13, further comprising the step of updating data incorporated within the edited version of said electronic document to indicate acknowledgment of receipt of said received patches made by said second and third collaborators.

15. A method according to claim 11, wherein the data identifies the version of a particular electronic document.

16. A method according to claim 11, wherein the data comprises a universally-unique identifier.
