Abstract

A computer-implemented method is provided for managing and sharing picture files. In one embodiment of the present invention, the method comprises providing a server platform and providing a datastore on the server platform for maintaining full resolution copies of the files shared between a plurality of sharing clients. A synchronization engine is provided on the server platform and is configured to send real-time updates to a plurality of sharing clients when at least one of the sharing clients updates or changes one of said files. A web interface may also be provided that allows a user to access files in the datastore through the use of a web browser.

Claims

1. A method comprising:

determining an organization for a plurality of data objects synced between a first client device associated with a first user and a synchronization server, the organization being based on metadata associated with each data object of the plurality of data objects;

receiving, by the synchronization server, indicia that the first user has shared a data object from the plurality of data objects with a second user, the sharing of the data object including a grant of permission by the first user to the second user to modify metadata associated with the data object on a second client device associated with the second user;

in response to receiving the indicia, enabling the second user to modify the metadata associated with the data object on the second client device;

receiving a notification of a change to the metadata associated with the data object by the second user on the second client device;

determining, at the synchronization server, an updated organization for the plurality of data objects synced between the first client device and the synchronization server based on the change to the metadata associated with the data object; and

propagating the updated organization for the plurality of data objects to the first client device associated with the first user.

2. The method of claim 1, wherein:

the data object is a photo album, and

the grant of permission by the first user to the second user to modify the metadata associated with the data object comprises permission to edit captions or people associated with photos in the photo album.

3. The method of claim 1, wherein receiving the notification of the change to the metadata comprises receiving the notification from a synchronization application, running on the second client device, for monitoring the plurality of data objects for changes and communicating the changes from the second client device to the synchronization server.

4. The method of claim 3, wherein the synchronization application, running on the first client device, enables the first user to manage sharing of the data object with different groups of users at different times based on a multi-phase commit process.

5. The method of claim 3, wherein the synchronization application comprises a contact list for enabling sharing of the data object across each of a plurality of client devices.

6. The method of claim 1, further comprising providing real-time updates for the data object.

7. The method of claim 1, wherein the data object is a file.

8. The method of claim 7, wherein the file is one of a photo, an audio file, a video file, or a document.

9. The method of claim 8, wherein the file is the photo and the metadata associated with the photo comprises one of location, people, or objects in the photo.

10. A non-transitory computer-readable storage medium comprising instructions that, when executed by at least one processor, cause a computing device to:

determine an organization for a plurality of data objects synced between a first client device associated with a first user and a synchronization server, the organization being based on metadata associated with each data object of the plurality of data objects;

receive indicia that the first user has shared a data object from the plurality of data objects with a second user, the sharing of the data object including a grant of permission by the first user to the second user to modify metadata associated with the data object on a second client device associated with the second user;

in response to receiving the indicia, enable the second user to modify the metadata associated with the data object on the second client device;

receive a notification of a change to the metadata associated with the data object by the second user on the second client device;

determine an updated organization for the plurality of data objects synced between the first client device and the synchronization server based on the change to the metadata associated with the data object; and

propagate the updated organization for the plurality of data objects to the first client device associated with the first user.

11. The non-transitory computer-readable storage medium of claim 10, wherein:

the data object is a photo album, and

the grant of permission by the first user to the second user to modify the metadata associated with the data object comprises permission to edit captions or people associated with photos in the photo album.

12. The non-transitory computer-readable storage medium of claim 10, wherein the instructions, when executed by the at least one processor, cause the computing device to receive the notification of the change to the metadata by receiving the notification from a synchronization application, running on the second client device, for monitoring the plurality of data objects for changes and communicating the changes from the second client device to the synchronization server.

13. The non-transitory computer-readable storage medium of claim 12, wherein the synchronization application, running on the first client device, enables the first user to manage sharing of the data object with different groups of users at different times based on a multi-phase commit process.

14. The non-transitory computer-readable storage medium of claim 12, wherein the synchronization application comprises a contact list for enabling sharing of the data object across each of a plurality of client devices.

15. The non-transitory computer-readable storage medium of claim 10, further comprising instructions that, when executed by the at least one processor, cause the computing device to provide real-time updates for the data object.

16. The non-transitory computer-readable storage medium of claim 10, wherein the data object is a file.

17. The non-transitory computer-readable storage medium of claim 16, wherein the file is one of a photo, an audio file, a video file, or a document.

18. The non-transitory computer-readable storage medium of claim 16, wherein the file is the photo and the metadata associated with the photo comprises one of location, people, or objects in the photo.

19. A system comprising:

at least one processor; and

at least one non-transitory computer readable storage medium comprising instructions that, when executed by the at least one processor, cause the system to;

determine an organization for a plurality of data objects synced between a first client device associated with a first user and a synchronization server, the organization being based on metadata associated with each data object of the plurality of data objects;

receive indicia that the first user has shared a data object from the plurality of data objects with a second user, the sharing of the data object including a grant of permission by the first user to the second user to modify metadata associated with the data object on a second client device associated with the second user;

in response to the receiving the indicia, enable the second user to modify the metadata associated with the data object on the second client device;

receive a notification of a change to the metadata associated with the data object by the second user on the second client device;

determine an updated organization for the plurality of data objects synced between the first client device and the synchronization server based on the change to the metadata associated with the data object; and

propagate the updated organization for the plurality of data objects to the first client device associated with the first user.

20. The system of claim 19, wherein:

the data object is a photo album, and

the grant of permission by the first user to the second user to modify the metadata associated with the data object comprises permission to edit captions or people associated with photos in the photo album.
