Abstract

A system for creating a sync group in a distributed system may include an offline electronic device having a short range communication transmitter and a storage service, and a computer-readable storage medium comprising one or more programming instructions. The system may receive a request from an application to create a sync group, and verify that the application has read access to the storage service. In response to verifying that the application has read access to the storage service, the system may create the sync group by receiving an indication of one or more objects stored in the storage service that are to be shared, identifying one or more members of the sync group, and assigning one or more permissions to the one or more members that are identified. The system may synchronize access to the objects among the electronic device and one or more member electronic devices.

First claim

What is claimed is:

1. A method of creating a sync group, the method comprising:
receiving, by a storage service associated with a first electronic device, a request from an application to create a sync group, wherein the first electronic device is offline;
verifying, by the storage service, that the application has read access to the storage service;
in response to verifying that the application has read access to the storage service, creating locally within the storage service the sync group by:
receiving an indication of one or more objects stored in the storage service that are to be shared,
identifying one or more user members of the sync group with whom to share the one or more objects, each user member associated with one or more member electronic devices, and
assigning one or more permissions of a set of possible permissions to the one or more member electronic devices associated with the user members that are identified, the set of possible permissions including read access, write access, and administrative access;

synchronizing access to the objects among the offline first electronic device and the one or more member electronic devices associated with the one or more user members such that the objects are accessible via each of the member electronic devices when the member electronic devices are within range of a short range communication transmitter of the offline first electronic device, wherein access to the objects by the member electronic devices is synchronized in accordance with the one or more permissions that are assigned and in accordance with one or more conflict resolution policies;
detecting, by the first electronic device, a network connection that facilitates communications with a sync group server; and
sending, by the first electronic device via the detected network connection, information identifying the sync group to the sync group server for continued synchronization through the sync group server when the one or more member electronic devices are no longer within range of the short range communication transmitter of the first electronic device.

2. The method of claim 1 , further comprising:
assigning a unique name to the sync group; and
publishing the unique name to a listing that is accessible by the member electronic devices.

3. The method of claim 1 , wherein each of the member electronic devices is offline.

4. The method of claim 1 , further comprising assigning a unique name to the sync group.

5. The method of claim 1 , wherein assigning the one or more permissions comprises generating an access control list (ACL) that indicates which of the member electronic devices are permitted to access the objects.

6. A method of creating a sync group, the method comprising:
receiving, by a storage service associated with a first electronic device, a request from an application to create a sync group;
verifying, by the storage service, that the application has read access to the storage service;
in response to verifying that the application has read access to the storage service, creating locally within the storage service the sync group by:
receiving an indication of one or more objects stored in the storage service that are to be shared,
identifying one or more user members of the sync group with whom to share the one or more objects, each user member associated with one or more member electronic devices, and
assigning one or more permissions of a set of possible permissions to the one or more member electronic devices associated with the user members that are identified, the set of possible permissions including read access, write access, and administrative access, identifying a sync group server associated with the sync group;

detecting a network connection that facilitates communications with the sync group server;
sending a notification to the sync group server using the detected network connection, the notification notifying the sync group server that the sync group has been created locally within the storage service; and
synchronizing access to the objects among the first electronic device and one or more member electronic devices associated with the one or more members such that the objects are accessible via each of the member electronic devices at any time regardless of whether the first electronic device is executing the application at that time, wherein access to the objects by the member electronic devices is synchronized in accordance with the one or more permissions that are assigned and further in accordance with one or more conflict resolution policies.

7. The method of claim 6 , further comprising:
assigning a unique name to the sync group; and
publishing the unique name to a listing that is accessible by the member electronic devices.

8. The method of claim 6 , further comprising assigning a unique name to the sync group.

9. The method of claim 6 , wherein assigning one or more permissions comprises generating an access control list (ACL) that indicates which of the member electronic devices are permitted to access the objects.

10. The method of claim 6 , wherein sending a notification to the sync group server comprises communicating with the sync group server using one or more remote procedure calls.

11. A system for creating a sync group in a distributed system, the system comprising:
an electronic device comprising a short range communication transmitter and a storage service, wherein the electronic device is offline; and
a computer-readable storage medium comprising one or more programming instructions that, when executed, cause the offline, electronic device to:
receive a request from an application to create a sync group,
verify that the application has read access to the storage service,
in response to verifying that the application has read access to the storage service, create locally within the storage service the sync group by:
receiving an indication of one or more objects stored in the storage service that are to be shared,
identifying one or more user members of the sync group, each user member associated with one or more member electronic devices, and
assigning one or more permissions of a set of possible permissions to the one or more member electronic devices associated with the user members that are identified, the set of possible permissions including read access, write access, and administrative access;

synchronizing access to the objects among the offline, electronic device and the one or more member electronic devices associated with the one or more user members such that the objects are accessible via each of the member electronic devices when the member electronic devices are within range of the transmitter, wherein access to the objects by the member electronic devices is synchronized in accordance with the one or more permissions that are assigned and further in accordance with one or more conflict resolution policies;
detecting, by the first electronic device, a network connection that facilitates communications with a sync group server; and
sending, by the first electronic device via the detected network connection, information identifying the sync group to the sync group server for continued synchronization through the sync group server when the one or more member electronic devices are no longer within range of the short range communication transmitter of the first electronic device.

12. The system of claim 11 , wherein the computer-readable storage medium further comprises one or more instructions that, when executed, cause the offline, electronic device to:
assign a unique name to the sync group so that the unique name includes a name of a sync group server; and
