Method and system for republishing mobile content
View Patent ↗A system and method is provided for republishing content for a wireless device. In the wireless device, this may comprise: receiving a content manifest associated with a new content, the content manifest providing information about the new content; identifying any changes to existing content stored in the device, based on the information in the content manifest; retrieving updates in the new content corresponding to the changes; and storing the updates.
1. An electronic device comprising:
a communications subsystem for communicating with a communications network, the communications network including a content server configurable for delivering content to the electronic device; and
a storage device;
at least one processor configured to cause the electronic device to:
receive a content manifest associated with a content set comprising at least one content item, the content manifest including information for identifying each of the at least one content items, and information for retrieving each of the at least one content items;
identify any changes to existing content stored in the storage device based on the information in the content manifest;
retrieve updates for the content set corresponding to the changes; and
store the updates in the storage device.
2. The electronic device of claim 1 , wherein the content manifest has a verification piece for verifying the associated content set, and identifying any changes to the existing content comprises:
comparing the verification piece with information associated with the existing content in the storage device.
3. The electronic device of claim 2 wherein the verification piece is a checksum.
4. The electronic device of claim 1 wherein the content set comprises the updates corresponding to the changes to the existing content, and old content that is unchanged from the existing content, and wherein only the updates are retrieved.
5. The electronic device of claim 1 wherein the content manifest is received in the absence of any request for the content manifest from the electronic device.
6. The electronic device of claim 1 , wherein the processor is configured by at least one of a listener module, an email handler module, and a delivery manager module.
7. The electronic device of claim 1 , wherein the processor is configured to automatically retrieve the content manifest based on instructions received in an email.
8. The electronic device of claim 1 , wherein the processor is configured to send, to the content server, a request including information identifying the updates.
9. A method for updating content at an electronic device, the method comprising:
receiving, at the electronic device, a content manifest associated with a content set comprising at least one content item, the content manifest including information for identifying each of the at least one items, and information for retrieving each of the at least one items;
identifying, at the electronic device, any changes to existing content stored at the electronic device based on the information in the content manifest;
retrieving, from a content server, updates for the content set corresponding to the changes; and
storing the updates at the electronic device.
10. The method of claim 9 , wherein the content manifest has a verification piece for verifying the content set and identifying any changes to the existing content comprises:
comparing the verification piece with information associated with the existing content at the electronic device.
11. The method of claim 10 wherein the verification piece is a checksum.
12. The method of claim 9 wherein the content set comprises the updates corresponding to the changes to the existing content, and old content that is unchanged from the existing content, and wherein only the updates are retrieved.
13. The method of claim 9 wherein the content manifest is received in the absence of any request for the content manifest from the electronic device.
14. The method of claim 9 , wherein receiving the content manifest comprises: automatically retrieving the content manifest based on instructions received in an email.
15. The method of claim 9 , comprising sending, to the content server, a request including information identifying the updates.
16. A server comprising:
at least one processor configured for:
sending, to an electronic device, a content manifest associated with a content set comprising at least one content item, the content manifest including information for identifying each of the at least one items, and information for retrieving each of the at least one items; and
in response to a request, from the electronic device, identifying a subset of the content set, sending the subset to the electronic device;
wherein the content manifest includes information for identifying any changes to existing content at the electronic device.
17. The server of claim 16 , wherein the content manifest has a verification piece for verifying the associated content set.
18. The server of claim 17 wherein the verification piece is a checksum.
19. The server of claim 16 wherein the content manifest is sent in the absence of any request for the content manifest from the electronic device.
20. The server of claim 16 , wherein the processor is configured to send an email to the electronic device, the email including instructions which cause the electronic device to automatically retrieve the content manifest.
