Abstract

A method for delivering published information associated with a tuple using a pub/sub communication protocol includes receiving partitioning information associated with the tuple and using the partitioning information to define a plurality of distinct tuple elements. Each distinct tuple element corresponds to a portion of the published information associated with the tuple. A series of notification messages is sent to a recipient client where each notification message is associated with one of the plurality of distinct tuple elements for providing each related portion of the published information to the recipient client.

Claims

receiving partitioning information associated with the tuple;

defining a plurality of distinct tuple elements each related to a portion of the published information associated with the tuple based on the received partitioning information; and

sending a series of notification messages to a recipient client, each notification message being associated with one of the plurality of distinct tuple elements for providing each related portion of the published information to the recipient client.

2. The method of claim 1 further comprising forming a notification message associated with one of the plurality of distinct tuple elements by including the portion of the published information related to the one distinct tuple element in the notification message.

3. The method of claim 1 further comprising forming a notification message associated with one of the plurality of distinct tuple elements by including an identifier that references the portion of the published information related to the one distinct tuple element in the notification message.

4. The method of claim 1 further comprising associating the plurality of distinct tuple elements with a subscription and wherein sending the series of notification messages is pursuant to the subscription.

5. The method of claim 1 wherein the partitioning information is provided by a publisher associated with the tuple and includes at least one of an order in which each of the notification messages in the series of notification messages is to be sent and an indication of how the plurality of distinct tuple elements is to be defined.

6. The method of claim 1 wherein the partitioning information is included in a subscription request to the tuple and includes at least one of:

an indication of how the plurality of distinct tuple elements is to be defined, an order in which each of the notification messages in the series of notification messages is to be sent, a time interval between the sending of each notification, a characteristic of a device to which the series of notification messages is to be sent, and information related to a subscriber to which the series of notification messages is to be sent.

7. The method of claim 1 further including:

in response to receiving a request from a subscriber to subscribe to the tuple, sending a form to the subscriber that allows the subscriber to provide the partitioning information.

8. The method of claim 1 further comprising:

receiving an update to the tuple from a publisher;

updating the tuple; and

sending the series of notification messages each associated with one of the plurality of distinct tuple elements for providing each corresponding portion of the published information to the recipient device.

9. The method of claim 8 wherein receiving the partitioning information, receiving the update, and sending the notifications is performed using a publish/subscribe communication protocol.

10. The method of claim 8 wherein at least one of the notification messages in the series of notification messages includes published information that has not been modified by the update to the tuple.

11. The method of claim 1 wherein the tuple comprises a set of tuple elements and wherein defining the plurality of distinct tuple elements includes:

selecting the plurality of distinct tuple elements from the set of tuple elements based on the partitioning information, wherein the selected plurality of distinct tuple elements is a subset of the set of tuple elements.

12. A method for receiving information associated with a tuple using a publish/subscribe communication protocol, the method comprising:
