Method and System For Providing A Subscription To A Tuple Based On A Variable Identifier

A system for providing a subscription to a tuple, the system comprising system components including:

• a subscription profiler component configured to receive subscription information identifying a subscriber and identifying a tuple identifier expression including a variable identifying a stored data entity;
• a service agent component configured to generate a message identifying the tuple identifier expression and the subscriber;
• and
• a protocol service agent component configured to send the message to a publish/subscribe service node configured to host a service for establishing a subscription for the identified subscriber to receive a notification including a current value of a tuple identified based on an evaluation of the tuple identifier expression,
• wherein at least one of the system components includes at least one electronic hardware component.

A system for providing a subscription to a tuple, the system comprising:

• means for receiving subscription information identifying a subscriber and identifying a tuple identifier expression including a variable identifying a stored data entity;
• means for determining a first tuple identifier by evaluating the tuple identifer expression with the variable set to a first current value stored in the data entity;
• means for establishing a subscription for the identified subscriber to a first tuple identified by the determined first tuple identifier;
• and
• means for sending a first notification message including tuple information from the first tuple to the identified subscriber,
• wherein at least one of the means includes at least one electronic hardware component.

A method for providing a subscription to a tuple, the method comprising:

• receiving subscription information identifying a subscriber and identifying a tuple identifier expression including a variable identifying a stored data entity;
• generating by a service agent representing a principal a message identifying the tuple identifier expression and the subscriber;
• and
• sending by a protocol service agent the message to a publish/subscribe service node configured to host a service for establishing a subscription for the identified subscriber to receive a notification including a current value of a tuple identified based on an evaluation of the tuple identifier expression,
• wherein at least one of the preceding actions is performed on at least one electronic hardware component.

A computer readable medium storing a computer program, executable by a machine, for providing a subscription to a tuple, the computer program comprising executable instructions for:

• receiving subscription information identifying a subscriber and identifying a tuple identifier expression including a variable identifying a stored data entity;
• determining a first tuple identifier by evaluating the tuple identifer expression with the variable set to a first current value stored in the data entity;
• establishing a subscription for the identified subscriber to a first tuple identified by the determined first tuple identifier;
• and
• sending a first notification message including tuple information from the first tuple to the identified subscriber.
