Subscription and notification service

1. An apparatus comprising:

a processor; and

a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:

receiving a subscription request from a subscriber device to a first resource, wherein the first resource is a uniquely addressable element in a Resource Oriented Architecture (ROA) having a representation that can be manipulated via RESTful methods;

detecting, based on receiving the subscription request, an event notification criteria has been met for the first resource, wherein the event notification criteria defines when a notification event is to be generated;

detecting, based on receiving the subscription request, instruction which statistical information about the notification events should be calculated and maintained;

generating an event notification for the first resource;

transmitting a notification message to a notification target;

calculating and recording notification statistical information based on the detected instruction;

receiving a retrieval request to retrieve the notification statistical information; and

based on the retrieval request, sending a response, wherein the response comprises the recorded notification statistical information.

2. The apparatus of claim 1 , wherein the subscription request comprises a time window of calculating the notification statistical information.

3. The apparatus of claim 1 , wherein the subscription request comprises a list of notification targets whose notification statistics is to be calculated.

4. The apparatus of claim 1 , wherein the statistical information comprises a number of successfully received notifications by a notification target.

5. The apparatus of claim 4 , wherein the statistical information further comprises a number of unsuccessful notifications sent to a notification target.

6. The apparatus of claim 1 , the operations further comprising:

obtaining a request from the subscriber to adjust notification targets; and

sending a response to the subscriber that comprises the result of the adjustment.

7. The apparatus of claim 1 , wherein the statistical information comprises a number of successfully received notifications by a notification target in the ROA.

8. The apparatus of claim 7 , wherein the statistical information further comprises a number of unsuccessful notifications sent to a notification target in the ROA.

9. A method comprising:

receiving a subscription request from a subscriber device to a first resource, wherein the first resource is a uniquely addressable element in a Resource Oriented Architecture (ROA) having a representation that can be manipulated via RESTful methods;

detecting, upon receiving the subscription request, an event notification criteria has been met for the first resource, wherein the event notification criteria defines when a notification event is to be generated;

detecting, upon receiving the subscription request, instruction which statistical information about the notification events should be calculated and maintained;

generating an event notification for the first resource;

transmitting a notification message to a notification target;

calculating and recording notification statistical information based on the detected instruction;

receiving a retrieval request to retrieve the notification statistical information; and

based on the retrieval request, sending a response, wherein the response comprises the recorded notification statistical information.

10. The method of claim 9 , wherein the statistical information comprises a number of successfully received notifications by a notification target in the ROA.

11. The method of claim 10 , wherein the statistical information further comprises a number of unsuccessful notifications sent to a notification target in the ROA.

12. The method of claim 11 , the method further comprising receiving a request to stop recording notifications or change notifications recording settings.

13. The method of claim 11 , the method further comprising authorizing if one of the subscriber device, the notification target and other entities have access to recorded notifications according to access control policies.

14. A method comprising:

sending a subscription request for a first resource, the first resource being a uniquely addressable element in a Resource Oriented Architecture (ROA) having a representation that can be manipulated via RESTful methods, wherein the subscription request comprises:

an event notification criteria that defines when a subscription and a notification service is to generate notification events, and

instructions on which statistical information about the notification events should be calculated and maintained;

sending a retrieval request to retrieve the notification statistical information; and

receiving a response comprising the requested notification statistical information.

15. The method of claim 14 , the method further comprising:

based on the received notification statistical information, determining an adjustment to notification targets; and

sending a request to adjust notification targets.

16. The method of claim 14 , wherein the statistical information comprises a number of successfully received notifications by a notification target in the ROA.

17. The method of claim 16 , wherein the statistical information further comprises a number of unsuccessful notifications sent to a notification target in the ROA.

18. The method of claim 17 , the method further comprising:

receiving a request to stop recording notifications or change notifications recording settings.

19. The method of claim 17 , the method further comprising:

authorizing if one of the subscriber device, the notification target and other entities have access to recorded notifications according to access control policies.
