Abstract

Methods and apparatus are disclosed for notifying one or more users of information. A list of one or more subscribable objects is provided to one or more of the users; a subscription request is received from one or more of the users based on at least one of the subscribable objects; and a determination is made as to whether a user providing a subscription request has a privilege to subscribe to the subscribable object. The list optionally comprises only subscribable objects that the user is privileged to subscribe to. Once one or more users are identified that entered a subscription that matches the notification information, a determination is made as to whether the identified users have appropriate privileges associated with the information before a notification containing the information is sent to the identified users. The appropriate privileges comprise, for example, a privilege to subscribe to an object associated with the information and a privilege to notify any subscribers and delegates associated with the notification.

Claims

1. A method for notifying one or more users of information, comprising:

providing a list of one or more subscribable objects to one or more of said users, wherein said step of providing a list further comprises the step of listing only subscribable objects that said user is privileged to subscribe to, wherein each subscribable object comprises an attribute-value pair and corresponds to one of a plurality of topics of interest that said user can subscribe to;

receiving a subscription request from one or more of said users based on at least one of said subscribable objects; and

determining whether a user providing a subscription request has a privilege to subscribe to said subscribable object.

2. The method of claim 1, wherein said subscription request comprises a subscription for at least one additional person.

3. The method of claim 1, further comprising the step of importing one or more subscriptions from another user.

4. The method of claim 1, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to any subscribable object.

5. The method of claim 1, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to a specific subscribable object.

6. The method of claim 1, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to a specific subscribable object owned by a specific application.

7. The method of claim 1, wherein said subscription request comprises a subscription for information that does not have any subscribers.

8. The method of claim 1, wherein said subscription request comprises a subscription for notifications that do not receive any responses.

9. An apparatus for notifying one or more users of information, the apparatus comprising:

a memory; and

at least one processor, coupled to the memory, operative to;

provide a list of one or more subscribable objects to one or more of said users, wherein said processor is further configured to list only subscribable objects that said user is privileged to subscribe to, wherein each subscribable object comprises an attribute-value pair and corresponds to one of a plurality of topics of interest that said user can subscribe to;

receive a subscription request from one or more of said users based on at least one of said subscribable objects; and

determine whether a user providing a subscription request has a privilege to subscribe to said subscribable object.

10. The apparatus of claim 9, wherein said subscription request comprises a subscription for at least one additional person.

11. The apparatus of claim 9, wherein said processor is further configured to import one or more subscriptions from another user.

12. The apparatus of claim 9, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to any subscribable object.

13. The apparatus of claim 9, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to a specific subscribable object.

14. The apparatus of claim 9, wherein said privilege to subscribe to said subscribable object comprises a privilege to create a subscription to a specific subscribable object owned by a specific application.

15. The apparatus of claim 9, wherein said subscription request comprises a subscription for information that does not have any subscribers.

16. The apparatus of claim 9, wherein said subscription request comprises a subscription for notifications that do not receive any responses.

17. An article of manufacture for notifying one or more users of information, comprising a machine readable medium containing one or more programs which when executed implement the steps of,

providing a list of one or more subscribable objects to one or more of said users, wherein said processor is further configured to list only subscribable objects that said user is privileged to subscribe to, wherein each subscribable object comprises an attribute-value pair and corresponds to one of a plurality of topics of interest that said user can subscribe to;

receiving a subscription request from one or more of said users based on at least one of said subscribable objects; and

determining whether a user providing a subscription request has a privilege to subscribe to said subscribable object.

18. The article of manufacture of claim 17, wherein said subscription request comprises a subscription for at least one additional person.

19. The article of manufacture of claim 17, further comprising the step of importing one or more subscriptions from another user.

20. The article of manufacture of claim 17, wherein said privilege to subscribe to said subscribable object comprises one or more of a privilege to create a subscription to any subscribable object;
