12. A method for providing customized subscription information comprising:

receiving in a publisher service a notification of a subscription related to a resource;

creating a profile associated with the notification of the subscription, the profile created using a characteristic of the notification of the subscription;

using the profile to generate customized information related to the resource, the customized information based on the characteristic; and

sending the customized information to a publish/subscribe service for delivery to a subscriber associated with the subscription.

13. The method of claim 12 wherein a tuple is associated with the resource by the publish/subscribe service for providing the customized information.

14. The method of claim 13 wherein sending the customized information to a publish/subscribe service includes:

using a directed publish/notify command to allow the publish/subscribe service to deliver the customized information to the subscriber.

15. The method of claim 13 wherein the tuple is a custom tuple associated with the customized information and is created for the subscription, and the subscriber is on a subscriber list associated with the custom tuple, and wherein sending the customized information includes directing the publish/subscribe service to publish the customized information to the custom tuple.

16. The method of claim 12 wherein creating the profile includes at least one of:

identifying the customized information based on the characteristic of the notification of the subscription, defining a schema for presenting the customized information, identifying a triggering event, and defining where to send the customized information.

17. The method of claim 16 further comprising:

detecting an event related to the resource;

determining whether information related to the event should be published based on the profile for the subscription; and

generating the customized information according to the profile when the profile indicates the information related to the event is to be published.

18. A system for providing customized subscription data from a publisher to a subscriber, the system comprising:

a publish/subscribe service configured to receive from the subscriber a subscription request for a tuple, to create a first message related to the subscription request to be sent to the publisher, to receive from the publisher a second message induding customized information, wherein the customized information is based on a characteristic of the first message, to construct a notification including the customized information, and to send the notification including the customized information to the subscriber; and

a communications protocol stack component coupled to the publish/subscribe service configured to allow the publish/subscribe service to receive the subscription request and to send the notification including the customized information using a publish/subscribe protocol.

19. The system of claim 18 wherein the subscription request includes a common resource identifier associated with the tuple and used by a plurality of subscribers to subscribe to a plurality of services offered by the publisher.

20. The system of claim 18 wherein the tuple includes a plurality of elements and wherein the plurality of elements includes a virtual element associated with the customized information, and wherein the publish/subscribe service includes a subscription manager configured to create the first message using the virtual element of the tuple.

21. The system of claim 20 wherein the subscription manager is configured to generate the notification by using the virtual element of the tuple.

22. The system of claim 21 wherein the publish/subscribe service is configured to send the notification including the customized information to the subscriber using a directed notify command.
