Abstract

A method, system and computer program product for maintaining federated name context bindings in a name space is disclosed. A reference within a first name space of a first system is bound with a durable subscription to a second name space on a second system. The binding of the first reference to the second name space is administered with a graphical user interface. A durable subscription is established with the second system for the binding utilizing communication with the second system over a network. Notification of a change affecting the bindings from the second system is received and the reference is rebound in the first name space.

Claims

1. A method for maintaining federated name context bindings in a name space, said method comprising:

binding, with a durable subscription, a first reference within a first name space of a first system to a second name space on a second system;

administering with a graphical user interface said binding of said first reference to said second name space;

establishing a durable subscription with said second system for said binding utilizing communication with said second system over a network;

receiving notification of a change affecting said binding from said second system; and

rebinding said reference in said first name space.

2. The method of claim 1, wherein said step of binding with said durable subscription said first system with said first name space containing said first reference to said second name space on said second system further comprises binding with said durable subscription over an encrypted link said first system with said first name space containing said first reference to said second name space on said second system.

3. The method of claim 1, wherein said rebinding step further comprises rebinding to a third name space on said second system all references in said first name space on said first system that are bound to said second system.

4. The method of claim 1, wherein said rebinding step further comprises rebinding to a third name space on said second system an identified list of references on said first system received from said second system.

5. The method of claim 1, wherein said step of binding, with said durable subscription, said first reference further comprises transmitting to said second system a data record identifying a naming context in said second system associated with said first reference on said first system.

6. The method of claim 1, wherein said step of binding with said durable subscription said first system with said first name space containing said first reference to said second name space on a second system further comprises storing one or more details of said durable subscription on a persistent medium accessible to said second system.

7. The method of claim 1, wherein said step of establishing further comprises transmitting a first server address, a subscription server address, and a reference identifier for said first reference.

8. A system for maintaining federated name context bindings in a name space, said system comprising:

means for binding, with a durable subscription, a first reference within a first name space of a first system to a second name space on a second system;

means for administering with a graphical user interface said binding of said first reference to said second name space;

means for establishing a durable subscription with said second system for said binding utilizing communication with said second system over a network;

means for receiving notification of a change affecting said binding from said second system; and

means for rebinding said reference in said first name space.

9. The system of claim 8, wherein said means for binding with said durable subscription said first system with said first name space containing said first reference to said second name space on said second system further comprises means for binding with said durable subscription over an encrypted link said first system with said first name space containing said first reference to said second name space on said second system.

10. The system of claim 8, wherein said rebinding means further comprises means for rebinding to a third name space on said second system all references in said first name space on said first system that are bound to said second system.

11. The system of claim 8, wherein said rebinding means further comprises means for rebinding to a third name space on said second system an identified list of references on said first system received from said second system.

12. The system of claim 8, wherein said means for binding, with said durable subscription, said first reference further comprises means for transmitting to said second system a data record identifying a naming context in said second system associated with said first reference on said first system.

13. The system of claim 8, wherein said means for binding with said durable subscription said first system with said first name space containing said first reference to said second name space on a second system further comprises means for storing one or more details of said durable subscription on a persistent medium accessible to said second system.

14. The system of claim 8, wherein said means for establishing further comprises means for transmitting a first server address, a subscription server address, and a reference identifier for said first reference.

15. A machine-readable medium having a plurality of instructions processable by a machine embodied therein, wherein said plurality of instructions, when processed by said machine, causes said machine to perform a method for maintaining federated name context bindings in a name space, said method comprising:

binding, with a durable subscription, a first reference within a first name space of a first system to a second name space on a second system;

administering with a graphical user interface said binding of said first reference to said second name space;

establishing a durable subscription with said second system for said binding utilizing communication with said second system over a network;

receiving notification of a change affecting said binding from said second system; and

rebinding said reference in said first name space.

16. The machine-readable medium of claim 15, wherein said step of binding with said durable subscription said first system with said first name space containing said first reference to said second name space on said second system further comprises binding with said durable subscription over an encrypted link said first system with said first name space containing said first reference to said second name space on said second system.

17. The machine-readable medium of claim 15, wherein said rebinding step further comprises rebinding to a third name space on said second system all references in said first name space on said first system that are bound to said second system.

18. The machine-readable medium of claim 15, wherein said rebinding step further comprises rebinding to a third name space on said second system an identified list of references on said first system received from said second system.

19. The machine-readable medium of claim 15, wherein said step of binding, with said durable subscription, said first reference further comprises transmitting to said second system a data record identifying a naming context in said second system associated with said first reference on said first system.

20. The machine-readable medium of claim 15, wherein said step of binding with said durable subscription said first system with said first name space containing said first reference to said second name space on a second system further comprises storing one or more details of said durable subscription on a persistent medium accessible to said second system.
