3. The apparatus of claim 1 , further comprising:
an interface for communicating with web applications making use of the node resources; and
a component for receiving subscriptions regarding the information received from the nodes and providing the subscribed information.
4. The apparatus of claim 1 , wherein the communication further comprises issuing a request to one of the plurality of nodes regarding an embedded resource of that node, wherein the request includes the unique static ID of the embedded node resource, and receiving, in response to the request, a notification of the value of the embedded node resource.
5. An apparatus comprising:
at least one processor; and
at least one memory including computer program code configured to, with the at least one processor, cause the apparatus at least to:
control connections to embedded node resources providing information;
store a unique static ID for each of the plurality of resources;
communicate, utilizing an interface, with a network element operationally connected to the apparatus;
send the network element a registration message that:
indicates the unique static ID for each of the resources of the node, wherein the unique static ID for each resource is unique within the node, and
includes an indication of which resources the node is configured to autonomously send information about, in response to an auto-observable, embedded node resource value change, wherein the information to be autonomously sent indicates the unique static ID of the auto-observable, embedded node resource; and
receive an acknowledgment from the network element indicating that the resource has been registered and marked as auto-observable.
6. The apparatus of claim 5 , wherein the apparatus is configured to send the network element information autonomously regarding the changed auto-observable, embedded node resource together with the unique static ID of the auto-observable resource.
7. The apparatus of claim 5 , wherein the apparatus is configured to respond to the request by transmitting requested information to the network element, the transmission comprising the unique static ID of the embedded node resource.
8. The apparatus of claim 5 , further configured to receive a request regarding an embedded node resource of the apparatus, wherein the request includes the unique static ID of the embedded node resource, and send, in response to the request, a notification of the value of the embedded node resource.
9. A method comprising:
communicating with at least one of a plurality of nodes operationally connected to an apparatus using at least one processor of the apparatus,
wherein each of the plurality of nodes comprises a plurality of embedded node resources,
wherein each of the embedded node resources is assigned a unique static ID within that node, and
wherein the communication includes receiving, from each of the plurality of nodes, a registration message that indicates the unique static ID for each of the plurality of embedded node resources for the node, and an indication of which resources the node is configured to autonomously send information about, in response to an auto-observable, embedded node resource value change,
wherein the information to be autonomously sent includes an indication of the unique static ID of the auto-observable, embedded node resource, and
storing data indicating which embedded node resource is auto-observable.
10. The method of claim 9 , further comprising receiving the autonomously sent information sent regarding the changed auto-observable, embedded node resource change together with the static ID of the auto-observable resource.
11. The method of claim 9 , further comprising communicating with web applications making use of the resources of the nodes, and receiving subscriptions regarding the information received from the nodes and providing the subscribed information.
12. The method of claim 9 , wherein the communication further comprises issuing a request to one of the plurality of nodes regarding an embedded resource of that node, wherein the request includes the unique static ID of the embedded node resource, and receiving, in response to the request, a notification of the value of the embedded node resource.
13. A method comprising:
controlling connections to each of a plurality of resources embedded in a node providing information;
storing a unique static ID for each of the plurality of resources;
communicating, utilizing an interface, with a network element operationally connected to the apparatus;
sending the network element a registration message that:
indicates the unique static ID for each of the resources of the node, wherein the unique static ID for each resource is unique within the node, and
includes an indication of which resources the node is configured to autonomously send information about, in response to an auto-observable, embedded node resource value change, wherein the information to be autonomously sent indicates the unique static ID of the auto-observable, embedded node resource; and
receiving an acknowledgment from the network element indicating that the resource has been registered with the unique static ID and marked as auto-observable.
14. The method of claim 13 , further comprising sending the network element information autonomously regarding the changed auto-observable, embedded node resource together with the static ID of the auto-observable resource.
15. The method of claim 13 , further comprising receiving, from the network element, a request regarding a resource, the request comprising the unique static ID of the embedded node resource, and responding to the request by transmitting requested information to the network element, the transmission comprising the unique static ID of the embedded node resource.
16. A non-transitory computer program product encoding a computer program of instructions for executing a computer process carrying out a method when the instructions are performed on a computer, wherein the method comprises:
controlling connections to each of a plurality of resources embedded in a node providing information;
storing a unique static ID for each of the plurality of resources;
