Abstract

Semantics nodes provide semantics support in machine-to-machine (M2M) systems. In an embodiment, a semantics node may manage semantics related resources capable of being discovered, retrieved, or validated by other devices. In another embodiment, the semantics node may be discovered by other nodes, and semantics related resources may be discovered with subscription mechanisms.

Claims

1. A method comprising:

storing a plurality of semantics related resources in a memory of a first computing device;

receiving via a network, by the first computing device, a request from a client for a first semantics related resource; and

when the requested first semantics related resource is one of the plurality of semantics related resources stored on the first computing device, transmitting to the client via the network, by the first computing device, the first semantics related resource.

2. The method of claim 1, further comprising:

retrieving, by the first computing device, the requested first semantics related resource from a second computing device when the first semantics related resource is not included in the plurality of semantics related resources stored on the first computing device.

3. The method of claim 1, further comprising subscribing to receive updates for changes to a second semantics related resource.

4. The method of claim 1, wherein each semantics related resource comprises one of a class, a relationship, or a term.

5. The method of claim 1, wherein each semantics related resource has a universal resource identifier or a unified resource locator.

6. The method of claim 2, wherein the second computing device is a parent semantics node or a child semantics node.

7. The method of claim 1, further comprising:

receiving a request to move a second semantics related resource of the plurality of semantics related resources to a third computing device;

forwarding the second semantics related resource to the third computing device; and

subsequent to forwarding the second semantics related resource to the third computing device, deleting the second semantics related resource from the first computing device.

8. The method of claim 7, wherein the request to move the second semantics related resource is based on surpassing a threshold number of requests for the second semantics related resource.

9. The method of claim 1, further comprising linking the first semantics related resource based on semantics similarity of a second semantics related resource.

10. A semantics node comprising:

a processor;

a transmit/receive element for communicating with a network; and

a memory coupled to the processor, the memory comprising executable instructions that when executed by the processor cause the semantic node to effectuate operations comprising;

storing a plurality of semantics related resources in the memory of the semantics node;

receiving, from a client via the network, a request for a first semantics related resource; and

when the requested first semantics related resource is one of the plurality of semantics related resources stored in the memory of the semantics node, transmitting, to the client via the network, the first semantics related resource.

11. The semantics node of claim 10, wherein the operations further comprise retrieving the requested first semantics related resource from a second semantics node when the first semantics related resource is not included in the plurality of semantics related resources stored in the memory of the semantics node.

12. The semantics node of claim 10, wherein the operations further comprise subscribing to receive updates for changes to a second semantics related resource.

13. The semantics node of claim 11, wherein the second semantics node is a parent semantics node or a child semantics node.

14. The semantics node of claim 10, wherein each semantics related resource comprises one of a class, a relationship, or a term, and each semantics related resource has a universal resource identifier or a unified resource locator.

15. The semantics node of claim 10, wherein the operations further comprise:

receiving a request to move a second semantics related resource of the plurality of semantics related resources to a third semantics node;

forwarding the second semantics related resource to the second semantics node; and

subsequent to forwarding the second semantics related resource to the second semantics node, deleting the second semantics related resource from the memory of the semantics node.

16. The semantics node of claim 15, wherein the request to move the second semantics related resource is based on surpassing a threshold number of requests for the second semantics related resource.

17. A computer readable storage medium comprising computer executable instructions that when executed by a processor of a computing device cause the computing device to perform operations comprising:

storing a plurality of semantics related resources in a memory of the computing device;

receiving, from a client via a network, a request for a first semantics related resource; and

when the requested first semantics related resource is one of the plurality of semantics related resources stored in the memory of the computing device, transmitting to the client via the network the first semantics related resource.

18. The computer readable storage medium of claim 17, wherein the operations further comprise retrieving the requested first semantics related resource from a second semantics node when the first semantics related resource is not included in the plurality of semantics related resources stored in the memory of the computing device.

19. The computer readable storage medium of claim 17, wherein each semantics related resource comprises one of a class, a relationship, or a term and each semantics related resource has a universal resource identifier or a unified resource locator.

20. The computer readable storage medium of claim 17, wherein the operations further comprise subscribing to receive updates for changes to a second semantics related resource.
