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:

receiving via a network, by a first computing device, a request from a client device to create a first semantics related resource of a first plurality of semantics related resources on the first computing device, wherein the request comprises a request for a definition associated with a semantics description, wherein the first computing device is a first semantics node;

determining that the request for the definition associated with the semantics description resides on a second computing device, wherein the second computing device is a second semantics node and the second computing device comprises a second plurality of semantics related resources; and

responsive to the determining that the request for the definition associated with the semantics description resides on a second computing device, linking the semantics description to the definitions on the second semantics node, wherein the created linking is used for subsequent requests for semantics.

2. The method of claim 1, further comprising:

sending, by the first computing device, an update of the requested first semantics related resource on the second computing device when the first semantics related resource changes on the first computing device.

3. The method of claim 1, further comprising receiving, by the first computing device, a request to subscribe to receive updates for changes to the first semantics related resource.

4. The method of claim 1, wherein each of the first plurality of semantics related resources comprises one of a class, a relationship, or a term.

5. The method of claim 1, wherein each of the first plurality of semantics related resources has a universal resource identifier.

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

7. The method of claim 1, further comprising:

receiving a request to move a second semantics related resource of the first plurality of semantics related resources to a third computing device for query by the client 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 reaching the threshold of requests for the second semantics related resource.

9. A first 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;

receiving, from a client device via the network, a request to create a first semantics related resource of a first plurality of semantics related resources, wherein the request comprises a request for a definition associated with a semantics description;

determining that the request for the definition associated with the semantics description resides on a second semantics node, wherein the second semantics node comprises a second plurality of semantics related resources; and

responsive to the determining that the request for the definition associated with the semantics description resides on a second semantics node, linking the semantics description to the definitions on the second semantics node, wherein the created linking is used for subsequent requests for semantics.

10. The first semantics node of claim 9, wherein the operations further comprise retrieving the requested first semantics related resource from the second semantics node when the first semantics related resource is not included in a plurality of semantics related resources stored in the memory of the first semantics node.

11. The first semantics node of claim 9, wherein the operations further comprise subscribing to receive updates for changes to a second semantics related resource.

12. The first semantics node of claim 10, wherein the second semantics node is a parent semantics node.

13. The first semantics node of claim 9, wherein each of the first plurality of semantics related resources 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.

14. The first semantics node of claim 9, wherein the operations further comprise:

receiving a request to move a second semantics related resource of the first plurality of semantics related resources to a third semantics node for query by the client device;

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 first semantics node.

15. The first semantics node of claim 14, wherein the request to move the second semantics related resource is based on reaching the threshold of requests for the second semantics related resource.

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

receiving, from a client device via a network, a request from a client device to create a first semantics related resource of a first plurality of semantics related resources on the first computing device, wherein the request comprises a request for a definition associated with a semantics description, wherein the first computing device is a first semantics node;

determining that the request for the definition associated with the semantics description resides on a second computing device, wherein the second computing device is a second semantics node and the second computing device comprises a second plurality of semantics related resources; and

responsive to the determining that the request for the definition associated with the semantics description resides on a second computing device, linking the semantics description to the definitions on the second semantics node, wherein the created linking is used for subsequent requests for semantics.

17. The computer readable storage medium of claim 16, wherein the operations further comprise retrieving the requested first semantics related resource from the second computing device when the first semantics related resource is not included in the first plurality of semantics related resources stored on the first computing device.

18. The computer readable storage medium of claim 16, wherein each semantics related resource comprises one of a class, a relationship, or a term and each semantics related resource has a unified resource locator.

19. The computer readable storage medium of claim 16, wherein the operations further comprise subscribing to receive updates for changes to a second semantics related resource.
