Lightweight IoT information model
A lightweight and extensible information model for machine-to-machine systems is disclosed. A service layer information management architecture uses three categories of atomic objects, subjects, actions, and descriptions. Information for use within the model is built using the atomic information objects. Application programming interfaces are used to perform operations and information processing by different nodes. Common service functions are used in the model as instances of a generic common service information model.
1. A first network apparatus in a network, the first network apparatus comprising:
a memory comprising executable instructions; and
a processor that, when executing the executable instructions, effectuates operations comprising:
receiving, from a second network apparatus in the network, a RESTful request to create at least one application-specific instance of an information model object in a RESTful architecture, wherein the request comprises:
at least one information model object description in the RESTful architecture, wherein the at least one information model object description is application-specific and is provided by a first entity executing on the second network apparatus; and
wherein the at least one information model object comprises a description of a uniquely addressable resource in the network; and
wherein the description comprises one or more characteristics, states, statuses, or any other attributes of the information model object; and
creating the at least one application-specific instance of the information model object based on the at least one information model object description received from the second network apparatus;
wherein the application-specific instance of a information model object is accessible via RESTful requests issued by other entities implemented on other network apparatuses in the network,
wherein the request to create the application-specific instance of a information model object further comprises one or more object creation rules, and
wherein creating the at least one application-specific instance of a information model object comprises creating the at least one application-specific instance of the information model object in accordance with the one or more object creation rules.
2. The first network apparatus of claim 1 , wherein the operations further comprise restricting use of the at least one application-specific instance by only the first entity executing on the second network apparatus.
3. The first network apparatus of claim 1 , wherein the operations further comprise transmitting a response to the second network apparatus via the communication network comprising a confirmation of the creation of the at least one application-specific object instance.
4. The first network apparatus of claim 1 , wherein the operations further comprise transmitting a response to the second network apparatus in the network comprising an identifier for the at least one application-specific object instance.
5. The first network apparatus of claim 1 , wherein the operations further comprise transmitting a response to the second network apparatus in the network comprising an attribute that identifies a type of the at least one application-specific object instance.
6. The first network apparatus of claim 1 , wherein the operations further comprise advertising the at least one application-specific object instance to another network apparatus in the network.
7. The first network apparatus of claim 6 , wherein the operations further comprise sending to the another network apparatus the at least one application-specific object instance in response to a retrieve message received from the another network apparatus.
8. The first network apparatus of claim 1 , wherein the information model object is defined in a service layer of the network.
9. The first network apparatus of claim 8 , wherein the service layer comprises common service layer function for M2M service.
10. The first network apparatus of claim 9 , wherein the common service layer function is defined according to ETSI or oneM2M standards.
11. A method for a first entity in a network, the method comprising:
receiving, from a second network apparatus in the network, a RESTful request to create at least one application-specific instance of a information model object in a RESTful architecture, wherein the request comprises:
at least one information model object description in the RESTful architecture, wherein the at least one information model object description is application-specific and is provided by a first entity executing on the second network apparatus; and
wherein the at least one information model object comprises a description of a uniquely addressable resource in the network; and
wherein the description comprises one or more characteristics, states, statuses, or any other attributes of the information object; and
creating the at least one application-specific instance of the information model object based on the at least one information model object description received from the second network apparatus;
wherein the application-specific instance of a information model object is accessible via RESTful requests issued by other entities implemented on other network apparatuses in the network,
wherein the request to create the application-specific instance of a information model object further comprises one or more object creation rules, and
wherein creating the at least one application-specific instance of a information model object comprises creating the at least one application-specific instance of the information model object in accordance with the one or more object creation rules.
12. The method of claim 11 , further comprising restricting use of the at least one application-specific instance by only the first entity executing on the second network apparatus.
13. The method of claim 11 , further comprising transmitting a response to the second network apparatus via the communication network comprising a confirmation of the creation of the at least one application-specific object instance.
14. The method of claim 11 , further comprising transmitting a response to the second network apparatus in the network comprising an identifier for the at least one application-specific object instance.
15. The method of claim 11 , further comprising transmitting a response to the second network apparatus in the network comprising an attribute that identifies a type of the at least one application-specific object instance.
16. The method of claim 11 , further comprising advertising the at least one application-specific object instance to another network apparatus in the network.
17. The method of claim 16 , further comprising sending to the another network apparatus the at least one application-specific object instance in response to a retrieve message received from the another network apparatus.
18. The method of claim 11 , wherein the information model object is defined in a service layer of the network.
19. The method of claim 18 , wherein the service layer comprises common service layer function for M2M service.
20. The method of claim 19 , wherein the common service layer function is defined according to ETSI or oneM2M standards.
