Internet of things device hierarchies

One or more non-transitory computer-readable media (CRM) containing instructions written thereon that, in response to execution by an Internet of Things (IoT) device, cause the IoT device to:

• respond to set requests to set attributes of a first resource of the device, uniquely identified by a first unique resource identifier (URI), from a plurality of other resources disposed among other IoT devices that in conjunction with the IoT device form an IoT device hierarchy with at least three hierarchical levels;
• respond to get requests with a plurality of properties of the first resource, wherein:
• the plurality of properties includes a hierarchical interface property that indicates support for accessing related ones of the plurality of resources in a hierarchical manner, and at least one of a parent URI property or a child URI property;
• wherein:
• the parent URI property, when included, has a property value that identifies a second URI of a second resource of the plurality of resources disposed at a second of the at least three hierarchical levels, the second resource having a parent resource relationship to the first resource in the IoT device hierarchy;
• and
• the child URI property, when included, has a property value that identifies a third URI of a third resource of the plurality of resources disposed at a third of the at least three hierarchical levels, the third resource having a child resource relationship to the first resource;
• and
• wherein:
• support for accessing related ones of the plurality of resources in a hierarchical manner includes support for accessing fourth one or more of the plurality of resources disposed at a fourth level of the IoT device hierarchy, the fourth one or more resources being child or children resources of fifth one or more of the plurality of resources disposed at a fifth level of the IoT device hierarchy higher than the fourth level, via a single request to a sixth of the plurality of resource disposed at a sixth level of the IoT device hierarchy higher than the fifth level, the fifth one or more resources being child or children resource of the sixth resource.

A computer-implemented method comprising:

• responding, by an Internet-of-Things (IoT) device, to requests to set attributes of a first resource, wherein the first resource is identified by a unique resource identifier (URI), among a plurality of resources disposed among IoT devices of an IoT device hierarchy having at least three hierarchical levels;
• responding, by the IoT device, to requests for properties of the first resource, wherein:
• the plurality of properties includes a hierarchical interface property that indicates support for accessing related ones of the resources in a hierarchical manner, and at least one of a parent URI property or a child URI property;
• the parent URI property, when included, has a property value that identifies a second URI of a second resource of the plurality of resources disposed at a second of the at least three hierarchical levels, the second resource having a parent resource relationship to the first resource in the IoT device hierarchy;
• and
• the child URI property, when included, has a property value that identifies a third URI of a third resource of the plurality of resources disposed at a third of the at least three hierarchical levels, the third resource having a child resource relationship to the first resource;
• and
• wherein
• support for accessing related ones of the plurality of resources in a hierarchical manner includes support for accessing fourth one or more of the plurality of resources disposed at a fourth level of the IoT device hierarchy, the fourth one or more resources being child or children resources of fifth one or more of the plurality of resources disposed at a fifth level of the IoT device hierarchy higher than the fourth level, via a single request to a sixth of the plurality of resource disposed at a sixth level of the IoT device hierarchy higher than the fifth level, the fifth one or more resources being child or children resources of the sixth resource.
