LIGHTWEIGHT IOT INFORMATION MODEL

摘要

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 method comprising:
generating, at a first entity in a network of connected entities, a request to perform an action, the request comprising:
a source subject of a first subject information object type, wherein the first subject information object type is selected from a predetermined set of subject information object types,the action of a first action information object type, wherein the first action information object type is selected from a predetermined set of action information object types, anda target subject of a second subject information object type, wherein the second subject information object type is selected from the predetermined set of subject information object types; and transmitting the request from the first entity to a second entity, wherein the request causes the second entity to perform the action based on the source subject and the target subject.
