ITU-T Y.4473 (08/2020)

传感物API – 传感

ITU-T Y.4473建议书规定了传感物联网应用编程接口（API），该接口提供了一个基于开放标准和地理空间的框架，通过网络互连物联网（IoT）设备、数据和应用。
传感物联网（SensorThings）应用编程接口是一个开放的标准，这意味着接口并非专有且与平台无关。此编程接口是建立在一套行之有效且被广泛采用的开放标准之上，如网络协议和开放地理空间联盟（OGC）传感器网络支持（SWE）的标准，其中包括ISO/OGC观测和测量数据模型。传感物联网应用编程接口是可扩展的，不仅可应用于简单用例，亦可用于复杂的用例。
本建议书提供了一种标准方法，用于管理和检索来自异构物联网传感器系统的观察结果和元数据。传感物联网应用编程接口使用了代表性状态传输（REST）原则、高效的JavaScript对象符号（JSON）编码、消息队列遥测传输（MQTT）协议、灵活的OASIS开放数据协议（OData）和统一资源定位符（URL）约定。
