What is the purpose of NGSI-9 in IoT systems?

The purpose of NGSI-9 in IoT systems is related to Context Entity Discovery. This standard is designed to support the management of context information in smart applications. NGSI-9 specifically allows for the discovery of context entities—these are the objects, devices, or data points within an IoT ecosystem that can provide relevant information for various applications.

In practice, NGSI-9 helps systems efficiently identify and retrieve the contextual information about these entities, enabling applications to understand their environment better and make informed decisions based on the current context. By fostering effective communication between different components in the Internet of Things, NGSI-9 ensures that applications can access real-time information regarding the state and behavior of the entities they interact with.

Understanding the role of NGSI-9 in facilitating Context Entity Discovery highlights its significance in developing responsive and context-aware IoT applications.
