Apache IoTDB is a column-oriented open-source, time-series database (TSDB) management system written in Java. [1] It has both edge and cloud versions, provides an optimized columnar file format for efficient time-series data storage, and TSDB with high ingestion rate, low latency queries and data analysis support.
CBOR encoded data is seen as a stream of data items. Each data item consists of a header byte containing a 3-bit type and 5-bit short count. This is followed by an optional extended count (if the short count is in the range 24–27), and an optional payload. For types 0, 1, and 7, there is no payload; the count is the value. For types 2 (byte ...
SensorThings API [1] is an Open Geospatial Consortium (OGC) standard providing an open and unified framework to interconnect IoT sensing devices, data, and applications over the Web. It is an open standard addressing the syntactic interoperability and semantic interoperability of the Internet of Things.
It is important to the IIoT subset of the IoT. O-DF: Open Data Format: O-DF is a standard published by the Internet of Things Work Group of The Open Group in 2014, ...
The GSMA "IoT Big Data Framework Architecture" is based on NGSI-LD. [23] The Fed4IoT EU project, where it is used as a neutral data format [24] for translating between various IoT data representations; The Thing'in graph-based digital twin platform from Orange uses NGSI-LD as its core information model.

Constrained Application Protocol (CoAP) is a specialized UDP-based Internet application protocol for constrained devices, as defined in RFC 7252.It enables those constrained devices called "nodes" to communicate with the wider Internet using similar protocols.
The Open Geospatial Consortium (OGC) is an international voluntary consensus standards organization that develops and maintains international standards for geospatial content and location-based services, sensor web, Internet of Things, GIS data processing and data sharing. The OGC was incorporated as a not for profit in 1994.
OMA Lightweight M2M (LwM2M) is a protocol from the Open Mobile Alliance for machine to machine (M2M) or Internet of things (IoT) device management and service enablement. [1] The LwM2M standard defines the application layer communication protocol between an LwM2M Server and an LwM2M Client which is located in an IoT device.
