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.
The Thing Description (TD) (or W3C WoT Thing Description (TD)) is a royalty-free, open information model with a JSON based representation format for the Internet of Things (IoT). A TD provides a unified way to describe the capabilities of an IoT device or service with its offered data model and functions, protocol usage, and further metadata.
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.
Open Data Format O-DF is a standard published by the Internet of Things Work Group of The Open Group in 2014, which specifies a generic information model structure that is meant to be applicable for describing any "Thing", as well as for publishing, updating and querying information when used together with O-MI (Open Messaging Interface).
YANG is a modular language representing data structures in an XML tree format. The data modeling language comes with a number of built-in data types. Additional application specific data types can be derived from the built-in data types. More complex reusable data structures can be represented as groupings.
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.
The format was created by Scott Ferguson and Daniel A. Chayes. [2] [3] The file format specifications and C source code for a library to read and write GSF files are available from Leidos, [1] who maintain both the format specification and the source code. [3] The GSF library source code is published under the GNU Lesser General Public License ...
Linked open data are linked data that are open data. [ 5 ] [ 6 ] [ 7 ] Tim Berners-Lee gives the clearest definition of linked open data as differentiated from linked data. Linked Open Data (LOD) is Linked Data which is released under an open license, which does not impede its reuse for free.
