Supervisory control and data acquisition (SCADA) is a control system architecture comprising computers, networked data communications and graphical user interfaces (GUI) for high-level process supervisory management, while also comprising other peripheral devices like programmable logic controllers (PLC) and discrete proportional-integral-derivative (PID) controllers to interface with process plant or machinery. The use of SCADA has been considered also for management and operations of project-driven-process in construction.

Beginning in 2007, representatives from the Oil & Gas and Petrochemical industries participated in an OpenO&M End-User Advisory Group to provide the highest valued Use Cases with interoperability scenarios required for organizations to meet their business objectives. These have been continuously developed and refined through the OGI Pilot.


IoT, or 'The Internet of Things'  describes the network of physical objects that are embedded with sensors, software and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. IoT standards are provided by the OGC W3C consortium, using the Semantic Sensor Network ontology. This describes sensors and their observations, the involved procedures, the studied features of internet, and the observed properties, as well as actuators.


SensorML is an approved Open Geospatial Consortium standard. SensorML provides standard models and an XML encoding for describing sensors and measurement processes. SensorML can be used to describe a wide range of sensors, including both dynamic and stationary platforms and both in-situ and remote sensors.


Twin type models can be written in any text editor. The DTDL language follows JSON syntax, so you should store models with the extension .json. Using the JSON extension will enable many programming text editors to provide basic syntax checking and highlighting for your DTDL documents. There is also a DTDL extension available for Visual Studio Code.
