MIM8: Local Digital Twins
This is the page describing OASC's MIM8 on Local Digital Twins (LDTs)
Description
This MIM describes interoperability in terms of the application domain of Local Digital Twins. In support of describing minimal interoperability mechanisms in this domain the MIM8 working group put forward a minimal definition of Local (or Urban) Digital Twins. This does not preclude any other definitions to be valid, and we recognise that depending on applications features may vary.
A Local (or Urban) Digital Twin is a digital representation of physical assets, systems, or processes in a defined local context (e.g., city, district, building, industry, port, airport). It leverages either on historical data, near real-time data, or real-time data enables visualization, analysis, simulation and reasoning for supporting decision-making.
The working group understands the diversity of local digital twins depending on their functionalities. Below is a table of different functionalities of a Local (or Urban) Digital Twin can have and as such are commonly categorised as: Awareness LDT, Experimental LDT, Predictive LDT, and Intelligent LDT (with human supervision).

*Analytics can include 'diagnostic', 'descriptive', 'predictive', and 'prescriptive' capabilities.
While we align with commonly agreed definitions (such as the one above), communities have expressed that simulations require more complex work process than analytics, and hence, experimental digital twins are viewed more complex as predictive LDTs.
We discern the following additional functionalities across the following layers (L):
