Digital Twin Instance at the Edge
It would be highly useful for OT edge application development to be able to run a micro instance of digital twins at the edge. This could have functionality such as synchronising models between Edge Twin and Cloud Twin (similar to plug and play).
On the edge gateway the Edge Digital Twin instance could be used to interface with tinyML apps, Industrial Protocol Conversion mapping, Southbound Device states etc.
The use-case would be smart cities where the edge gateways are provided to Field Teams within a specific domain (Waste, Energy, Water, Lighting, etc). It allows those teams to develop their models over time but automatically feeds their twins into the centralised Smart City Twin.
