Digital Twin Operational Platform for Connectivity and Accessibility using Flask Python

This paper demonstrates an example of an open-source, modular, and system independent framework that has been developed by a team of researchers working for the UK based DigiTwin project. The example in this paper is based on a framework for a digital twin operational platform (DTOP) that uses Flask Python, and is named DTOP-Cristallo. DTOPCristallo is an operational platform that uses HTML web pages as the interface between the digital twin simulations, both python based and 3rd party software based, and the user. This framework is particularly useful for connectivity with users, since it can deploy the digital twin with multiple accessibility options to accommodate a wide variety of intended uses.
