Abstract
This paper presents OpenTeams, an open-source collaboration system built exclusively for handling digital twin development and management. For digital twins to work well, people from IoT, artificial intelligence and simulation have to collaborate, but most current tools are not designed for their special needs. By adopting a microservices format and centralising authentication, OpenTeams brings integration of communication, project management and document management to one platform. Deployment is done with Docker, identity is controlled using OpenLDAP and RocketChat, Jitsi, Wekan and Nextcloud are used to help with digital twin collaboration. Performance evaluation demonstrates significant improvements over traditional siloed approaches, with inter-service communication latency averaging 1.2ms, authentication overhead reduced by 87%, information fragmentation decreased by 63%, and task completion rates improved by 42%. Although the implementation delivers clear gains to digital twin teams, it also brings up problems related to complexity of configuration and the amount of resources needed. This framework allows organisations to collaborate for digital twins safely and efficiently which encourages more industries to use digital twin technology.
