Whilst bIoTope should be understood as a highly flexible and dynamic ecosystem capable of seamlessly integrating arbitrary proprietary IoT platforms, it nevertheless builds upon several core components, which provide essential functionality. Those functionalities referenced in this article, are agnostic to other ecosystem-external systems. Inside of the ecosystem, a micro-service-architecture MSA approach is applied. Using O-MI for technical Interoperability and O-DF for syntactic and semantic interoperability are foundation pillars of the ecosystem.
