Meta-Information driven Modeling of Services for Experimentable Digital Twins

Experimental Digital Twins (EDT) provide a comprehensive view on the behavior of Cyber-Physical Systems (CPS). This is achieved by simulation technology and the application of virtual environments to develop and test desired functionality, including models, data structures, services and communication capabilities. This paper outlines a meta-information driven method of describing services provided by a CPS for consumption by peers via any means of communication. In addition, a set of application rules is presented, which handle cases such as service composition and the interaction of CPS components in distributed systems. We present the fundamental meta-information system that facilitates the specification process by providing the necessary type information for the dynamic object construction and automated (de-)serialization of data passed between provider and consumer.
