Aggregation of information models — An OPC UA based approach to a holistic model of models

Information modelling is one of the important aspects in today's automation scenario. Currently there are numerous information modelling standards available which focus on specific independent aspects of the whole system. In case information is needed from multiple information models each modelling a different aspect of the system, it results in a mesh like scenario. This paper discusses an approach to resolve the resulting mesh scenario. The initial sections discuss the problem in greater detail, thereafter introducing the concept of Aggregation and how it could be a possible solution. Finally, the paper presents an architecture which can be taken as a guideline for implementation purposes.
