Representing modelica models as knowledge graphs using the moont ontology

Model based design of building energy systems is increasingly used to enable efficient design flows. Different types of models have still to be converted manually, which is time consuming and error-prone. This turns out to be an obstacle for the integration of virtual validation by system simulations. As a contribution for automated conversion and translation of models, an ontology (MoOnt) has been developed that is utilized to represent Modelica simulation models as knowledge graphs (KG). An automated transcriptor that extracts KG from Modelica models has been implemented. A KG carrying the transcribed Modelica library and model representations was successfully queried for test cases. This is the basis towards further steps for automated translation of different types of models in the design process of buildings and a contribution to the model based design of building energy systems.
