The XModeler is a language engineering tool that allows for the common representation of (meta) models and code. The multi-level modelling and execution language FMMLx is implemented in the XModeler by extending its genuine meta model. This tutorial provides a comprehensive introduction into the foundations of multi-level modelling and its application. It will be shown how multi-level modelling enables relaxing fundamental conflicts of system design. During a practical exercise with the XModelerML, the participants will experience a new style of modelling that integrates language design with traditional ways of modelling.enConceptual ModellingModel-Based Development and MaintenanceSelf-Referential Enterprise SystemsText1617-5468
