The development of domain specific modeling languages has experienced a growing interest in the past years in industry and academia. This evolution can be attributed to the need to design, describe and analyze complex information systems in a coherent and consistent manner using a specific vocabulary and terminology from different background: model artefacts are not observed isolated anymore for a specific purpose, but need to be understood in the context of an organization ecosystem. In such an environment, domain specificity enables the modelers to express focused models using tailored domain concepts that are commonly understood by human stakeholders and at the after semantic transformation enable machine processing to generate model value. To enable such a setting, platform support for conceptual modeling is required that adapts iteratively to changing circumstances and domain needs.

This tutorial introduces the open-source metamodeling platform ADOxx as an experimentation environment for researchers and practitioners to realize individual meta-models and model processing functionalities for domain-specific conceptual modeling methods as modeling tools. Specific emphasis is given to the practical nature of the tutorial: participants are encouraged to realize their individual modeling tools in a hands-on setting and experiment with the capabilities of ADOxx to implement meta-models and model processing functionalities from scratch, specialize existing abstract fragments or compose and integrate available outcomes provided by the ADOxx.org community. The prototypes realized as part of the tutorial are available thereafter for further refinement, assessment and evaluation.
