    Beyond Low Code Platforms: The XModelerML --- an Integrated Multi-Level Modeling and Execution Environment
    (Modellierung 2022 Satellite Events, 2022) Frank, Ulrich; Mattei, Luca L.; Clark, Tony; Töpel, Daniel
    This paper presents the multi-level modeling tool XModelerML. It allows to create models that feature an arbitrary number of classification levels, thereby enabling the conjoint specification of modeling languages and their application within one diagram editor. The potential of multi-level modeling in general, of the XModelerML in particular is illustrated through three use cases.

    Goal Driven Architecture Development using LEAP
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 8, Nr. 1, 2013) Clark, Tony; Barn, Balbir
    Methods for goal driven system engineering exist and propose a number of categories of goals including behavioural, formal, informal and non-functional. This article goes further than existing goal driven approaches by linking goals directly to the semantics of an architectural modelling language called LEAP with an operational semantics. The behavioural goals are expressed using a Linear Temporal Logic and the non-functional goals are expressed as functions over meta-properties of the model. The meta-properties are supported using an encoding represented using Java reflection. The article describes the LEAP approach using a simple case study written in the LEAP language supported by the LEAP toolset.

    Introduction to the Special Issue on Model-Driven Organisations
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 3, 2018) Clark, Tony
    Modern organisations are faced with the very challenging problem of rapidly responding to continual external business pressures in order to sustain their competitiveness or to effectively perform mission-critical services. Difficulties arise because the continual evolution of systems and operational procedures that are performed in response to external pressures eventually lead to suboptimal configurations of systems and processes that drive the organisation.

    Multi-level Modelling with the FMMLx and the XModelerML
    (Modellierung 2020, 2020) Clark, Tony; Frank, Ulrich
    Multilevel modelling is a new modelling paradigm that enables additional abstraction through an unlimited number of classification levels and thus contributes to reuse, integration and flexibility. 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.
