The sheer complexity of software systems nowadays made modeling artifacts pervasive throughout the development process, be use requirements, analysis, design, or development. Whether models are used for communication or prescriptive purposes, their syntax and pragmatics affect the usability and represent contributory factors concerning the accidental complexity. The diversity of modeling notations and approaches permit to classify them according to different taxonomies. General-purpose and domain-specific modeling languages can be created with different intended scopes, although all of them can make use of graphical, textual, maps, matrices, tables, and combinations regarding its concrete syntax. These representations have the undoubted advantage of capture and increase understanding of complex software systems and better grasp the rationale behind them. In essence, a visual modeling language creates a joint base for the modeler by improving their communication and lays a solid foundation for the implementation.

FPVM 2021 aims to promote and foster discussions on many aspects of visual modeling languages, including novel and visionary ideas and techniques, notations for more expressive and enhanced model modeling environments, technical editors, and usability of tools and meta-tools.


Topics of interest are but are not limited to

  • Visualization techniques and methodologies for modeling languages
  • Visualizing models for different stakeholders/readers
  • Visualizing errors in models (incompleteness, inconsistency, incorrectness)
  • Guidance in modeling languages
  • Visualizing version data of models
  • Visualizing different views
  • Complex or large-scale model visualization
  • Usability for visual modeling languages
  • Meta-editors novel approaches
  • Development of collaborative (human-in-the-loop) visual modeling languages
  • Visual Modeling platforms for cloud applications
  • LowCode/NoCode techniques and methodologies
