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 the generations of support tools for visual languages, the 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

The workshop format follows the idea of a working workshop with a highly interactive, inclusive, and participative audience rather than the mode classical mini-conference format.

The technical program will feature a well-balanced combination of

  • Visualization techniques and methodologies for modeling languages
  • Visualizing models for different stakeholders/readers
  • Visualizing errors in models (incompleteness, inconsistency, incorrectness)

The invited presentations will be given by prominent researchers in the field covered by the workshop topics. At the same time, the challenge and position presentations will be selected through a selection process.

The selected presentation proposal consists of a four-page article

  • Position presentation: the proponent prospects her/his vision on a medium to overcome current limitations, disclose further application opportunities, or to present visionary ideas to be realized in the medium or long run
  • Challenge presentation: the proponent prospects a presentation illustrating and motivating one of the grand challenges affecting the field

Contributions must be written in English, adhere to the Springer LNCS formatting guidelines, and be submitted through EasyChair. All submissions must be original work and must not have been previously published or being under review elsewhere.

For each accepted presentation, at least one of the authors must register for the workshop, participate fully in the workshop.
