WebML is a domain-specific language used to design complex data-intensive Web
applications at a conceptual level. As WebML was devised to support design tasks, the need …

This research was aimed at eliciting the requirements of practitioners who use conceptual
modeling in their professional work for the visual notations of modeling languages. While the …

Graph transformations are one of the best known approaches for defining transformations in
model-based software development. They are defined over the abstract syntax of source …

This paper presents the DPFWorkbench, a diagrammatic tool for domain specific modelling.
The tool is an implementation of the basic ideas from the Diagram Predicate Framework …

Existing grammars generate Finite Deterministic DEVS models, a restricted subset of DEVS.
The proposed context-free grammar generates the unrestricted set of Classic DEVS models …

This paper presents the DPF Workbench, a language workbench for (meta) modelling and
code generation. The DPF Workbench includes a graphical specification editor for the …

We present an implementation of the OMG's Human-Usable Textual Notation (HUTN)[6] that
provides a generic concrete syntax for MOF-based metamodels. The notation is …

Iconic languages can represent concepts by the combination of graphical components (such
as colors or pictograms). There are numerous examples, from traffic signs to computer user …

We present the new notion of enforced generative pattern, a structure that declares positive
or negative conditions that must be satisfied by a model. Patterns are applied to …

The least cognitively demanding way to create a diagram is to draw it with a pen. Yet there is
also a need for more formal visualizations, that is, diagrams created using both traditional …
