We invite authors to submit papers that discuss and analyze research challenges and experiences pertaining to software and system modeling languages, techniques, tools, practices and other facets. The following are some of the topic areas that are of special interest, but the journal publishes on a wide range of software and systems modeling concerns:

Domain-specific models and modeling standards;

Model-based testing techniques;

Model-based simulation techniques;

Formal syntax and semantics of modeling languages such as the UML;

Rigorous model-based analysis;

Model composition, refinement and transformation;

Software Language Engineering;

Modeling Languages in Science and Engineering;

Language Adaptation and Composition;

Metamodeling techniques;

Measuring quality of models and languages;

Ontological approaches to model engineering;

Generating test and code artifacts from models;

Model synthesis;

Methodology;

Model development tool environments;

Modeling Cyberphysical Systems;

Data intensive modeling;

Derivation of explicit models from data;

Case studies and experience reports with significant modeling lessons learned;

Comparative analyses of modeling languages and techniques;

Scientific assessment of modeling practices
