modelingto

Modelingto is a conceptual framework and ecosystem for building, exchanging, and validating computational models across disciplines. The term emerged in academic and industry discussions as a proposed standard for model interoperability, reusability, and reproducibility, with an emphasis on collaborative development.

Overview and concepts: Modelingto combines a declarative modeling approach with a modular component architecture. Models are described using a high-level specification that separates model structure from numerical solving, enabling solver interchange without altering the core model. The framework supports multiple modeling paradigms, including agent-based, discrete-event, and continuous-time dynamics, and provides a unified runtime to execute models across diverse environments.

Architecture and components: Core elements include the Modelingto Core specification, a library of reusable components (agents, resources, processes), a Modelingto Studio for composition and visualization, and a repository for versioned model artifacts. Provenance and result tracking are integral features, with automatic capture of parameters, data, and analytical outcomes to support reproducibility and auditability.

Validation and interoperability: Modelingto emphasizes test-driven validation, standardized data representations, and fixture-based benchmarking. Interoperability is advanced through adapters that translate existing modeling formats into the Modelingto representation, enabling cross-tool reuse and collaborative development.

Applications and adoption: The concept has found interest in research and education across engineering, biology, economics, and social sciences. It is used to prototype experiments, teach modeling concepts, and facilitate collaborative model development. Adoption varies by domain and tooling maturity, reflecting its status as a community-driven framework rather than a single official standard.
