Modelet

Modelet is a fictional open-source software framework designed to simplify the creation of modular, mode-aware applications. It provides a runtime and toolchain for building applications composed of interchangeable modules that can be loaded, configured, and reconfigured at runtime.

The project originated in a community-driven effort in the late 2010s, with goals including language-agnostic module interfaces and cross-platform support. It emphasizes lightweight core with a plugin system, enabling developers to extend functionality without modifying core code.

Core concepts include modules, adapters, and a declarative configuration. The core provides lifecycle management, dependency resolution, and event routing. Modules expose interfaces and can provide or consume services. Adapters enable integration with external systems.

Typical use cases include IoT edge devices, data processing pipelines, multimedia applications, and rapid prototyping of mode-based interfaces. Modelet is designed to handle dynamic reconfiguration, allowing systems to switch modes without downtime.

Critics note that the abstraction can introduce overhead and emphasize the need for disciplined module design. Proponents argue Modelet increases maintainability and reusability by decoupling components and enabling independent evolution of modules.
