modessuch

Modessuch is a theoretical framework for the modular composition of complex systems. It treats a system as an assembly of independent units called modules, each exposing a well-defined interface and governed by explicit constraints that regulate their interaction. The framework emphasizes decoupling, composability, and traceability of design decisions.

The name combines “module” with the mathematical phrase “such that,” reflecting the framework’s emphasis on constraint-driven composition of modules. The term was coined in scholarly discussions to distinguish this formal approach from generic modular design by highlighting explicit specification of compatibility conditions.

Core ideas of modessuch include normalized interfaces, adapters or glue components to resolve mismatches, and a constraint solver that checks compatibility when modules are composed. It supports versioning and provenance tracking, enabling reproducibility of a given arrangement. The framework distinguishes three roles: providers (module authors), integrators (composers), and evaluators (validators).

Composition in modessuch is guided by a set of rules defining allowed connections, data flows, and behavioral contracts. The architecture supports both static composition (at design time) and dynamic, runtime assembly under monitoring and adaptation. This duality aims to accommodate evolving requirements while preserving system integrity.

Historically, modessuch has been discussed largely in theoretical and methodological contexts. It has been explored in software architecture, hardware configuration, and data-processing pipelines as a conceptual basis for studies on reconfigurable systems and model-driven engineering. Practical tooling remains a developing area, with ongoing work to establish scalable constraint handling and user-friendly specification languages.

A simple illustration is a data-processing chain built from modules: data source, transformer, filter, sink; modessuch specifies the input/output types and constraints to ensure the chain is valid. Related topics include modular design, component-based software engineering, constraint programming, and interface theory.
