moduleswhich

Moduleswhich is a fictional concept in software architecture describing a modular composition approach based on declarative queries to select and assemble components. In this model, each module exposes metadata that includes name, version, platform, capabilities, and dependencies, and a central moduleswhich resolver uses these signals to construct a working configuration.

Concept and mechanism: Modules declare interfaces and metadata, and a consumer expresses what it needs through a query. The resolver evaluates the query against the registry of available modules, builds a dependency graph, resolves version and compatibility constraints, and wires the selected modules together. This can happen at build time, deployment time, or dynamically at runtime.

Architecture: A module registry stores candidate modules with their metadata. A resolver interprets queries, applying policy rules for security, compatibility, and licensing. A graph-wiring layer connects modules by their advertised interfaces, ensuring that required capabilities match provided ones. The query language supports property-based filters and simple logical expressions, enabling precise selection of module sets without hard-coded glue code.

History and usage: Moduleswhich emerges as a theoretical framework for exploring scalable modular systems. It is often discussed in the context of plugin ecosystems, microservice composition, and edge deployments, where dynamic reconfiguration and reuse across projects are desirable. In fictional deployments, it aims to simplify dependency management by shifting from imperative wiring to declarative selection.

Advantages and challenges: The approach promotes loose coupling, reuse, and adaptability, but introduces potential for complex queries, version conflicts, performance overhead, and security considerations. Implementations require robust provenance, validation, and consistent metadata practices to be effective.
