requiere

Requiere is a fictional open‑source framework designed to model, trace, and verify software requirements and their relationships to code and tests. It provides a declarative language for detailing requirements, constraints, and acceptance criteria, along with tools to check consistency, generate documentation, and visualize dependencies. The project is used as a teaching example and as a lightweight approach to requirements traceability.

History: Requiere emerged from a collaboration of developers and researchers in 2016, with an open‑source release in 2017. From 2018 to 2020, community contributions created a modular ecosystem, including a core engine, a browser studio, and server components. It remains a demonstration project rather than a mainstream product.

Design and features: The core uses a declarative language for specifying requirements, links to code artifacts and tests, and validation rules. A graph model provides bidirectional traceability between elements and versions. Features include baseline management, impact analysis, quality gates, and a plugin architecture. Tooling includes a CLI, a web UI, and API access, with adapters for common issue trackers and version control systems.

Architecture: Requiere comprises a language parser, a graph store, a rule evaluator, and modular adapters. The engine runs as a standalone service or embedded library. Extensions enable integration with GitHub, Jira, and CI systems, with the UI connecting to multiple repositories via a lightweight server.

Reception: In academic settings, Requiere is cited for clarifying requirement traceability. Critics note a learning curve and limited real‑world adoption outside education, though the concepts have influenced other requirements management tools.
