Formatdriven

Formatdriven is a conceptual approach in software engineering and data processing in which the explicit formats and schemas of data drive the design, validation, and transformation of systems.

In practice, formatdriven emphasizes defining data contracts and formats early, using schemas and interface definitions to guide implementation. Systems rely on these contracts to parse, validate, and route data, while keeping processing logic decoupled from representation.

Common tools include JSON Schema, XML Schema, or YAML-based schemas, and code generation practices that produce data models, validators, and adapters from the format definitions.

Applications span data ingestion pipelines, multi-format document rendering, API design with client generation, and reporting systems that must output several formats such as JSON, XML, HTML, or PDF from the same source.

Advantages include stronger data validation, easier interoperability, clearer governance of data contracts, and the ability to adapt to new formats with less change to business logic.

Challenges involve tooling complexity, schema drift, versioning of contracts, potential performance overhead, and the need for discipline to avoid over-matching formats to behavior.

Formatdriven shares ideas with data-driven development, schema-driven engineering, and contract testing, while complementing model-driven and API-first approaches.
