Domaincompatible

Domaincompatible is a term used to describe data, interfaces, or functions that conform to the constraints of a defined domain. The domain represents the contexts and rules within which a system operates. Maintaining domaincompatibility helps ensure interoperability and correctness across system boundaries.

In mathematics and theoretical computer science, domaincompatible data or functions accept inputs only from the specified domain and adhere to its invariants; such compatibility keeps operations well-defined and safe.

In software engineering and data integration, domaincompatible interfaces and schemas align with the domain model, including terminology, units, and validation rules. This alignment reduces mapping complexity and errors when composing disparate systems.

Examples include a domaincompatible date type that uses a specified calendar, time zone, and valid range, or a domaincompatible API that expects values in a given currency and locale. In domain-driven design, modules tied to a bounded context are described as domaincompatible with that context.

Although widely intelligible, domaincompatible is not a formal standard term and its precise meaning varies by field and project. When used, it should be defined within the relevant context. Related concepts include domain-driven design, API compatibility, and interoperability.
