DominiCommon

DominiCommon is an open‑source software library that provides a set of shared domain-driven design primitives intended to be used across applications. It delivers core abstractions for entities, value objects, aggregates, domain events, and repositories, along with cross-cutting concerns such as validation, auditing, localization, and identity generation. The goal is to decouple domain logic from infrastructure and to enable consistent domain modeling across projects.

Its architecture is modular and language-agnostic, employing a core domain layer separated from adapters to persistence, messaging, and UI. The library defines invariants, equality semantics, and lifecycle semantics for domain objects, while optional modules supply validation rules, event publishing, and auditing. Emphasis is placed on testability and deterministic behavior.

DominiCommon originated from a community effort to standardize reusable domain logic and to facilitate collaboration across teams. It is released under the MIT license and is maintained by an open contributor base, with governance that emphasizes backward compatibility and semantic versioning.

Usage typically involves building domain models within backend services or microservices, and then integrating them with persistence and messaging via adapters. The library supports various persistence backends through adapter implementations and can be combined with application services to orchestrate use cases without leaking infrastructure concerns into the domain.

Reception in the software development community is mixed: proponents credit the library with promoting consistent domain modeling and faster onboarding, while critics note that it is not a drop‑in full framework and may require additional architecture guidance and discipline to use effectively.
