projectdomainfeaturev2

projectdomainfeaturev2 is a modular framework within the Project Domain software ecosystem that manages domain-specific features across distributed services. It provides a standardized feature representation, domain boundary enforcement, and secure orchestration of cross-domain feature processing for multi-tenant environments. The v2 release builds on the original design by introducing tighter isolation, refined APIs, and enhanced observability.

Core components include a domain feature model that defines the shape and semantics of features, a feature registry for discovery and versioning, a domain boundary policy that enforces access controls, transport adapters that integrate with various messaging and service buses, and an API surface for publishers and consumers to interact with features.

The architecture consists of a client SDK that applications embed, a server-side feature service that stores and validates feature definitions, and a messaging layer that enables asynchronous propagation across services. It supports multiple transport protocols and provides validation hooks, lineage tracking, and audit logs.

Version 2 introduces improved performance and scalability through parallel feature evaluation, better isolation between domains, stronger privacy controls, and richer observability through metrics and traces. It also includes enhanced tooling for schema evolution and backward-compatible migrations from version 1.

Deployment considerations include cloud and on-premises deployments, containerized runtimes, and required platform libraries. Migration from projectdomainfeaturev1 is guided by a staged upgrade process that preserves feature definitions and avoids breaking changes where possible.
