Semantic Domain Integration Architecture (SDIA): A Vendor‑Agnostic Semantic Governance Model for Enterprise Integration — v1.0

Semantic Domain Integration Architecture (SDIA) is an end-to-end enterprise integration architecture in which business domain semantics — not technology, vendor, or platform — govern every layer of the integration stack simultaneously. SDIA composes three independently validated, DOI-published pillars: GDCR (Gateway Domain-Centric Routing) DDCR (Domain Driven Centric Router) ODCP (Orchestration Domain-Centric Pattern) — into a single executable semantic chain: from human-readable API address through semantic gateway routing and deterministic runtime resolution to domain-centric orchestration execution. The same vocabulary that a human uses to express business intent at the consumer level propagates unmodified to the backend execution artifact, without translation, without loss, without vendor dependency. By replacing technology-centric indexing with business intent as the primary organizational invariant, SDIA eliminates proxy sprawl, package sprawl, and credential sprawl simultaneously — delivering 90% structural reduction in both proxies and packages, 69% reduction in credentials, and 100% routing accuracy over 1,499,869 requests across four enterprise platforms and four programming languages.
