Unified Semantic Fabric

Every platform accumulates local semantics: this mart's definition of "customer", that pipeline's notion of "active", a third team's version of "revenue". A unified semantic fabric is the architectural counter-move — a single connected layer of concepts, relationships, and definitions that spans sources and domains, so that meaning is resolved once and referenced everywhere. "Fabric" is deliberate: not a monolithic central model that one team owns, but a woven network where domain models connect through shared concepts — the enterprise ontology provides the shared vocabulary, and something like a metadata mesh provides the distribution model. Domains keep autonomy over their detail; the fabric guarantees that where their concepts touch, they agree. In MDDE terms the fabric is not documentation — it is input. Because integration layers, exposure views, and lineage are generated from the semantic layer, consistency is not a review outcome but a structural property: two artifacts derived from the same fabric cannot silently disagree about what a customer is. This is the architecture-scale expression of what semantic design does at model scale.
