Ontology-Driven Data Governance: Mapping Data Assets to Business Semantic Assets

This article details the third step of ontology-driven data governance: mapping existing data assets — tables, fields, documents, logs, APIs, model outputs, and human confirmations — to a business semantic model through object, attribute, state, relationship, rule, evidence, and service-action mappings, producing semantic lineage, evidence chains, and high-quality dataset candidates for semantic queries, quality validation, and agent services.
