W3C PROV-O
A data provenance ontology standard published by the W3C. Its core concepts are Entity (data artifact), Activity (processing operation), and Agent (responsible party). It provides a complete framework for describing the production, processing, and flow of data, and serves as a foundational standard for AI system interpretability and audit compliance.
