ProvenanceTracking

ProvenanceTracking is the practice and set of technologies used to capture, store, and interpret the history of data, artifacts, and processes. It records origins, transformations, custody, and decision points, enabling users to understand how a result was produced and by whom. The concept is applied across domains such as data science, software development, manufacturing, and scientific research to support reproducibility, accountability, and quality assurance.

A provenance model typically represents entities, activities, and agents and the relationships among them. Provenance capture can occur at source via instrumentation, through log aggregation, or by attaching metadata to outputs. Provenance data is often stored in graph- or document-oriented stores and exposed via query interfaces and visualizations that show lineage, impact, and dependencies. Standards such as the W3C PROV family (PROV-DM, PROV-O) provide common schemas for describing provenance information; formats like PROV-JSON or PROV-XML are used to exchange data between systems.

Use cases include tracing the lineage of a data set, auditing machine learning model training pipelines, verifying the integrity of supply chains, and supporting audit trails for compliance. Benefits include improved reproducibility, transparency, and trust; however, challenges include handling large-scale provenance data, protecting sensitive information, interoperability between heterogeneous systems, and the potential performance overhead of capturing provenance.
