Provenance API

Records every transformation, aggregation, and enrichment event as an append-only, cryptographically chained log. This creates a tamper-evident audit trail from raw data ingestion to final training corpus inclusion.

• Uses content-addressed storage (e.g., SHA-256 hashing) to uniquely identify each data version.
• Prevents retroactive alteration of provenance records, satisfying SOC 2 and GDPR audit requirements.

Generates a unique, compact digital signature for a dataset using perceptual or cryptographic hashing algorithms. This fingerprint serves as the asset's verifiable identity.

• Enables detection of unauthorized duplication or modification.
• Allows verification that a Training Corpus Manifest accurately references the exact data version used.

Structures provenance metadata according to the W3C PROV standard, representing entities, activities, and agents. This ensures interoperability across different governance and compliance platforms.

• Exports provenance graphs as PROV-O (OWL2 ontology) or PROV-JSON.
• Enables standardized querying of data responsibility and derivation chains.

Provides a dedicated endpoint to programmatically validate that a data asset's current usage complies with its associated Rights Expression Language (REL) license.

• Checks for revocation events or expired consent windows before authorizing data access.
• Integrates with an Entitlement Service to make real-time policy decisions.

Allows users to query provenance graphs at the column, row, or record level, not just at the dataset level. This is critical for debugging model bias or tracing a specific error back to its source.

• Supports graph traversal queries to find all downstream assets derived from a problematic data point.
• Essential for executing precise Model Unlearning Requests.

Seamlessly integrates with data version control systems like DVC or LakeFS to automatically capture provenance events during standard data engineering workflows.

• Automates the creation of a Dataset Fingerprint on every commit.
• Bridges the gap between MLOps pipelines and governance reporting dashboards.

A unique, compact digital signature generated from a dataset's content using cryptographic hashing (like SHA-256) or perceptual algorithms. A Provenance API queries this fingerprint to verify that a dataset has not been tampered with since its creation. Any modification, even a single bit flip, produces a completely different hash, ensuring tamper-proof integrity verification.

A structured, machine-readable document detailing the composition, provenance, and licensing terms of all datasets included in a specific AI model's training data package. A Provenance API consumes this manifest to automate compliance auditing.

• Lists all constituent datasets by unique identifier
• Declares licensing terms and usage restrictions
• Provides cryptographic hashes for integrity checks

A standardized, structured transparency document accompanying a dataset that describes its intended use, composition, collection process, and licensing restrictions. Provenance APIs use data cards as a machine-readable source of truth for automated rights verification before granting ingestion access to model training pipelines.

A persistent, unique alphanumeric string registered through a central authority (like Crossref or DataCite) to permanently identify and link to a specific digital content object. A Provenance API resolves DOIs to establish a canonical, citable reference for data assets, ensuring that attribution chains remain unbroken even if the asset's physical location changes.

A machine-readable language for specifying permissions, constraints, and obligations governing the use of digital content. Standards like ODRL and CC REL are parsed by Provenance APIs to programmatically determine if a specific use case—such as commercial AI training—is permitted under the asset's declared license.

A programmatic interface enabling automated negotiation, execution, and management of rights grants for AI training data ingestion. It works in tandem with a Provenance API: the licensing API handles the transaction, while the provenance API verifies the asset's lineage and authenticity before any rights are granted.
