The protocol-layer position for standardized lineage exchange in AI and data systems.

A protocol framing for lineage on .ai — the canonical coordinate for the emerging standard that systems use to communicate provenance.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

Protocols define how systems talk to each other. For lineage to function across heterogeneous data estates and multi-vendor AI stacks, a shared protocol is required. On .ai, this string claims the position for whoever standardizes that exchange — the most structurally defensible coordinate in the lineage cluster.

Where it fits

A few directions this coordinate opens —

Open lineage standard
The namespace for a shared protocol that allows any data system to emit and consume lineage records in a standard format.
Open-source foundations, data infrastructure vendors building interoperable tooling
Agent-to-agent provenance exchange
A protocol for AI agents to communicate and verify provenance claims when passing data or decisions between systems.
Agentic AI platform builders, multi-agent coordination infrastructure vendors

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
