Spine
The protocol that lets data trade without leaving home.
Spine is the cross-system protocol: the layer that makes data from any participating system discoverable, queryable, and exchangeable, without the data ever leaving the system that owns it. It is the gate between systems and the plumbing of the market.
The mechanics are continuous with what happens inside a single app. The same three modules (Store, Query, Channels) govern sharing within an app (where Frame implements them) and across apps (where Spine extends them over system boundaries). The principles do not change at the boundary; only the scope does. That is what keeps custody intact end-to-end: querying across the ecosystem is the same sovereignty model as sharing inside one app.
Spine is deliberately designed for participants that were never built on Frame. A government registry, an NGO database, or a traceability platform can publish to or subscribe from Spine. Anyone can build a protocol; Spine is worth using because of the supply already flowing through it.
Where it sits. Stands on the shared conventions at cross-system scope. Sibling to Scribe; independent of Frame and Forge.
- 01StoreWhere data + permissions live
Own and acquired data, and the gateway from an app’s custom subjects to canonical DAAC subjects.
- 02QueryDiscover across boundaries
Ask which systems hold data on a subject; identification and lineage return, content never moves.
- 03ChannelsPermissioned exchange
Signed, lineage-bearing assertions; sharing settings travel, and can only be tightened downstream.
Frame runs these inside an app; Spine extends the same contracts across systems. Data stays at source, Spine holds metadata, routes and permissions, never the records.
registered, key-holding systems in the ecosystem
one query, every source
the direct expression of cross-boundary reach
true by design, Spine holds metadata only
each exchange appends one signed licensing entry
Metrics are deferred to a later version; v0 emits structured logs only. “Records stay at source” is architectural, not a counter. No live figures exist, none are shown.
- Digital system development and maintenanceA described situation becomes a system people work in, and it stays in step with what it was built on instead of drifting behind it.
- Targeted knowledge discoveryA local data supply reaches the markets that want it: discoverable, permissioned and payable at the holder’s own discretion, with nobody taking custody of it to make that true.
