Sovereign meaning, one shared form.
Vercy describes any domain as Dimensions, Namespaces, Objects, Projections and Events: a common language for composing meta-models across organizations, products and states. You conform to the shared structural form; you keep your domain meaning, your data and the right to leave with both.
Meaning doesn't travel between systems.
Every product, organization and domain models the world in its own way. That knowledge lives in silos, so meaning breaks at every boundary and every integration is bespoke and brittle. Vercy is an open standard that lets independent models interoperate by sharing one structural form, how a unit of meaning is built, not one schema, what your terms mean. The form is required; the vocabulary is not.
Without a shared standard
N×N custom integrations · schemas drift · meaning is lost in translation · AI agents can't reason across systems.
With Vercy
Each model keeps its own vocabulary; the price is conforming to one shared form · you map once to that form · knowledge flows as Projections a validator can check · the same graph reads for humans and AI.
Six ideas describe any domain.
Vercy is small on purpose. A handful of nested primitives can express a product, an enterprise, or an entire state, and they compose the same way everywhere.
One owner's world of meaning. Sovereign means: you set the domain rules, you can fork the shared form, and you can leave with your models under an open license. Conforming to the form is the standing condition.
A management context inside a Universe: one coherent area of the model: a domain, a landscape, a state.
The unit of publication and discovery: a named, versioned meta-model others can reference.
A point of truth: a modelled thing, with its properties and relationships.
A shared view of an Object across a boundary. Ownership stays home because a Projection is a view under a Contract, not a copy; the boundary is enforced by the projection rules, not by trust.
A change on the semantic timeline: how meaning evolves, traceably, over time.
Sovereign models, one shared form.
Three moves take a model from isolated to interoperable.
Model
Describe your domain in Vercy primitives. You keep ownership, versioning and governance of the content. One thing is centralized on purpose: the structural form, minimal and shared, like a shipping container fixes dimensions but not cargo.
Compose
Reuse what the world already standardized. Bind fields to a registry of 1,180 external standards (embed an address, reference a currency, mix in provenance) instead of re-inventing them.
Federate
Map your meaning to a shared canonical reference and exchange Projections a validator can check. Two Projections that share a Semantic Fingerprint, over the canonical form and never a byte hash, carry identical canonical structure; that does not prove two domains agree on meaning, which is asserted by Contract.
Three pillars.
Constitution
The rules every participant must honor to interoperate: the shared form, provenance and traceability. This is the mandatory layer; the registry CI refuses models that break it.
Architecture
How a meta-model is built, versioned, validated, composed and packaged.
Federation
How sovereign Universes exchange meaning: identity binding, contracts, mapping, trust.
Made for people and for machines.
For people
Plain-language docs, guided tutorials and courses: from your first Dimension to a federated model. Multilingual.
For AI
Every page has a machine-readable twin: llms.txt, a spec index, JSON schemas and content fingerprints, so agents can read, reason over and implement the standard directly.
