Canonical RDomain Structure

Canonical structure governing how each RDomain declares its identity, scope, entities, relationships, state, evidence, traversal behavior and extension discipline.

The RDomain structure is not a replacement for shared Athena engines. It is a governed domain declaration layer that specifies how a domain specializes the common substrate while remaining interoperable, traversable and verifiable.

Canonical Profiles

Governance Objective

Consistency

Extension Principle

Additive

Compatibility Basis

Shared Engines

Canonical Structure Stack

Logical dependency order from domain identity to additive extensions.

Governance Balance

A healthy RDomain balances semantics, evidence, traversal and extension discipline.

Canonical Pages

Domain Identity

Stable identifier, naming, versioning, ownership and lifecycle governance.

Semantic Scope

Classes, predicates, constraints, vocabularies and controlled domain extensions.

Entity Profiles

Canonical node classes, identity keys and resolution rules.

Relationship Profiles

Typed links, directionality, context and inverse semantics.

State / Temporal Profiles

State machines and temporal specialization on the shared substrate.

Evidence Profiles

Admissible source classes, provenance and verification obligations.

Traversal Profiles

Depth, predicate policy, temporal filtering and epistemic traversal rules.

Extension Contracts

Versioned additive contracts that preserve core engine compatibility.

Implementation Guidance

Profile	What it must define	What it must not do
Domain Identity	Uniqueness, ownership, version and lifecycle state.	Change entity semantics implicitly.
Semantic Scope	Meaning boundaries, classes, predicates and constraints.	Permit uncontrolled vocabulary drift.
Entity Profiles	Node classes, keys, aliases and resolution logic.	Use ad hoc identifiers without canonicalization.
Relationship Profiles	Link types, context, cardinality and inverses.	Create semantically ambiguous edges.
State / Temporal	States, transitions and temporal anchoring.	Invent disconnected time logic outside the shared substrate.
Evidence Profiles	Admissibility, provenance and verification thresholds.	Treat all sources as epistemically equal.
Traversal Profiles	Safe navigation rules, filters and blocked routes.	Allow unrestricted graph walks by default.
Extension Contracts	Additive versioning, compatibility and declared dependencies.	Override or replace the shared engines.
