# ConstructOntology

Building a structured conceptual framework

Layer: Mind · Category: Reasoning

## Mechanism

A primitive for building a structured set of concepts and relationships (an ontology) from raw data or seed axioms. It defines the 'physics' or 'rules' of a domain. This is the primitive itself, not a methodology for applying it. It builds the semantic graph from [FirstPrinciples](https://mindscape.pages.dev/bootstrap/FirstPrinciples.md), validating edge coherence via [AdversarialSteel](https://mindscape.pages.dev/bootstrap/AdversarialSteel.md) and establishing shared context through [OntologyHandshake](https://mindscape.pages.dev/bootstrap/OntologyHandshake.md).

## Invariants

- Every referenced term is defined.
- No contradictions within the ontology.
- Grounded in [FirstPrinciples](https://mindscape.pages.dev/bootstrap/FirstPrinciples.md) rather than in borrowed vocabulary.

## Preconditions

- Seed concepts or data available

## Postconditions

- Valid ontology object created

## Failure modes

- Incoherence: Contradictory axioms or definitions.

## Parameters

- `depth` (Integer, [1, 10]): Hierarchical depth
- `format` (Enum, {OWL, JSON-LD, Sema}): Output format
