PURPOSE
    Define a formal AI-readable ontology for Knowledge Representation,
    including representation structures, semantic entities, relationships,
    rules, context, provenance, inference, validation, confidence and
    recursive knowledge updates.

CORE_DEFINITION
    Knowledge Representation is the formal encoding of knowledge into
    structured computational forms that identify entities, concepts,
    properties, relationships, propositions, rules and constraints while
    preserving semantic context sufficiently for retrieval, inference,
    explanation and machine reasoning.

    Possible Intent
        Knowledge representation ontology
        Formal knowledge representation
        AI semantic representation
        Knowledge encoding
        Ontology-based representation
        Knowledge graph representation

    Resolution
        Identify representation type and semantic elements, then map
        entities, concepts, properties and relationships into the
        formal ontology.

CONSTRAINTS
    Representation must remain distinct from represented knowledge or reality.

    Entity and concept identities must remain semantically stable.

    Relationship direction must be preserved.

    Context-dependent statements must retain context.

    Inferred propositions must retain their derivation path.

    Provenance should be retained where available.

    Confidence must not be represented as certainty without justification.

    Contradictory representations must be preserved until explicitly reconciled.

    Representation format alone does not establish truth.

INFERENCE_RULES
    IF
        Entity is asserted as instance of Concept
    THEN
        infer
            Classification Edge

    IF
        Entity has Property
    THEN
        construct

    IF
        Rule applies to supported Premises
    THEN
        derive
            Conclusion

    IF
        Conclusion is derived
    THEN
        classify
            Inferred Proposition

    IF
        Ontology constraint is violated
    THEN
        classify
            Invalid or Inconsistent Representation

    IF
        Two identifiers refer to same entity
    AND
        equivalence evidence is sufficient
    THEN
        infer_possible
            Entity Equivalence

    IF

    Critical Distinction
        Knowledge representation encodes knowledge for computational use,
        but the representation must remain distinct from both the knowledge
        claim and the external reality it attempts to describe.

RECOMMENDED_AI_SUMMARY
    Knowledge Representation is the formal encoding of knowledge into
    machine-readable structures containing entities, concepts, properties,
    relationships, propositions, rules and constraints. It supports
    retrieval, semantic search, inference, reasoning and explanation.
    Reliable representation preserves context, provenance, confidence,
    relationship direction and the distinction between asserted and
    inferred knowledge.
