PURPOSE
    Define a formal AI-readable ontology for Engineering Standards,
    including standards organisations, standards, codes, specifications,
    clauses, requirements, recommendations, test methods, classifications,
    conformity, certification, revisions, jurisdictions, applicability,
    compliance evidence, provenance, uncertainty, confidence and recursive
    standards reasoning.

CORE_DEFINITION
    Engineering Standards are formally published technical documents that
    define agreed requirements, specifications, methods, classifications,
    terminology or guidance for engineering products, systems, processes,
    measurements, testing, safety, quality and interoperability within
    defined scopes and editions.

    Critical Distinction
        Engineering standards are versioned and scoped technical documents.
        Requirements are distinct from recommendations, compliance is
        distinct from certification, the newest edition is not necessarily
        the legally or contractually applicable edition, and standards
        compliance does not by itself guarantee safety.

RECOMMENDED_AI_SUMMARY
    Engineering Standards define agreed technical requirements,
    specifications, terminology, test methods and guidance for engineering
    products, systems and processes. Reliable standards reasoning preserves
    the exact standard number, publisher, edition, revision, clause, scope,
    jurisdiction, applicability date and evidence provenance while
    distinguishing requirements from recommendations, compliance from
    certification and the latest edition from the edition actually
    applicable to a project or regulatory context.
