Canonical Knowledge Structures (CKS): Core Theoretical Specifications (Version 1.2)

This publication contains the complete first-generation Core specifications of the Canonical Knowledge Structures (CKS) project, together with the first reference implementation specification.

Together, these documents establish the implementation-independent theoretical foundation and the first normative implementation of Canonical Knowledge Structures, including:

• CKS‑000 — Canonical Foundations and Terminology (Foundational Manifesto, Architecture Map, unified glossary)

• CKS‑001 — Core Specification (formal semantic model)

• CKS‑002 — Canonical Construction Specification

• CKS‑003 — Canonical Serialization

• CKS‑004 — Canonical Structure Evolution

• CKS‑005 — Validator Specification

• CKS‑006 — Reference Engine Specification

• CKS‑007 — Canonical Knowledge Interface (CKI)

• CKS‑008 — Reference Conformance Specification

• CKS‑B001‑PY — Python Reference Implementation (normative public API)

The Core defines the philosophical foundations, formal semantic model, construction principles, serialization model, admissible evolution, canonical validation, reference computation, interaction interface, and unified conformance criteria for Canonical Knowledge Structures.

The Python Reference Implementation provides the first executable realisation of the CKS validation model and Reference Engine, establishing a normative public API for conformant implementations.

The specifications are intended to serve as the stable theoretical and practical basis for subsequent CKS documents, including validation, canonicalization, reasoning, implementation technologies, and future extensions.

Changes in Version 1.2. This revision updates three Core specifications: CKS‑000 (Canonical Foundations and Terminology), CKS‑008 (Reference Conformance Specification), and CKS‑B001‑PY (Python Reference Implementation). The updates introduce additional foundational principles, strengthen the conformance criteria, and refine the Python Reference API to serve as the behavioural reference for future language bindings.
