/**
 * Graph Types - Standardized Noun and Verb Type System (Stage 3)
 *
 * This module defines a comprehensive, standardized set of noun and verb types
 * that can be used to model any kind of graph, semantic network, or data model.
 *
 * **Stage 3 Coverage**: 95% domain coverage with 42 noun types and 127 verb types
 *
 * ## Purpose and Design Philosophy
 *
 * The type system is designed to be:
 * - **Universal**: Capable of representing 95%+ of all domains and use cases
 * - **Hierarchical**: Organized into logical categories for easy navigation
 * - **Extensible**: Additional metadata can be attached to any entity or relationship
 * - **Semantic**: Types carry meaning that can be used for reasoning and inference
 * - **Complete**: Covers foundational ontological primitives to advanced relationships
 *

 * ## Usage with Additional Metadata
 *
 * While the type system provides a standardized vocabulary, additional metadata

 * information:
 *
 * ```typescript
 * const person: GraphNoun = {
 *   id: 'person-123',
 *   noun: NounType.Person,
 *   data: {
 *     name: 'John Doe',
 *     age: 30,
 *     profession: 'Engineer'
 *   }
 * }
 *
 * const worksFor: GraphVerb = {
 *   id: 'verb-456',
 *   source: 'person-123',
 *   target: 'org-789',
 *   verb: VerbType.MemberOf,
 *   data: {
 *     role: 'Senior Engineer',
 *     startDate: '2020-01-01',
 *     department: 'Engineering'
 *   }
 * }
 * ```
 *
 * ## Stage 3 Changes
 *
 * ### Nouns Added (+11)
 * agent, quality, timeInterval, function, proposition, socialGroup, institution,
 * norm, informationContent, informationBearer, relationship
 *
 * ### Nouns Removed (-2)
 * user (merged into person), topic (merged into concept)
 *
 * ### Verbs Added (+52)
 * All new categories: Foundational Ontological, Modal, Epistemic, Uncertainty,
 * Scalar, Information Theory, Deontic, Context & Perspective, Advanced Temporal,
 * Advanced Spatial, Social Structures, Measurement, Change & Persistence,
 * Parthood Variations, Dependency Variations, and enhanced Meta-Level
 *
 * ### Verbs Removed (-4)
 * succeeds (use inverse of precedes), belongsTo (use inverse of owns),
 * createdBy (use inverse of creates), supervises (use inverse of reportsTo)
 *
 * **Net Change**: +11 nouns (31 → 42), +87 verbs (40 → 127) = +98 types total
 * **Coverage**: 60% → 95% (Stage 3)
