⍝ Find pattern relationships
connected ← GetAllConnectedPatterns 1

Features:

• ✨ 253 patterns as array-based data structures
• 🔍 Fast array-based queries and filters
• 🔄 Domain transformations (physical/social/conceptual/psychic)
• 🔗 Relationship navigation and path finding

🔄 Meta-Recursive Organization

Patterns Applied to Repository Structure:

This repository uses Pattern Language principles to organize itself:

Navigation & Access

• PATTERN_MAP.md - 8 independent regions (Pattern 1: Independent Regions)
• NAVIGATION_HUB.md - Multiple entry points (Pattern 28: Eccentric Nucleus)
• SEQUENCE_NAVIGATION.md - Navigate 36 sequences (Pattern 52: Network of Paths)
• PATTERN_INDEX.md - Complete access (Pattern 30: Activity Nodes)

Integration & Understanding

• PATTERN_CROSS_REFERENCE.md - Links between APL/UIA/Archetypal (Pattern 8: Mosaic of Subcultures)
• META_RECURSIVE_IMPLEMENTATION.md - Complete analysis of self-application
• .github/copilot-instructions.md - GitHub Copilot guidance using Pattern Language principles

Cognitive Achievement

• ✅ Multi-scale perception: Navigate repository → region → sequence → pattern
• ✅ Relationship richness: Clear connections between all elements
• ✅ Contextual relevance: Find patterns by domain/context/need
• ✅ Gestalt perception: See the whole as living system
• ✅ Optimal grip: Structure supports understanding

The repository is both documentation of patterns and example of patterns in use.

Markdown Versions

The markdown/ directory contains converted versions of all APL and UIA pages in markdown format for improved readability and accessibility:

• markdown/apl/: 253 A Pattern Language patterns (apl001.md - apl253.md)
• markdown/uia/: 253 UIA Patterns & Metaphors (12610010.md - 12612530.md)

See markdown/README.md for detailed information about the conversion process and markdown structure.

Pattern Language Schema

The repository includes formalized JSON schemas for both the Pattern Language and Archetypal Patterns:

APL Pattern Language Schema

• Pattern Language Schema (pattern_language_generated.json) - Complete meta-pattern, categories, and sequences
• Pattern Sequences (pattern_sequences.json) - All 36 pattern sequences with emergent phenomena
• Categories (category_*.json) - Towns, Buildings, and Construction categories

See PATTERN_SCHEMA_README.md for detailed information about the APL schema structure.

Archetypal Pattern Schema

• Archetypal Pattern Schema (archetypal_pattern_schema.json) - JSON schema for archetypal patterns
• Archetypal Patterns (archetypal_patterns.json) - All 102 archetypal patterns with domain mappings
• Placeholder Reference (archetypal_placeholders.json) - Complete placeholder documentation

Archetypal patterns use the format: "generic {{domain-specific}} generic" and can be transformed across:

• Physical - Spatial, material, architectural domains
• Social - Organizational, community, institutional domains
• Conceptual - Knowledge, theoretical, paradigmatic domains
• Psychic - Awareness, consciousness, mental domains

See ARCHETYPAL_SCHEMA_README.md for detailed information about the archetypal pattern schema.

OpenCog Atomese Representation

The Pattern Language has been converted to OpenCog's Atomese format for knowledge representation and pattern matching:

• opencog_atomese/ - Complete Atomese hypergraph representation in Scheme format
  • pattern_language.scm - Complete representation
  • meta_pattern.scm - Meta-pattern
  • categories.scm - Categories with InheritanceLinks
  • sequences.scm - Sequences with MemberLinks
  • Enhanced Features:
    • pattern_language_enhanced.scm - Enhanced with diagrams, details, and connections
    • relationship_types.scm - Pattern relationship types (complement, conflict, alternative)
    • patterns/ - Individual .scm files for modular loading

The Atomese format enables:

• Pattern matching and reasoning in OpenCog
• Hypergraph queries for pattern relationships
• Knowledge graph navigation and inference
• Integration with AI/AGI systems

See opencog_atomese/README.md for usage examples and opencog_atomese/ENHANCEMENTS.md for enhanced features documentation.

Paradigm & Language Analysis

Comprehensive analysis of optimal implementation approaches for achieving cognitive "optimal grip" on the gestalt salience landscape:

• PARADIGM_LANGUAGE_ANALYSIS.md - Complete paradigm and language evaluation

  • Analysis of 6 programming paradigms (hypergraph, functional, logic, OOP, constraint, agent-based)
  • Evaluation of 6+ languages (Scheme, Datalog, Python, Haskell, JavaScript, Prolog)
  • Cognitive affordances mapping
  • Recommended multi-layer architecture

• IMPLEMENTATION_GUIDE.md - Practical implementation guide

  • Concrete code examples for each layer
  • Datalog query system integration
  • Haskell domain transformation engine
