ancestor-descendant relationships: + +```sql +-- Example: Technology → Programming → Web Development → React +-- Direct relationships: +INSERT INTO tag_relationships VALUES (1, 2, 'parent_child', 1.0); -- Tech → Programming +INSERT INTO tag_relationships VALUES (2, 3, 'parent_child', 1.0); -- Programming → Web Dev +INSERT INTO tag_relationships VALUES (3, 4, 'parent_child', 1.0); -- Web Dev → React + +-- Closure table automatically maintains all paths: +INSERT INTO tag_closure VALUES (1, 1, 0, 1.0); -- Tech → Tech (self) +INSERT INTO tag_closure VALUES (1, 2, 1, 1.0); -- Tech → Programming +INSERT INTO tag_closure VALUES (1, 3, 2, 1.0); -- Tech → Web Dev (via Programming) +INSERT INTO tag_closure VALUES (1, 4, 3, 1.0); -- Tech → React (via Programming, Web Dev) +-- ... and so on for all relationships +``` + +This enables efficient queries like "find all content tagged with any descendant of Technology": + +```sql +SELECT DISTINCT e.* +FROM entries e +JOIN user_metadata_semantic_tags umst ON e.metadata_id = umst.user_metadata_id +JOIN tag_closure tc ON umst.tag_id = tc.descendant_id +WHERE tc.ancestor_id = (SELECT id FROM semantic_tags WHERE canonical_name = 'Technology'); +``` + +## Key Features + +### 1. Polymorphic Naming + +Multiple tags can share the same canonical name when differentiated by namespace: + +```rust +// Same name, different contexts +let phoenix_city = SemanticTag { + canonical_name: "Phoenix".to_string(), + namespace: Some("Geography".to_string()), + description: Some("City in Arizona, USA".to_string()), + // ... +}; + +let phoenix_myth = SemanticTag { + canonical_name: "Phoenix".to_string(), + namespace: Some("Mythology".to_string()), + description: Some("Mythical bird that rises from ashes".to_string()), + // ... +}; +``` + +This allows natural, human-friendly naming without forcing artificial uniqueness. + +### 2. Semantic Variants + +Each tag supports multiple access points for flexible user interaction: + +```rust +let js_tag = SemanticTag { + canonical_name: "JavaScript".to_string(), + formal_name: Some("JavaScript Programming Language".to_string()), + abbreviation: Some("JS".to_string()), + aliases: vec!["ECMAScript".to_string(), "ES".to_string()], + namespace: Some("Technology".to_string()), + // ... +}; + +// All of these resolve to the same tag: +assert!(js_tag.matches_name("JavaScript")); +assert!(js_tag.matches_name("js")); // Case insensitive +assert!(js_tag.matches_name("ECMAScript")); +assert!(js_tag.matches_name("JavaScript Programming Language")); +``` + +### 3. Context-Aware Resolution + +When users type ambiguous tag names, the system intelligently resolves them based on existing context: + +```rust +// User is working with geographic data and types "Phoenix" +let context_tags = vec![arizona_tag, usa_tag, city_tag]; +let resolved = tag_resolver.resolve_ambiguous_tag("Phoenix", &context_tags).await?; +// Returns "Geography::Phoenix" (city) rather than "Mythology::Phoenix" (bird) +``` + +The resolution considers: +- **Namespace compatibility** with existing tags +- **Usage patterns** from historical co-occurrence +- **Hierarchical relationships** between tags + +### 4. Hierarchical Organization + +Tags form a directed acyclic graph (DAG) structure supporting: + +``` +Technology +├── Programming +│ ├── Web Development +│ │ ├── Frontend +│ │ │ ├── React +│ │ │ └── Vue +│ │ └── Backend +│ │ ├── Node.js +│ │ └── Python +│ └── Mobile Development +│ ├── iOS +│ └── Android +└── Design + ├── UI/UX + └── Graphic Design +``` + +Benefits of hierarchical organization: +- **Implicit Classification**: Tagging with "React" automatically inherits "Frontend", "Web Development", etc. +- **Semantic Discovery**: Searching "Technology" surfaces all descendant content +- **Emergent Patterns**: System reveals organizational connections users didn't explicitly create + +### 5. AI Integration + +The system supports AI-powered tagging with confidence scoring: + +```rust +// AI analyzes image and applies tags +let ai_application = TagApplication { + tag_id: vacation_tag_id, + applied_context: Some("image_analysis".to_string()), + confidence: 0.92, + source: TagSource::AI, + instance_attributes: hashmap! { + "detected_objects".to_string() => json!(["dog", "beach", "sunset"]), + "model_version".to_string() => json!("v2.1") + }, + // ... +}; +``` + +AI features: +- **Confidence Scoring**: 0.0-1.0 confidence levels for AI suggestions +- **User Review**: Low confidence tags require user approval +- **Learning Loop**: User corrections improve future AI suggestions +- **Privacy Options**: Local models (Ollama) or cloud APIs with user control + +### 6. Union Merge Conflict Resolution + +During synchronization, tag conflicts are resolved using an additive approach: + +```rust +// Device A: Photo tagged with "vacation" +let local_apps = vec![TagApplication::user_applied(vacation_tag_id, device_a)]; + +// Device B: Same photo tagged with "family" +let remote_apps = vec![TagApplication::user_applied(family_tag_id, device_b)]; + +// Union merge result: Photo tagged with BOTH "vacation" AND "family" +let merged = resolver.merge_tag_applications(local_apps, remote_apps).await?; +``` + +This prevents data loss and preserves all user intent during synchronization. + +## Manager Layer + +### TagManager + +Core manager providing high-level tag operations.
