+## Overview
+
+This specification defines the requirements and implementation details for importing and exporting EPUB files in StoryCove. The feature enables users to import stories from EPUB files and export their stories/collections as EPUB files with preserved reading positions.
+
+## Scope
+
+### In Scope
+- **EPUB Import**: Parse DRM-free EPUB files and import as stories
+- **EPUB Export**: Export individual stories and collections as EPUB files
+- **Reading Position Preservation**: Store and restore reading positions using EPUB standards
+- **Metadata Handling**: Extract and preserve story metadata (title, author, cover, etc.)
+- **Content Processing**: HTML content sanitization and formatting
+
+### Out of Scope (Phase 1)
+- DRM-protected EPUB files (future consideration)
+- Real-time reading position sync between devices
+- Advanced EPUB features (audio, video, interactive content)
+- EPUB validation beyond basic structure
+
+## Technical Architecture
+
+### Backend Implementation
+- **Language**: Java (Spring Boot)
+- **Primary Library**: EPUBLib (nl.siegmann.epublib:epublib-core:3.1)
+- **Processing**: Server-side generation and parsing
+- **File Handling**: Multipart file upload for import, streaming download for export
+
+### Dependencies
+```xml
+<dependency>
+    <groupId>com.positiondev.epublib</groupId>
+    <artifactId>epublib-core</artifactId>
+    <version>3.1</version>
+</dependency>
+```
+
+### Phase 1 Implementation Notes
+- **EPUBImportService**: Implemented with full validation, metadata extraction, and reading position handling
+- **EPUBExportService**: Implemented with XML validation fixes for EPUB reader compatibility  
+- **ReadingPosition Entity**: Created with EPUB CFI support and database indexing
+- **Authentication**: All endpoints secured with JWT authentication and proper frontend integration
+- **UI Integration**: Export moved to Story Detail View, Import added to main navigation menu
+- **XML Compliance**: Fixed XHTML validation issues by properly formatting self-closing tags (`<br>` → `<br />`)
+
+## EPUB Import Specification
+
+### Supported Formats
+- **EPUB 2.0** and **EPUB 3.x** formats
+- **DRM-Free** files only
+- **Maximum file size**: 50MB
+- **Supported content**: Text-based stories with HTML content
+
+### Import Process Flow
+1. **File Upload**: User uploads EPUB file via web interface
+2. **Validation**: Check file format, size, and basic EPUB structure
+3. **Parsing**: Extract metadata, content, and resources using EPUBLib
+4. **Content Processing**: Sanitize HTML content using existing Jsoup pipeline
+5. **Story Creation**: Create Story entity with extracted data
+6. **Preview**: Show extracted story details for user confirmation
+7. **Finalization**: Save story to database with imported metadata
+
+### Metadata Mapping
+```java
+// EPUB Metadata → StoryCove Story Entity
+epub.getMetadata().getFirstTitle() → story.title
+epub.getMetadata().getAuthors().get(0) → story.authorName  
+epub.getMetadata().getDescriptions().get(0) → story.summary
+epub.getCoverImage() → story.coverPath
+epub.getMetadata().getSubjects() → story.tags
+```
+
+### Content Extraction
+- **Multi-chapter EPUBs**: Combine all content files into single HTML
+- **Chapter separation**: Insert `<hr>` or `<h2>` tags between chapters
+- **HTML sanitization**: Apply existing sanitization rules
+- **Image handling**: Extract and store cover images, inline images optional
+
+### API Endpoints
+
+#### POST /api/stories/import-epub
+```java
+@PostMapping("/import-epub")
+public ResponseEntity<?> importEPUB(@RequestParam("file") MultipartFile file) {
+    // Implementation in EPUBImportService
+}
+```
+
+**Request**: Multipart file upload
+**Response**: 
+```json
+{
+  "message": "EPUB imported successfully",
+  "storyId": "uuid",
+  "extractedData": {
+    "title": "Story Title",
+    "author": "Author Name",
+    "summary": "Story description",
+    "chapterCount": 12,
+    "wordCount": 45000,
+    "hasCovers": true
+  }
+}
+```
+
+## EPUB Export Specification
+
+### Export Types
+1. **Single Story Export**: Convert one story to EPUB
+2. **Collection Export**: Multiple stories as single EPUB with chapters
+
+### EPUB Structure Generation
+```
+story.epub
+├── mimetype
+├── META-INF/
+│   └── container.xml
+└── OEBPS/
+    ├── content.opf          # Package metadata
+    ├── toc.ncx              # Navigation
+    ├── stylesheet.css       # Styling
+    ├── cover.html           # Cover page
+    ├── chapter001.xhtml     # Story content
+    ├── images/
+    │   └── cover.jpg        # Cover image
+    └── fonts/ (optional)
+```
+
+### Reading Position Implementation
+
+#### EPUB 3 CFI (Canonical Fragment Identifier)
+```xml
+<!-- In content.opf metadata -->
+<meta property="epub-cfi" content="/6/4[chap01]!/4[body01]/10[para05]/3:142"/>
+<meta property="reading-percentage" content="0.65"/>
+<meta property="last-read-timestamp" content="2023-12-07T10:30:00Z"/>
+```
+
+#### StoryCove Custom Metadata (Fallback)
+```xml
+<meta name="storycove:reading-chapter" content="3"/>
+<meta name="storycove:reading-paragraph" content="15"/>
+<meta name="storycove:reading-offset" content="142"/>
+<meta name="storycove:reading-percentage" content="0.65"/>
+```
+
+#### CFI Generation Logic
+```java
+public String generateCFI(ReadingPosition position) {
+    return String.format("/6/%d[chap%02d]!/4[body01]/%d[para%02d]/3:%d",
+        (position.getChapterIndex() * 2) + 4, 
+        position.getChapterIndex(),
+        (position.getParagraphIndex() * 2) + 4,
+        position.getParagraphIndex(),
+        position.getCharacterOffset());
+}
+```
+
+### API Endpoints
+
+#### GET /api/stories/{id}/export-epub
+```java
+@GetMapping("/{id}/export-epub")
+public ResponseEntity<StreamingResponseBody> exportStory(@PathVariable UUID id) {
+    // Implementation in EPUBExportService
+}
+```
+
+**Response**: EPUB file download with headers:
+```
+Content-Type: application/epub+zip
+Content-Disposition: attachment; filename="story-title.epub"
+```
+
+#### GET /api/collections/{id}/export-epub  
+```java
+@GetMapping("/{id}/export-epub")
+public ResponseEntity<StreamingResponseBody> exportCollection(@PathVariable UUID id) {
+    // Implementation in EPUBExportService
+}
+```
+
+**Response**: Multi-story EPUB with table of contents

+3. **Progress Indicator**: Show EPUB generation progress  
+4. **Download**: Automatic file download on completion
+
+### Frontend API Calls
+```typescript
+// Import EPUB
+const importEPUB = async (file: File) => {
+  const formData = new FormData();
+  formData.append('file', file);
+  
+  const response = await fetch('/api/stories/import-epub', {
+    method: 'POST',
+    body: formData,
+  });
+  
+  return await response.json();
+};
+
+// Export Story
+const exportStoryEPUB = async (storyId: string) => {
+  const response = await fetch(`/api/stories/${storyId}/export-epub`, {
+    method: 'GET',
+  });
+  
+  const blob = await response.blob();
+  const url = window.URL.createObjectURL(blob);
+  const a = document.createElement('a');
+  a.href = url;
+  a.download = `${storyTitle}.epub`;
+  a.click();
+};
+```
+
+## Error Handling
+
+### Import Errors
+- **Invalid EPUB format**: "Invalid EPUB file format"
+- **File too large**: "File size exceeds 50MB limit"
+- **DRM protected**: "DRM-protected EPUBs not supported"
+- **Corrupted file**: "EPUB file appears to be corrupted"
+- **No content**: "EPUB contains no readable content"
+
+### Export Errors  
+- **Story not found**: "Story not found or access denied"
+- **Missing content**: "Story has no content to export"
+- **Generation failure**: "Failed to generate EPUB file"
+
+## Security Considerations
+
+### File Upload Security
+- **File type validation**: Verify EPUB MIME type and structure
+- **Size limits**: Enforce maximum file size limits
+- **Content sanitization**: Apply existing HTML sanitization
+- **Virus scanning**: Consider integration with antivirus scanning
+

+# Tag Enhancement Specification
+
+> **✅ Implementation Status: COMPLETED**
+> This feature has been fully implemented and is available in the system.
+> All tag enhancements including colors, aliases, merging, and AI suggestions are working.
+> Last updated: January 2025
+
+## Overview
+
+This document outlines the comprehensive enhancement of the tagging functionality in StoryCove, including color tags, tag deletion, merging, and aliases. These features will be accessible through a new "Tag Maintenance" page linked from the Settings page.
+
+## Features
+
+### 1. Color Tags
+
+**Purpose**: Assign optional colors to tags for visual distinction and better organization.
+
+**Implementation Details**:
+- **Color Selection**: Predefined color palette that complements the app's theme
+- **Custom Colors**: Fallback option with full color picker for advanced users
+- **Default Behavior**: Tags without colors use consistent default styling
+- **Accessibility**: All colors ensure sufficient contrast ratios
+
+**UI Design**:
+```
+Color Selection Interface:
+[Theme Blue] [Theme Green] [Theme Purple] [Theme Orange] ... [Custom ▼]
+```
+
+**Database Changes**:
+```sql
+ALTER TABLE tags ADD COLUMN color VARCHAR(7); -- hex colors like #3B82F6
+ALTER TABLE tags ADD COLUMN description TEXT;
+```
+
+### 2. Tag Deletion
+
+**Purpose**: Remove unused or unwanted tags from the system.
+
+**Safety Features**:
+- Show impact: "This tag is used by X stories"
+- Confirmation dialog with story count
+- Option to reassign stories to different tag before deletion
+- Simple workflow appropriate for single-user application
+
+**Behavior**:
+- Display number of affected stories
+- Require confirmation for deletion
+- Optionally allow reassignment to another tag
+
+### 3. Tag Merging
+
+**Purpose**: Combine similar tags into a single canonical tag to reduce duplication.
+
+**Workflow**:
+1. User selects multiple tags to merge
+2. User chooses which tag name becomes canonical
+3. System shows merge preview with story counts
+4. All story associations transfer to canonical tag
+5. **Automatic Aliasing**: Merged tags automatically become aliases
+
+**Example**:
+```
+Merge Preview:
+• "magictf" (5 stories) → "magic tf" (12 stories)
+• Result: "magic tf" (17 stories)
+• "magictf" will become an alias for "magic tf"
+```
+
+**Technical Implementation**:
+```sql
+-- Merge operation (atomic transaction)
+BEGIN TRANSACTION;
+UPDATE story_tags SET tag_id = target_tag_id WHERE tag_id = source_tag_id;
+INSERT INTO tag_aliases (alias_name, canonical_tag_id, created_from_merge) 
+VALUES (source_tag_name, target_tag_id, TRUE);
+DELETE FROM tags WHERE id = source_tag_id;
+COMMIT;
+```
+
+### 4. Tag Aliases
+
+**Purpose**: Prevent tag duplication by allowing alternative names that resolve to canonical tags.
+
+**Key Features**:
+- **Transparent Resolution**: Users type "magictf" and automatically get "magic tf"
+- **Hover Display**: Show aliases when hovering over tags
+- **Import Integration**: Automatic alias resolution during story imports
+- **Auto-Generation**: Created automatically during tag merges
+
+**Database Schema**:
+```sql
+CREATE TABLE tag_aliases (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    alias_name VARCHAR(255) UNIQUE NOT NULL,
+    canonical_tag_id UUID NOT NULL REFERENCES tags(id) ON DELETE CASCADE,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    created_from_merge BOOLEAN DEFAULT FALSE
+);
+
+CREATE INDEX idx_tag_aliases_name ON tag_aliases(alias_name);
+```
+
+**UI Behavior**:
+- Tags with aliases show subtle indicator (e.g., small "+" icon)
+- Hover tooltip displays:
+  ```
+  magic tf
+  ────────────
+  Aliases: magictf, magic_tf, magic-transformation
+  ```
+
+## Tag Maintenance Page
+
+### Access
+- Reachable only through Settings page
+- Button: "Tag Maintenance" or "Manage Tags"
+
+### Main Interface
+
+**Tag Management Table**:
+```
+┌─ Search: [____________] [Color Filter ▼] [Sort: Usage ▼]
+├─ 
+├─ ☐ magic tf        🔵 (17 stories) [+2 aliases] [Edit] [Delete]
+├─ ☐ transformation  🟢 (34 stories) [+1 alias]  [Edit] [Delete]
+├─ ☐ sci-fi          🟣 (45 stories)              [Edit] [Delete]
+└─ 
+   [Merge Selected] [Bulk Delete] [Export/Import Tags]
+```
+
+**Features**:
+- Searchable and filterable tag list
+- Sortable by name, usage count, creation date
+- Bulk selection for merge/delete operations
+- Visual indicators for color and alias count
+
+### Tag Edit Modal
+
+```
+Edit Tag: "magic tf"
+┌─ Name: [magic tf                    ]
+├─ Color: [🔵] [Theme Colors...] [Custom...]
+├─ Description: [Optional description]
+├─ 
+├─ Aliases (2):
+│  • magictf [Remove]
+│  • magic_tf [Remove]
+│  [Add Alias: ____________] [Add]
+├─
+├─ Used by 17 stories [View Stories]
+└─ [Save] [Cancel]
+```
+
+**Functionality**:
+- Edit tag name, color, and description
+- Manage aliases (add/remove)
+- View associated stories
+- Prevent circular alias references
+
+### Merge Interface
+
+**Selection Process**:
+1. Select multiple tags from main table
+2. Click "Merge Selected"
+3. Choose canonical tag name
+4. Preview merge results
+5. Confirm operation
+
+**Preview Display**:
+- Show before/after story counts
+- List all aliases that will be created
+- Highlight any conflicts or issues
+
+## Integration Points
+
+### 1. Import/Scraping Enhancement
+
+```javascript
+// Tag resolution during imports
+const resolveTagName = async (inputTag) => {
+  const alias = await tagApi.findAlias(inputTag);
+  return alias ? alias.canonicalTag : inputTag;
+};
+```
+
+### 2. Tag Input Components
+
+**Enhanced Autocomplete**:
+- Include both canonical names and aliases in suggestions
+- Show resolution: "magictf → magic tf" in dropdown
+- Always save canonical name to database
+
+### 3. Search Functionality
+
+**Transparent Alias Search**:
+- Search for "magictf" includes stories tagged with "magic tf"
+- User doesn't need to know about canonical/alias distinction
+- Expand search queries to include all aliases
+
+### 4. Display Components
+
+**Tag Rendering**:
+- Apply colors consistently across all tag displays
+- Show alias indicator where appropriate
+- Implement hover tooltips for alias information
+
+## Implementation Phases

+- Keyboard navigation support
+- Screen reader compatibility
+- Don't rely solely on color for information
+
+## API Endpoints
+
+### New Endpoints Needed
+- `GET /api/tags/{id}/aliases` - Get aliases for a tag
+- `POST /api/tags/merge` - Merge multiple tags
+- `POST /api/tags/{id}/aliases` - Add alias to tag
+- `DELETE /api/tags/{id}/aliases/{aliasId}` - Remove alias
+- `PUT /api/tags/{id}/color` - Update tag color

+
+### Enhanced Endpoints
+- `GET /api/tags` - Include color and alias count in response
+- `PUT /api/tags/{id}` - Support color and description updates
+- `DELETE /api/tags/{id}` - Enhanced with story impact information
+
+## Configuration
+
+### Theme Color Palette
+Define a curated set of colors that work well with both light and dark themes:
+- Primary blues: #3B82F6, #1D4ED8, #60A5FA
+- Greens: #10B981, #059669, #34D399
+- Purples: #8B5CF6, #7C3AED, #A78BFA
+- Warm tones: #F59E0B, #D97706, #F97316
+- Neutrals: #6B7280, #4B5563, #9CA3AF
+
+### Settings Integration
+- Add "Tag Maintenance" button to Settings page
+- Consider adding tag-related preferences (default colors, etc.)
+
+## Success Criteria
+
+1. **Color Tags**: Tags can be assigned colors that display consistently throughout the application
+2. **Tag Deletion**: Users can safely delete tags with appropriate warnings and reassignment options
+3. **Tag Merging**: Similar tags can be merged with automatic alias creation
+4. **Alias Resolution**: Imports automatically resolve aliases to canonical tags
+5. **User Experience**: All operations are intuitive with clear feedback and preview options
+6. **Performance**: Tag operations remain fast even with large numbers of tags and aliases
+7. **Data Integrity**: No orphaned references or circular alias chains
+
+## Future Enhancements
+
+- **Tag Statistics**: Usage analytics and trends
+- **Tag Recommendations**: AI-powered tag suggestions during story import
+- **Tag Templates**: Predefined tag sets for common story types
+- **Export/Import**: Backup and restore tag configurations
+- **Tag Validation**: Rules for tag naming conventions

+- Foreign key to `stories(id)` with CASCADE DELETE
+- Foreign key to `tags(id)` with CASCADE DELETE
+
+**Indexes:**
+- Composite primary key index
+- Index on `tag_id` for reverse lookups
+
+## Data Types and Conventions
+
+### UUID Strategy
+- All primary keys use UUID (Universally Unique Identifier)
+- Generated using `GenerationType.UUID` in Hibernate
+- Provides natural uniqueness across distributed systems
+- 36-character string representation (e.g., `123e4567-e89b-12d3-a456-426614174000`)
+
+### Timestamp Management
+- All entities have `created_at` timestamp
+- Stories and Authors have `updated_at` timestamp (automatically updated)
+- Series and Tags only have `created_at` (they're rarely modified)
+- All timestamps use `LocalDateTime` in Java, stored as `TIMESTAMP` in PostgreSQL
+
+### Text Fields
+- **VARCHAR(n)**: For constrained text fields (names, paths, URLs)
+- **TEXT**: For unlimited text content (story content, notes, descriptions)
+- **HTML Content**: Stored as-is but sanitized on input and output
+- **Plain Text**: Automatically extracted from HTML using Jsoup
+
+### Validation Rules
+- **Required Fields**: Entity names/titles are always required
+- **Length Limits**: Names limited to 255 characters, descriptions to 1000
+- **Rating Range**: All ratings constrained to 1-5 range
+- **URL Format**: No format validation at database level
+- **Uniqueness**: Names are unique within their entity type
+
+## Relationships and Cascading
+
+### One-to-Many Relationships
+- **Author → Stories**: Lazy loaded, cascade ALL operations
+- **Series → Stories**: Lazy loaded, ordered by volume, cascade ALL
+- **Author → Author URLs**: Eager loaded via `@ElementCollection`
+
+### Many-to-Many Relationships
+- **Stories ↔ Tags**: Via `story_tags` junction table
+- Managed bidirectionally with helper methods
+- Cascade DELETE on both sides
+
+### Foreign Key Constraints
+- All foreign keys have proper referential integrity
+- DELETE operations cascade appropriately
+- No orphaned records are allowed
+
+## Performance Considerations
+
+### Indexing Strategy
+- Primary keys automatically indexed
+- Foreign keys have dedicated indexes
+- Frequently queried fields (rating, created_at) are indexed
+- Unique constraints automatically create indexes
+
+### Query Optimization
+- Lazy loading prevents N+1 queries
+- Pagination used for large result sets
+- Specialized queries for common access patterns
+- Typesense search engine for full-text search (separate from PostgreSQL)
+
+### Data Volume Estimates
+- **Stories**: Expected 1K-10K records per user
+- **Authors**: Expected 100-1K records per user
+- **Tags**: Expected 50-500 records per user
+- **Series**: Expected 10-100 records per user
+- **Join Tables**: Scale with story count and tagging usage
+
+## Backup and Migration Considerations
+
+### Schema Evolution
+- Uses Hibernate `ddl-auto: update` for development
+- Production should use controlled migration tools (Flyway/Liquibase)
+- UUID keys allow safe data migration between environments
+
+### Data Integrity
+- Foreign key constraints ensure referential integrity
+- Check constraints validate data ranges
+- Application-level validation provides user-friendly error messages
+- Unique constraints prevent duplicate data
+
+### Backup Strategy
+- Full PostgreSQL dumps for complete backup
+- Image files stored separately in filesystem
+- Consider incremental backups for large installations
+- Test restore procedures regularly
+
+This data model provides a solid foundation for personal story library management with room for future enhancements while maintaining data integrity and performance.
