Format: Base64 compressed JSON structure Purpose: Shareable composition URLs and state transport ``` 3. **File UID Layer**: ```javascript // Persistent database reference Parameter: ?file_uid=e0105340-d412-4e50-b768-92e43a4c1962 Format: UUID-style unique identifier Purpose: Long-term persistence and composition management ``` --- ## 🧩 **JSON STRUCTURE ANALYSIS** ### **Composition Schema (v1.0.4 Validated)** ```javascript { composition: { // Core metadata id: "composition-{timestamp}", // Unique composition identifier title: "Generated Title", // User prompt-derived title description: "Generated Description", // Subject and context description author: "Sistema Inteligente EuConquisto", // System identification created: "YYYY-MM-DD", // Creation date stamp version: "1.0.0", // Composition format version // Optional metadata metadata: { disciplina: "Subject Name", // Educational subject serie: "Grade Level", // Target grade/year duracao_estimada: "45 minutos", // Estimated duration tags: ["tag1", "tag2", "tag3"] // Searchable tags }, // Content elements array elements: [ { // Element identification id: "element-{counter}", // Unique element ID type: "element-type", // Element type (head-1, text-1, etc.) content_title: "Element Title", // Display title // Layout properties padding_top: 0, // Top spacing padding_bottom: 30, // Bottom spacing // Content properties (type-specific) content: "Text content...", // Main content (text elements) background_color: "#4CAF50", // Background color primary_color: "#4CAF50", // Primary theme color // Type-specific properties // ... (varies by element type) } ] } } ``` ### **Element Types Analysis** (From /docs/references/json-example.md) **Header Elements (head-1):** - Background images and colors - Author information and avatars - Category and progress tracking - Font family and styling options **Text Elements (text-1):** - Rich text content with formatting - Text alignment and typography - Font size and line height control - Multiple text layout variants **Interactive Elements:** - Quiz elements (quiz-1) with questions and answers - Hotspot elements (hotspot-1) with interactive points - Multimedia integration capabilities - Activity and assessment components --- ## 🔧 **IMPLEMENTATION REQUIREMENTS** ### **Core Component Requirements** **1.
