# SDK Education Library API

**Digital Learning Hub with Relationship-Centered Literacy**

🎯 **Mission**: Create relationship-intelligent library platform following proven AdminAPI delegation pattern with 67% dependency reduction and zero code duplication.

## 🏗️ Architecture: Perfect Delegation Pattern

### **First Principles Design**

- **OWNS**: Library orchestration, resource management, circulation, literacy programs
- **DELEGATES**: All core education data to `sdk-education-core` services
- **INTEGRATES**: Relationship intelligence for learning facilitation
- **ZERO DUPLICATION**: 2 SDK dependencies vs typical 6+ (67% reduction)

### **Service Delegation**

```typescript
// All education data delegated to core services:
this.services = {
  student: StudentService, // → sdk-education-core
  course: CourseService, // → sdk-education-core
  grade: GradeService, // → sdk-education-core
  attendance: AttendanceService, // → sdk-education-core
  relationship: RelationshipService, // → sdk-education-core (476 lines competitive intelligence)
};

// Library API OWNS only orchestration and library-specific features
```

## 🚀 Quick Start

### Installation

```bash
yarn add @iota-big3/sdk-education-library-api
```

### Basic Usage

```typescript
import { LibraryAPI } from "@iota-big3/sdk-education-library-api";

const libraryAPI = new LibraryAPI({
  settings: {
    port: 3007,
    relationshipIntelligence: true,
    chattanoogaMode: false, // Enable for Chattanooga Prep DNA features
  },
});

await libraryAPI.start();
console.log("Library API running on port 3007");
```

## 📚 Core Features

### **1. Resource Management** (What This API OWNS)

#### Add Library Resources

```typescript
const resource = await libraryAPI.addResource({
  title: "To Kill a Mockingbird",
  type: "book",
  isbn: "978-0-06-112008-4",
  subject: ["literature", "social-justice"],
  readingLevel: 8,
  availability: "available",
  relationshipContext: {
    preferredByStudents: ["student_123", "student_456"],
    teacherRecommendations: [
      {
        teacherId: "teacher_789",
        reason: "Excellent for discussing empathy and moral courage",
      },
    ],
    learningStyleMatch: "reading",
  },
});
```

#### Get Relationship-Based Recommendations

```typescript
// Uses RelationshipService to analyze student bonds and preferences
const recommendations =
  await libraryAPI.getResourceRecommendations("student_123");
// Returns resources recommended by students with strong relationships
```

### **2. Circulation Management** (Relationship-Intelligent)

#### Check Out Resources

```typescript
const checkout = await libraryAPI.checkoutResource({
  resourceId: "resource_123",
  studentId: "student_456",
  librarianId: "librarian_789",
  dueDate: new Date(Date.now() + 14 * 24 * 60 * 60 * 1000), // 2 weeks
});
// Automatically tracks student-librarian relationship bond strength
```

#### Track Student Checkouts

```typescript
const studentCheckouts = await fetch(
  "/library/checkout/student/student_123"
).then((res) => res.json());
// Returns active checkouts with relationship context
```

### **3. Literacy Programs** (Relationship Building)

#### Create Reading Programs

```typescript
const program = await libraryAPI.createLiteracyProgram({
  name: "Advanced Research Skills",
  type: "research_skills",
  targetGrades: [9, 10, 11, 12],
  description: "Develop critical thinking and source evaluation skills",
  schedule: {
    dayOfWeek: "Tuesday",
    startTime: "15:30",
    duration: 60,
  },
  relationshipBuilding: {
    mentorPairings: [{ studentId: "student_123", mentorId: "librarian_456" }],
    peerConnections: [
      {
        student1Id: "student_123",
        student2Id: "student_789",
        connectionType: "research_partners",
      },
    ],
    librarian: {
      id: "librarian_456",
      specialties: ["research", "digital-literacy"],
      bondStrengths: [{ studentId: "student_123", strength: "strong" }],
    },
  },
});
```

### **4. Research Support** (Learning Relationship Facilitation)

#### Start Research Projects

```typescript
const project = await libraryAPI.startResearchProject({
  studentId: "student_123",
  title: "Impact of Social Media on Teen Mental Health",
  subject: "psychology",
  assignedTeacherId: "teacher_456",
  librarianMentorId: "librarian_789",
  resources: [],
  relationshipGuidance: {
    librarianConsultations: [],
    peerCollaborations: [],
    teacherCheckIns: [],
  },
});
```

### **5. Relationship Intelligence Analytics**

#### Get Literacy Growth Metrics

```typescript
const metrics = await libraryAPI.getLiteracyGrowthMetrics("student_123");
console.log({
  currentLevel: metrics.currentLevel,
  growthRate: metrics.growthRate,
  librarianMentorshipImpact:
    metrics.relationshipFactors.librarianMentorshipImpact,
});
```
