**Module**: Publishing Tools
**Author**: Publishing Team Lead
**Date**: 2025-01-19
**Status**: Example/Template

## 1. Module Overview

The Publishing Tools module enables creators to distribute knowledge graph insights through multiple channels including email newsletters, API webhooks, and personalized content feeds. It transforms processed knowledge into audience-appropriate formats while tracking engagement and optimizing delivery timing.

## 2. User Stories

### Primary User Story
As a content creator, I want to automatically distribute my knowledge insights to my audience through their preferred channels so that I can maintain engagement without manual effort.

### Secondary Stories
1. As a creator, I want to schedule content distribution at optimal times so that I maximize audience engagement
2. As a subscriber, I want to receive personalized content based on my interests so that I only get relevant information
3. As a creator, I want to track engagement metrics so that I can understand what resonates with my audience
4. As an API consumer, I want to receive structured data via webhooks so that I can integrate insights into my applications

## 3. Functional Requirements

### Core Features (MUST have)
- FR-001: System MUST support email newsletter distribution to subscriber lists
- FR-002: System MUST provide webhook delivery for API integrations
- FR-003: System MUST format content based on delivery channel requirements
- FR-004: Users MUST be able to schedule content distribution
- FR-005: System MUST track basic engagement metrics (opens, clicks)
- FR-006: System MUST support subscriber management (add, remove, preferences)
- FR-007: System MUST generate content from knowledge graph data
- FR-008: System MUST handle distribution failures with retry logic

### Nice-to-Have Features (SHOULD have)
- FR-101: System SHOULD support RSS feed generation
- FR-102: System SHOULD provide A/B testing for content variations
- FR-103: System SHOULD optimize send times based on engagement data
- FR-104: System SHOULD support custom branding for emails

## 4. Data Requirements

### Key Entities
- **Subscriber**: Represents an audience member with email, preferences, engagement history
- **Distribution**: Represents a content distribution event with channel, schedule, status
- **Template**: Represents a content format template with placeholders and styling
- **Engagement**: Represents interaction data including opens, clicks, unsubscribes
- **Channel**: Represents a distribution method (email, webhook, RSS)

### Data Constraints
- Data retention: Engagement data kept for 12 months
- Subscriber data: Must comply with GDPR/CCPA requirements
- Template size: Maximum 1MB per template
- Distribution queue: Maximum 10,000 pending items

## 5. Integration Points

### Inputs (What this module receives)
- From AI Module: Processed knowledge graph insights and summaries
- From Backend: User authentication and authorization tokens
- From Frontend: Distribution scheduling and configuration settings

### Outputs (What this module provides)
- To External: Formatted emails to subscriber addresses
- To External: JSON payloads to webhook endpoints
- To Backend: Engagement metrics and distribution status
- To Frontend: Real-time distribution progress updates

## 6. Acceptance Criteria

### Scenario 1: Email Newsletter Distribution
**Given** a creator has 1000 subscribers and new knowledge insights
**When** they schedule a newsletter for 9 AM tomorrow
**Then** all active subscribers receive the formatted email at the scheduled time

### Scenario 2: Webhook Delivery
**Given** an API consumer has registered a webhook endpoint
**When** new insights matching their criteria are available
**Then** the system sends a properly formatted JSON payload to their endpoint

### Scenario 3: Failed Delivery Handling
**Given** an email delivery fails due to a temporary error
**When** the system detects the failure
**Then** it retries delivery up to 3 times with exponential backoff

### Scenario 4: Subscriber Preferences
**Given** a subscriber has set preferences for weekly digests only
**When** daily content is available
**Then** the system aggregates content and sends only on their preferred schedule

## 7. Non-Functional Requirements

### Performance
- Email sending: Process 1000 emails per minute
- Webhook delivery: < 500ms response time
- Template rendering: < 100ms per template

### Security
- Authentication: API key required for all operations
- Data encryption: TLS for all external communications
- Email validation: Verify addresses before sending

### Scalability
- Support up to 100,000 subscribers per creator
- Handle 1 million daily distributions across all users
- Queue system to handle traffic spikes

### Reliability
- 99.9% uptime for distribution services
- Delivery success rate > 95% for valid addresses
- Automatic failover for critical components

## 8. Constraints & Assumptions

### Constraints
- Budget: Use existing email service providers (no custom SMTP)
- Timeline: MVP must be ready for Phase 3 (4 weeks)
- Technology: Must integrate with FastAPI backend
- Compliance: Must follow CAN-SPAM and GDPR requirements

### Assumptions
- Email service provider (SendGrid/SES) will be available
- Knowledge graph data will be in standardized JSON format
- Subscribers will self-manage their preferences
- Webhook endpoints will handle their own authentication

## 9. Success Metrics
- Delivery Rate: > 95% successful deliveries
- Engagement Rate: > 25% open rate for emails
- Processing Speed: < 5 minutes from trigger to delivery
- User Satisfaction: > 4.0/5.0 rating from creators

## 10. Open Questions
- [NEEDS CLARIFICATION: Preferred email service provider - SendGrid, AWS SES, or other?]
- [NEEDS CLARIFICATION: Maximum number of retry attempts for failed deliveries?]
- [NEEDS CLARIFICATION: Should we support SMS/push notifications in future phases?]
- [NEEDS CLARIFICATION: Required email template customization level - basic or full HTML control?]
