Sources Design

This section documents the design of data acquisition modules. Each source has its own scraping strategy, rate limiting considerations, and data validation rules.

🌐 Available Sources

Source	Region	Data Type	Status
ANVISA	Brazil	Drug leaflets, registrations	Active

🔧 Common Patterns

All source modules follow these design principles:

1. Idempotent scraping - Re-running produces same results
2. Incremental updates - Only fetch new/changed data
3. Checkpoint persistence - Resume from failure points
4. Rate limiting - Respect source server constraints
