11 - Document Management: Versioning, Categories and Sharing

Play The Event document system: Aggregate Root with full versioning, 11 predefined categories, temporary sharing links, metadata extraction and SHA-256 integrity.

What you'll learn

• Documents are modeled as Aggregate Roots with optimistic locking for concurrent access safety
• 11 predefined categories cover common event document types, with custom categories for flexibility
• Automatic folder detection routes files to DOCUMENTI, IMMAGINI, or RICEVUTE based on MIME type and category
• Full versioning preserves complete history; restoring a version creates a new entry, never overwrites
• Sharing links provide controlled external access with expiration, download limits, and revocation
