Overview

The Event System represents a comprehensive refactoring and enhancement of the existing event management platform, moving beyond a simple approval-centric model to a sophisticated, multi-tier stakeholder system with global configuration capabilities.

Key Objectives

  • Expand beyond approvals: Support notification and acknowledgment workflows
  • Global configuration: Top-level system configuration from root dashboard
  • Domain-specific management: Dedicated dashboards for different authorities
  • Stakeholder roles: Institutional positions that can be assigned to users
  • Closed-source architecture: Events module isolated for proprietary licensing
