CLAUDE.md - ZiRA Classificatie Tool

Project Overview

Project: ZiRA Classificatie Tool (Zuyderland CMDB Editor) Organization: Zuyderland Medisch Centrum - ICMT Purpose: Interactive tool for classifying ~500 application components into ZiRA (Ziekenhuis Referentie Architectuur) application functions with Jira Assets CMDB integration.

Current Status

Phase: v1.0 - First Implementation Complete

The project has a working implementation with:

• Full backend API with Express + TypeScript
• React frontend with Dashboard, Application List, and Detail views
• Mock data service for development (can be switched to Jira Assets)
• AI classification integration with Claude API
• SQLite database for classification history

Key files:

• zira-classificatie-tool-specificatie.md - Complete technical specification
• zira-taxonomy.json - ZiRA taxonomy with 90+ application functions across 10 domains
• management-parameters.json - Reference data for dynamics, complexity, users, governance models

Technology Stack

Frontend

• React + TypeScript
• Vite (build tool)
• TailwindCSS

Backend

• Node.js + Express + TypeScript
• SQLite (local caching)

External Integrations

• Jira Data Center REST API (Assets CMDB) - source of truth for application data
• Anthropic Claude API (claude-sonnet-4-20250514) - AI classification suggestions

cd backend && npm install && npm run dev

# Frontend development
cd frontend && npm install && npm run dev

# Docker (full stack)

Key Domain Concepts

ZiRA (Ziekenhuis Referentie Architectuur)

Dutch hospital reference architecture with 90+ application functions organized in 10 domains:

• Sturing (Governance)
• Onderzoek (Research)
• Zorg-SAM, Zorg-CON, Zorg-AOZ, Zorg-ZON (Care delivery)
• Onderwijs (Education)
• Bedrijfsondersteuning (Business support)
• Generieke ICT (IT infrastructure)

Editable Classification Fields

• ApplicationFunction - ZiRA taxonomy match
• Dynamics Factor - 1-4 scale (Stabiel to Zeer hoog)
• Complexity Factor - 1-4 scale (Laag to Zeer hoog)
• Number of Users - 7 ranges (< 100 to > 15.000)
• Governance Model - A-E (Centraal to Volledig Decentraal)

AI Classification Confidence

• HOOG (high) - Strong match, can auto-apply
• MIDDEN (medium) - Reasonable match, needs review
• LAAG (low) - Uncertain, requires manual classification

Implementation Notes

1. Never commit PAT tokens - Always use .env files (add to .gitignore)
2. Jira Assets is source of truth - SQLite is for local caching only
3. Rate limiting - Implement exponential backoff for Jira API calls
4. Validation - Verify ApplicationFunction objects exist before updating
5. Audit trail - Comprehensive logging for all classifications
6. Reference data sync - Fetch from Jira Assets on startup
7. Navigation state - Maintain filter state when navigating between screens

Development Roadmap

1. Phase 1 - Setup: Project initialization, Vite + Express, Jira API connection test
2. Phase 2 - Backend: Services, API endpoints, error handling
3. Phase 3 - Frontend: Dashboard, classification workflow, state management
4. Phase 4 - Integration: E2E testing, bulk operations, reporting/export
5. Phase 5 - Deployment: Tests, documentation, deployment setup
