## 2. Flux de données principal

### Pipeline Orion-LD (Fonctionnel ✅)
```
Simulator → MQTT Brokers (Mosquitto/EMQX/BunkerM) → IoT Agents → Orion-LD → QuantumLeap → CrateDB (standard) → Grafana
```

### Pipeline Stellio (En cours de debug ⚠️)
```
Simulator → MQTT Brokers → IoT Agents → Stellio Context Broker → QuantumLeap-Stellio → CrateDB-Stellio → Grafana
```

## 6. État des Pipelines

### ✅ Pipeline Orion-LD (Opérationnel)
- **Statut** : Entièrement fonctionnel
- **Données** : CrateDB contient 6 tables avec données (`etairqualityobserved` a 6+ rows)
- **Grafana** : Dashboard "Smart City - Air Quality (CrateDB)" fonctionnel
- **Subscription** : Orion-LD → QuantumLeap active (`lastNotification: 2026-05-07`)

### ⚠️ Pipeline Stellio (Debug en cours)
- **Statut** : Subscription créée, notifications reçues par QuantumLeap-Stellio
- **Problème** : Données ne persistent pas dans CrateDB-Stellio (0 rows)
- **Cause probable** : Mappage NGSI-LD → CrateDB incompatible
- **Subscription Stellio** : `urn:ngsi-ld:Subscription:0baad89d-1625-4b42-adc1-e841e04120ff`
  - Endpoint : `http://smart-city-quantumleap-stellio:8668/v2/notify`
  - Format : NGSI-LD normalized

## 8. Connexions Clés

1. **Traefik** (`:80`/`:443`) : Reverse proxy pour tous les services exposés à l'hôte.
2. **Brokers MQTT** (Mosquitto `:1883`, EMQX `:11883`) : Réception des données du simulateur et des capteurs IoT.
3. **Context Brokers** (Orion-LD `:1026`, Stellio `:8080`) : Gestion des entités NGSI-LD.
4. **Time-Series DB** (CrateDB `:4200` HTTP API, `:5432` PostgreSQL) : Persistance des données pour Grafana.
5. **Grafana** (`:3000`) : Visualisation des données depuis CrateDB, InfluxDB, Prometheus.
