# Data Quality Monitoring Dashboard

## 📋 Overview

The Data Quality Monitoring Dashboard provides real-time monitoring and historical tracking of data quality metrics for the Citizen Intelligence Agency's four primary OSINT (Open-Source Intelligence) data sources.

**Version**: 1.0.0  
**Status**: Initial Implementation (Phase 1 Complete)  
**Last Updated**: 2025-11-28

---

## 🎯 Purpose

Monitor and ensure the quality, freshness, completeness, and accuracy of data from external OSINT sources to maintain the integrity of political intelligence analysis performed by the CIA platform.

---

## 📊 Data Sources Monitored

| Source | Description | Type | Update Frequency |
|--------|-------------|------|------------------|
| **Riksdagen API** | Swedish Parliament data (members, votes, documents) | REST API | Daily |
| **Election Authority** | Electoral results and party registrations | Data Files | After elections |
| **World Bank Open Data** | Economic indicators and demographic data | REST API | Annual/Quarterly |
| **Financial Authority (ESV)** | Government financial transparency data | Data Files | Annual |

---

## 📈 Quality Metrics Tracked

### 1. Data Freshness
**Definition**: How recently data was last updated  
**Measurement**: Time since last successful data import  
**Targets**:
- Riksdagen API: < 24 hours
- Election Authority: < 7 days (except election periods)
- World Bank: < 30 days
- ESV: < 90 days

**Current Status**: 98.5% of sources updated within target thresholds

### 2. Data Completeness
**Definition**: Percentage of expected data records present  
**Measurement**: Actual records / Expected records × 100%  
**Targets**:
- Riksdagen API: > 99% (349 active politicians)
- Election Authority: > 98% (29 electoral constituencies)
- World Bank: > 95% (key indicators for Sweden)
- ESV: > 97% (200+ government agencies)

**Current Status**: 96.2% completeness across all sources

### 3. Data Accuracy
**Definition**: Percentage of data passing validation checks  
**Measurement**: Valid records / Total records × 100%  
**Validation Checks**:
- Schema validation (data types, required fields)
- Range validation (dates, percentages, counts)
- Referential integrity (foreign keys)
- Business rule validation (e.g., attendance + absence ≤ 100%)

**Current Status**: 99.1% of records pass all validation checks

### 4. Active Alerts
**Definition**: Number of data quality issues requiring attention  
**Types**:
- CRITICAL: Data source unavailable > 48 hours
- MAJOR: Completeness < 90%
- MINOR: Accuracy < 95%

**Current Status**: 2 active alerts

## 💻 User Interface

### Dashboard Sections

#### 1. Data Source Status
Displays real-time status of each OSINT source:
- Source name and description
- Icon indicator
- Status (Active/Inactive/Warning)
- Last update timestamp
- Visual health indicator (✓/⚠/✗)

#### 2. Quality Metrics Cards
Four key metric cards displaying:
- **Data Freshness**: 98.5% (percentage of data within freshness threshold)
- **Data Completeness**: 96.2% (percentage of expected records present)
- **Data Accuracy**: 99.1% (percentage passing validation)
- **Active Alerts**: 2 (number of quality issues)

Each card shows:
- Metric name
- Current value (large, prominent)
- Description/context

#### 3. Navigation
Access via Admin menu:
```
Main Menu → Admin → Data Quality
URL: /cia/#!admindataquality
```
