# Tagging Guidelines

Consistent tagging makes content discoverable across the Hub. This chapter defines the standard tags for World Bank geospatial content.

```{tip}
Tagging standards may evolve as the World Bank's geospatial data governance framework matures. Check back for updates.

## Why Tagging Matters

Tags enable:

| Function | Benefit |
|----------|---------|
| **Search** | Users find content by keyword |
| **Filtering** | Category views show relevant subsets |
| **Organization** | Related content groups together |
| **Analytics** | Track content by theme or sector |

## Tag Categories

### Required Tags

Every item should have tags from these categories:

| Category | Purpose | Examples |
|----------|---------|----------|
| **ISO3 Country** | Geographic scope | `NGA` |

### Recommended Tags

| Category | Purpose | Examples |
|----------|---------|----------|
| **Scorecard** | WB outcome areas | Aligned to WB Scorecard indicators (see your country team for current list) |

## Tagging Standards

### Format Rules

| Rule | Example |
|------|---------|
| Use lowercase | `health` not `Health` |
| Use underscores for multi-word | `foundational_data` not `foundational data` |
| Use ISO3 codes for countries | `NGA` |
| No special characters | Avoid `&`, `/`, `#` |

## Applying Tags in AGOL

1. **Open the item** in ArcGIS Online
2. **Click Edit** on the item details page
