HDX HAPI: Standardized Humanitarian Operational Presence (3W) Data

Delivering standardized humanitarian operational presence indicators (3W/4W/5W) sourced from the HDX Humanitarian API (HAPI) as of March 2026. Maintained by the HDX Humanitarian API Data organization, it aggregates multi-source data to track which organizations are performing specific activities in various locations. The data is formatted for interoperability using the Humanitarian Exchange Language (HXL) standard.

Use Cases

• Mapping humanitarian 'Who is doing What, Where' (3W) using operational presence indicators
• Automating humanitarian decision-making workflows via HXL-tagged data structures
• Analyzing data quality and reporting patterns in humanitarian aid using the provided warning and error flags

Strengths

• Standardized via HDX HAPI for seamless interoperability across multiple sources
• Includes HXL (Humanitarian Exchange Language) tags for automated processing
• Transparent error reporting including rows with warnings and errors for data auditing

Limitations

• Specific column names and row counts are not provided in the source metadata
• Rows with errors are included for transparency but are considered unusable for standard analysis
