We are Elrha, a force for change in the humanitarian community. The research and innovation we support equips the humanitarian community with the knowledge of what works, so people affected by crises get the right help when they need it most.
Our purpose is clear: to empower the humanitarian community to improve humanitarian response. We make this happen by supporting and championing the outcomes of robust research and proven innovations.
We empower the humanitarian community. Find out how we can support you...


  • Current data for planning and decision support is hard to find during a crisis.
  • Data becomes fragmented and isolated in individual partners’ systems.
  • Prior attempts that focused on building centralised databases or standardised forms have had limited success.


This is primarily a process innovation for relief coordination and support services, involving a new, decentralised, consensus-based approach for collecting and sharing data across a network of humanitarian partners.

Innovation Phases Description:

  • Form a working group to lead the standards effort, with broader outreach to all members of the humanitarian community through mailing lists and other collaboration channels.
  • Deploy a technical team to prototype and implement the agreed standards and technical infrastructure in up to two small-scale field pilots.
  • Coordinate these groups (working group, technical team and broader community) as they work iteratively towards a consensus version 1.0 release of the HXL standards and recommendations.


  • Make better data available to support crisis-response planning and action.
  • Improve efficiency by reducing the manual work of collecting crisis data.
  • Allow each organisation to remain a custodian of its own data.
  • Build a long-lasting open data ecosystem that bridges the disaster-management and development cycles.
  • Open up humanitarian data to a wider group of actors, tapping into the potential of the crowd to support humanitarian response.

The Humanitarian Exchange Language Reaches Alpha

20 Oct 2004

The HXL Working Group is proud to announce the alpha release of theHumanitarian Exchange Language (HXL). Inspired by social-media hashtags, HXL is a simple standard that adds hashtags to spreadsheet headers to make it easier to share and compare humanitarian data.


Introducing HXL hashtags for humanitarian data

20 Aug 2014

The members of the HXL Working Group have focused on stripping layer after layer of complexity from the proposed Humanitarian Exchange Language (HXL) standard, until we finally asked ourselves whether labelling information in shared data could be as simple as tagging topics is in social media posts.


Starting Work on the Humanitarian Exchange Language Initiative

10 Mar 2014

Thanks to support from the Humanitarian Innovation Fund, we have started building standards for sharing data among the groups involved in crisis response.
