## What is ECHO?

**ECHO is the middleware between Data Partners and Client Partners**
- Data Partners provide information about their Earth science-related data holdings
- Client partners develop software (“clients”) to access ECHO’s metadata using ECHO’s open APIs
- Clients can be customized for a particular user community.
**End users search ECHO's metadata using an ECHO client, and then**
- Access the associated data online or
- Use ECHO’s order broker to order the data from the Data Partner
**ECHO is NOT a user interface, it is the enabling, interoperability middleware**
