1. Lookup routing information
Request
- Description: The Data Evaluator sends a request to the Connector DR to obtain the Data Owner identifier. A canonical evidence type must be provided, also an optional country code can be specified to obtain the response.

Error handling
- If Data Evaluator cannot be reached there will be a connection error. [DRE01]
- Mandatory fields must be present in the request. [DRE05]
2. Lookup routing information
Request
- Description: The Connector DR sends a request to the Central IAL to get the routing information. The request received from the Data Evaluator is sent to the IAL.
