 ### Pod Organization
-Data that is stored in Solid pods is organized in containers and resources. Access can be granted to containers and resources. But in order to find data back and not to share too much information to an application, we propose an organisation structure of data in the pod as follows. The structure follows the resources definitions from [FHIR](https://www.hl7.org/fhir/resourcelist.html).
