The first Version of a Backend should have:

• Persistent data management

  • Structural data is stored in database
  • File data is stored on the backend (AWS-S3 bucket)
  • All entities should be deletable (e.g. delete Project, delete File, delete Visualization)
  • Stored files and metadata should be in sync all the time

• Authentication and Authorization in place

  • all components must require oauth-authentication
  • all components must enforce proper authorization in terms of ACL (access control lists) the file server is managing these ACLs
  • The project must support public (not logged in users) content. In this case clients don't need to aquire access tokens
