Enable users to migrate/copy their accounts to another server

[dmitrizagidulin]

Develop an API/workflow recommendation for users to be able to securely migrate or copy their account (and potentially all of its data) to another Solid server or compatible service provider.

Considerations:

• What should the workflow be, for authorizing the copying (via "pull") of the data to another server?
• What should the UI look like, for selecting which data / containers the user wants copied?
• The old server/solid provider should be able to redirect (via HTTP 301, etc) links to the old account's data to the new one. See http://www.w3.org/TR/cooluris/ etc.
  • This policy should be encouraged, but will ultimately be determined by the service provider. Need to discuss how the service provider should signal this in their terms of service.
