The following are simply my opinions. I hope others comment as well on this thread and we get these resolved.
organization.uri: yes I think it should be named uri
organization.tax_status and tax_id: yes I think deprecated
organization.id: yes I think it should be the same as the other fields
service.wait_time and fees: yes I think deprecated
location.location_type: I think location_type is there to signal whether the address is physical or virtual, and address_type is to define whether the address is a physical office people can visit or just a postal address – so I think we need both.
required_document: should have a uri that could be called “link” or “path”.
