Different cloud storage services use their own unique terminology to refer to document storage concepts. The SimpleCloud API defines a number of common concepts that are shared among all major providers.
The storage service identifies files by string keys, which may be URL paths or another service-specific identifier. The items can be stored and retrieved using this key. Each item can have metadata associated with it. These metadata carry service-specific information about the item, such as size, type, permissions, etc. as defined in the adapter for that provider.
