Yes, this is correct. Is this what you are already doing?

To give some background: the fileResource functionality is at this point
only supported as a backend for File dataValues, and not really as a
generic storage mechanism for files. The reason for the two-stage process
is that the server needs to perform processing and (potentially)
re-uploading of the file (depending on the storage backend used) before it
can be stored as a DV.

In the bundled data entry apps (tracker and aggregate) we do this by a
three step process:

1) upload the fileResource to api/fileResource and retrieve the returned
uid.
2) POST the DV with the value=<fileResource-uid>
3) (optional) Poll the fileResource/<uid> endpoint for the status of the
upload to ensure it is properly stored in the backend.

Fetching the actual file back can thus only be done on the
api/dataValues/files endpoint (with query params just like on any
DataValue).
