Hi,

To be 100% clear:

If a standard set of documents are to be uploaded - as is the case here -
we simply need to create one text data element for each type of document to
store the UID returned with the response field? There is no need for any
other data values to reference the stored file?

If uploaded documents are NOT standard (e.g. if you asked users to upload
let us say a number of photos), you will still need to create x data
elements to store the UID references to whatever is uploaded?

What if you want multiple data value records to reference the same document
- e.g. one with the doc UID, another with the date of the upload, and a
third a boolean data value indicating how many times the document has been
accessed. In that case, what is the exact construct used to link the
document to the other fields? (this is just for my own understanding of the
design).

Regards
Calle
