Summary: Using HTML5 for File Upload in XMLUI
Key: DS-1562
URL: https://jira.duraspace.org/browse/DS-1562
Project: DSpace
Issue Type: New Feature
Reporter: Pascal-Nicolas Becker
Currently files get uploaded using a html form. This has some major flaws for
example if a transmission breaks the hole file has to be uploaded again, the
size of files that can be uploaded this way is limited and you can only upload
one file at once.
HTML5 File API allows to define an element (f.e. a div-element) that can be
used to drag and drop files on it. HTML 5 although can cut files in slizes.
With this feature set it is possible to overcome the faults specified above. It
is possible to drag and drop several files at once. With JavaScript every File
will be sliced into chunks and each chunk will be transmitted seperatly. If a
transmission fails only the chunk that was submitted has to be retransmitted.
When all chunks got transmitted correctly the chunks have to be reassmbled on
the server.
