I explained how we overcame the technical challenges preventing our depositors from sharing bigger files by adding HTML5 upload to our DSpace repository (Edinburgh DataShare) allowing upload of files up to 15 GB and even 20 GB in some circumstances. These slides also explain our plans to link up an FTP server to Edinburgh DataShare to make it convenient for users to download filesets of around 10 GB and possibly even bigger. Unfortunately I hit my 7-minute limit before I had a chance to get to the FTP bit. Thank you Slideshare for allowing everybody to find out what was in the rest of my talk!
The code for the HTML5 upload is at https://github.com/edina/DSpace/tree/xml-html5-upload . This 7-minute presentation ("24x7") was given at Open Repositories 2016 on the 14th of June 2016. The full abstract is at: https://www.conftool.com/or2016/index.php?page=browseSessions&form_session=126
N.B. the 20 GB file which I have uploaded, and which is our current upper size limit, is 20 GB in the strict sense of the word i.e. 20 x 1,024 x 1,024 x 1,024 bytes. In Linux this is displayed as 21,474,836,480 (bytes) whereas in Windows the size is usually expressed in KB i.e. 20,971,520 KB.
