We need a module that plugs in to Plone to provide multiple file upload. The files uploaded will be assigned as PloneExFile as provided by Ingeniweb's module.
The strategies include:
a. Zip file - However, the complexity is that say zip file has 3 other documents in it, then these documents will need to be extracted for version control and other matters.
b. Single web form with multiple file inputs (not preferred)
c. Java Applet for users to drag and drop files into the browser interface.
If you think you have a better suggestion, we will like to take the best solution that will ultimately be donated back to the Open Source community as a product of Ernitech Consulting Pte Ltd, with full citation of the developer where relevant.
