What Is EPrints
Let's get away from the OAIS definitions and repository talk. Let's think about EPrints as an abstract information system. WHat features does it provide, so what classes of problem can it be used for?
Acquisition
Perhaps primarily, EPrints is a tool for getting information from people. It has a very good interface (though we say so ourselves) for helping people enter quite complex information in as accurate amnd complete a way as possible, and it is very flexible about what kind of information can be entered and how.
You can use it for anything you want to capture from people: coursework handins, conference submissions, blog entries, summer holiday photo snaps, MP3 or video collections, questionnaires, workshop registration or credit card details. Or there's the more obvious repository candidates: scientific data, published documents, student portfolios, fine art exhibitions.
