So, after a very brief scan of a few sites, I get the impression that:
- Where the aim is to just put up course outlines, lecture slides, handouts, and the like - maybe the occasional multimedia file but no wholesale recordings of lectures etc - something like a prettified dSpace would be quite suitable. For example this is used by Jorum (a JISC-funded service).
- However another factor would be the intended audience for the resources. Jorum seems primarily aimed at educators sharing resources with each other. By contrast, sites aimed at prospective students tend to be more complex, often based on Drupal (an open-source content management system) eg Open University (Drupal/Moodle) or Michigan’s OERbit (open-source software based on Drupal). Of course these also tend to include a lot of multimedia content, especially lectures.
- A third option would be to put material directly into an existing repository - www.oercommons.org, lemill.net, www.curriki.org, cnx.org and many others curate OER. This gets the material out there without having to maintain a platform yourself. But a lot of educational material might make best sense in a national rather than international context (cf OERAfrica)
