Home Defining OER

Platforms, directories and repositories

Another way of organizing or categorizing OER is according to the level of functionality offered by the OER website. For example:

Of course, some organisations and institutions offer combinations of the above functionality, so it is quite possible to find a mix of these functions available within the same OER web site. The following table identifies a few examples of directories, platforms, and repositories. It is worth investing some time to familiarise yourself with the different types of OER offered by each.
