I just poked through Rory’s A Typology of Learning Object Repositories article, starting with the tables, and found a few errors relating to his description of CAREO. Here are the corrections (I don’t have Rory’s email handy, and there aren’t comments on the DSpace page for the article):

•  CAREO supports hosting content as well as linking to other servers. That was one of the primary goals of the project – to allow people to easily post content without having to know FTP. I don’t have the stats on this, but about half of the items in CAREO were uploaded to the CAREO server via the “add object” form.
• For “maintaining” an object – CAREO lets the owner of the object edit the metadata, including replacing the media with an updated version.
• CAREO does allow retrieval of metadata – there’s a “metadata” button on every object – which shows up once you are logged in.
• CAREO requires an account to submit objects, but anyone can create an account.
• The metadata schema used was IMS LOM (and later IEEE LOM).

But, it’s all a bit moot, as institutional and provincial support for the CAREO repository evaporated long ago, and the application itself is on its last legs. It’s no longer supported, is barely functioning at the moment, and will be decommissioned at the end of the month.
