Was: https://www.umms.med.umich.edu/it.jira/browse/OERDRUPAL-99

To provide more useful information for our users, we should be able to point them to other relevant OER/OCW related to the topic of interest.

this is something that could be played with - need to see if it produces relevant results.

Folksemantic no longer exists. We decided against including recommender systems in OERbit and focus on learning registry instead. I think it's OK to close/cancel this issue.
