Hi everyone,

I've been reading up on the Learning Registry recently, which is a
distributed system for learning resource metadata that includes both
"regular" descriptive data and usage data ("paradata") such as
reviews, downloads and ratings.

E.g., the following gets information about a resource (something about
KC-135 tanker aircraft) and also paradata that asserts 73 views and 11
downloads:

https://node01.public.learningregistry.net/obtain?request_id=http://3dr.adlnet.gov/api/rest/adl:748/Format/dae?ID=00-00-00

The interesting thing is that multiple "repositories" can publish this
data to a LR node, and that LR nodes can share this data in a
network.

So in our case we might have a network of LR nodes for widget
metadata, which is contributed to by ROLE, ITEC and OU widget stores,
meaning we could pool the usage metadata to improve recommender
performance.
