Trending items

Demian Katz

Obtain lists of items that are currently "trending" (the exact definition of this is open to interpretation – but, for example, items that have recently circulated many times). An API for fetching this type of information could help to power patron recommendations, etc.

In the context of VuFind this would be used to help create a list of suggestions based on what is currently "popular" as determined by the system, to provide serendipity. Historically this might be based on circulation statistics, e.g. most circulated books in a period of time, similar to the "recently returned" shelf. Could be implemented where FOLIO decides what is "trending" or could expose an endpoint where VuFind could formulate a query.
