Event Information

Most sources return information about each individual event (citation, bookmark, etc.), and this information is summarized below. The exception are sources that don't return information about individual events because of privacy (all usage data, Facebook, Mendeley readers) or for licensing reasons (Scopus, Web of Science, F1000).

Creating a new source

Basically, each of the APIs that the ALM application is calling will be defined as a source. The ALM application provides a number of services to each source to help it get what it needs. Note the samples provided at http://github.com/articlemetrics/alm/tree/master/app/models/sources.
