Eprints.org has released IRStats, an open source use statistics analysis package that analyzes both EPrints (versions 2 and 3) and DSpace (beta functionality) logs. The software is under a BSD license, and it requires Perl, awstats, MySQL, Maxmind Organisation Database, ChartDirector, and a CGI-capable Web server.
A description of IRStats features is available as well as examples of its use. For additional information on the project, see "Introduction to IRS."
