Middlebury College's Curricular Technology group has been developing curricular applications since 2003 when it first released Segue as open source.  In addition to Segue, this group has also developed Concerto, a digital assets management system and Harmoni, an application framework that includes implementations of nearly all the O.K.I. OSIDs.

In 2007, Middlebury College received a Mellon Award for Technology Collaboration for this work.
