Open Knowledge Initiative

http://www.okiproject.org/
The Open Knowledge Initiative started at MIT in 2001 with funding from the Andrew W. Mellon Foundation. O.K.I. completed its first phase in July 2003 with delivery of the following:
A set of specifications that define interactions between educational software modules, programs, and systems within and across institutions
Open source code for a reference implementation of each specification, with documentation of the architectural assumptions that underlie the specifications
Open source code demonstrating the application of OSIDs to achieve service level interoperability
