The Open Knowledge Initiative (O.K.I.) develops and promotes specifications that describe how the components of a software environment communicate with each other and with other enterprise systems. O.K.I. specifications enable sustainable interoperability and integration by defining standards for Service Oriented Architecture (SOA). Through this work O.K.I. seeks to open new market opportunities across a wide range of software application domains.

The O.K.I. project was initially launched in 2001 through a generous grant from the Andrew W. Mellon Foundation, and in collaboration with a number of like minded organizations.  Today the O.K.I. Phase II project is housed at the Office of Educational Innovation and Technology, a part of MIT's Dean of Undergraduate Education Office.
