MIT’s Open Knowledge Initiative (O.K.I) develops and promotes standards that describe how the components of a software environment communicate with each other and with other enterprise systems through application of Service Oriented Architecture.


eLearning Software Trends

• Service Oriented Architecture

• Focus on Infrastructure

• Adoption of Interoperability Standards

Leading to…

• Flattening of Marketplace

• Increasing Sustainability

• Ease of Collaboration

• Increasing Consumer Choice

The eLearning Marketplace Today - Bound Services

The eLearning Marketplace Tomorrow - Service Factoring


Kinds of Specifications/Standards

• Data Specifications: • Allow systems to have a common understanding of

content being exchanged or accessed

• Protocol Specifications:• Allow machines to talk to each other in a standard way

(provider oriented)

• Interface Specifications: • Allow software components to talk to each other in a

standard way (consumer oriented)


Open Service Interface Definitions (OSIDs)• Interface specification for “Plug-In”

interoperability

• Enable Marketplace of pre-integrated

software components

• Reduce cost and effort for custom integration

• Future-proof against changing technologies

• Increase mobility of applications among

enterprise infrastructures


OSID Status

• Java versions released in Spring 2003• Currently Version 2.0

• PHP versions released Spring 2004• Currently Version 2.0

• Middlebury -- Segue/Harmoni

• Objective-C -- Apple Education Marketing

• C# -- With feedback from Microsoft

• OSID Version 3.0 under development
