Massachusetts Institute of Technology Page 2 Elements of an enabling architecture/framework for learning systems What are strategies for interoperability, scalability, and maintainability? How might we migrate from an environment based on proprietary legacy tools to a standards-based environment that promotes interoperable systems? What are the requirements for development/authoring tools that enable rapid prototyping, ease of maintenance, content adaptation, and collaborative development?

Massachusetts Institute of Technology Page 3 Elements of an enabling architecture/framework for learning systems What is the impact of emerging specifications and standards (e.g., XML, SCORM, IMS, OKI SPECS, the semantic Web.....) on IT-enabled learning, and on managing rapid changes in the technology/tools environment

Massachusetts Institute of Technology Page 10 O.K.I. Service Interface Definitions (OSIDs) OSID's define how components of a learning technology environment communicate with: Other learning technology components Other campus systems Common infrastructure services OSID’s are: Described abstractly and cast as Java APIs Royalty free Stable – license/branding prohibits modification Supported by reference implementations and documentation

Massachusetts Institute of Technology Page 17 OKI Digital Repository OSID What functions do Educational Applications need from Digital Repositories? How can we complement existing and future data Specifications? How do we allow for systems of record for learning assets? How do we support multiple Repositories with multiple protocols
