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?

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

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

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
