CopperCore Service Integration - Integrating IMS Learning Design and IMS Question and Test Interoperability

This article describes a framework for the integration of e-learning services. There is a need for this type of integration in general, but the presented solution was a direct result of work done on the IMS learning design specification (LD). This specification relies heavily on other specifications and services. The presented architecture is described using the example of two of such services: CopperCore, a LD service, and APIS, an IMS question and test interoperability service. One of the design goals of the architecture was to minimize the intrusion for both the services as well as any legacy client that already uses these services
