SOPHIE: Use case and evaluation

Learning technology is nowadays subject to intensive standardization efforts that have lead to different specifications defining the functions and information formats provided by different components. However, differences persist and in some cases, the proliferation of proposed standards and protocols leads to increased heterogeneity. Further, the terminologies used to describe resources and activities are diverse, resulting in semantic interoperability problems and conversations between elements that have still not been addressed. The SOPHIE model for semantically describing choreographies has the potential to mediate between these heterogeneous behaviors and representations. This paper sketches the main elements of a mapping of service-based learning technology components based on OKI OSIDs, and provides some examples of mediation based on SOPHIE.
