SlideWiki.org is a Web-based OpenCourseWare (OCW) authoring system that enables educators and learners to collaborate on creating, sharing, re-using and re-purposing multi-lingual open educational content.
One of the objectives of the SlideWiki is to allow people authoring FAIR (Findable, Accessible, Interoperable, and Reusable) educational content. SlideWiki supports many features to semantically-enrich educational content to support FAIR authoring. In this paper we will present those features of the platform such as Linked Data interface, manual and automatic content annotation as well as content linking and metadata.
