WebLD: A Web Portal to Design IMS LD Units of Learning

This paper presents WebLD, a web authoring tool to create units of learning following the IMS Learning Design (IMS LD) specification. WebLD presents two main features that distinguish it from other tools: (1) it is a web application, therefore available anytime, anywhere from the Internet, and (2) it includes semantic technology, based on our IMS LD ontology, that enables the automatic validation of IMS LD documents.
