Simple learning design 2.0

Simple Learning Design 2.0 (SLD 2.0) is a learning design specification proposed by Durand and Downes from the National Research Council of Canada in 2009. SLD 2.0 is designed to be easily implemented by developers in a commercial e-learning application. The intent behind SLD 2.0 was to propose a specification with a good balance between its expressivity and the simplicity of its implementation; all features that might have been deemed too complex to implement were systematically avoided." SLD 2.0 can be used as an add-on to IMS Common Cartridge, respecting and reusing the features of IMS-CC. To implement the specification an XML schema is available online (here) and explained in the XML Binding Document.
