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.[1] It was intended as an interoperability specification, simpler to implement than IMS Learning Design, a specification as of 2010 restricted only to pilot and research projects.[2] IMS Learning Design is a specification for describing methods of learning design, in a way that claims to be pedagogically neutral. Simple Learning Design 2.0 was designed to be implemented by developers in a commercial e-learning application,[citation needed] and was intended to be paired with a more complex specification, described as "a real UML for learning design."[2] The intent behind SLD 2.0 was to propose a specification with a good balance between its expressivity and the simplicity of its implementation.[3]
