ISO/TS 16058:2004 addresses the technical and system components of the telehealth reference architecture for telelearning systems. It does so by defining technical requirements to be satisfied for a compliant telelearning system. A compliant system will help to ensure that the telelearning technologies deployed for healthcare telelearning are capable of appropriately supporting and delivering distance learning as well as interoperating with disparate telelearning systems that are also compliant with this specification.
