Nowadays, the management and interoperability of data about learning outcomes (knowledge, skill and competence) are of high importance for both education and employment sectors. By managing and sharing data about their profiles, learners in higher education and lifelong learning can better plan their careers and enhance their employability potential. In order to achieve this goal, the information about learning outcomes associated to units of learning as well as the learning outcomes achieved by learners need to be captured, stored and exchanged in a common format.
