‘E-portfolio is a digital collection of ‘skilfully made work’ (=lat. artefacts) of a person who wants to document and illustrate the product (learning outcomes) and the process (learning path/growth) of their competence development in a certain period of time and for certain purposes. The person concerned has independently selected the artefacts and organised them in relation to the learning objective. As the owner, he or she has complete control over who, when and how much information from the portfolio may be viewed.’                                         Hornung-Prähauser et al. (2007)
