Abstract

This paper presents the OpenDelos platform implemented in the context of the project “Central Repository of Greek Open Courses”. OpenDelos is an online video editing and publishing platfοrm for online courses, e.g., Massive Open Online Courses (MOOCs). OpenDelos is a unique open source platform that supports not only video on demand functionality but also live streaming functionality along with the related scheduling functionality. OpenDelos is suitable for Higher Education Institutions (HEIs) offering (a) academic roles structure, (b) unique data presentation of the (c) searching and browsing features, (d) hosting of open multimedia and educational content. The main goal of this paper is to present the technical aspects of OpenDelos platform. Τhus, this paper describes OpenDelos’ architecture, modules, and implementation issues. Furthermore, the heuristic usability evaluation conducted by experts during the implementation of OpenDelos platform is presented. The heuristic evaluation showed that OpenDelos did not present major usability problems. Experts’ comments have been taken into account to improve the platform. The improved version is ready and it has been distributed to the end users in order to measure end users’ acceptance towards OpenDelos.
