Dear Andrea Thank you for your inputs and references. It really encourages me. I really appreciate it. I also thought of ranking or way to review skills and work achievements by peers. Maybe a combinations of several peer students review, several mentors review and or organizational reviews. These I imagined will be the future of certification/diplomas, something that is more organic, real, accreditations that is more human oriented not institutionally dictate. We definitely can work towards the detail if the platform is going to be realized.
