PrestoCentre Preservathons are two-day hands-on events developed around main themes and challenges in audiovisual digitisation, preservation and long-term access. During the first day, attendees will work together in small groups. Activities include workshops, roleplaying, demonstrations, presentations, writing and negotiation exercises (e.g. call for tender, SLA). Each Preservathon includes a competitive element. The second day is organised as a mini-conference including concise presentions and demonstrations of the results and experiences from the first day, a ceremony to award the winning group, and a short but informative review on the subject, incuding the state of relevant technology, related research, and open questions.
