From MemoRekall to MemoRekall-IIIF: developing a video annotation web application in the context of citizen science co-creation practices

MemoRekall is a free and open-source web app to annotate a video enhanced by adding notes, documents, or web links. Originally conceived for the preservation and documentation of performing arts, two European citizen science projects (COSMIC and COESO) lead to broaden its uses and develop new functionalities. Both projects share the same methodological approach, based on action research and co-design. This paper will present this co-construction methodology, at the heart of MemoRekall's development from the outset, how it impacted the two new versions of MemoRekall, and its contribution to the study of collaboration in the context of citizen science projects.
