Mediate is a collaborative video annotation tool developed by River Campus Libraries and Professor Joel Burges (English and Visual and Media Studies). Mediate has entered the second phase of development. Based on student feedback, Josh Romphf has made substantial changes to the user interface. In the coming months, we look forward to working with Sean Morris and Nate Sarr (IDT) as we develop the admin interface. While Mediate will likely find broad use for those interested in visual and digital media studies, there has also been interest from UofR faculty in education and linguistics. Mediate allows for groups of researchers to collaboratively annotate, query, and visualize temporal media. The project is currently in the alpha stage, and is built with Django, OpenCV, PostgreSQL, and ReactJS.
