In video annotation research, the support of the video annotation workflow has been taken little into account, especially concerning collaborative use cases. Previous research projects focus each on a different essential part of the whole annotation process. We present a reference architecture model which is based on identified phases of the video annotation workflow. In a first step, the underlying annotation workflow is exemplified with respect to its single phases, tasks, and loops. Secondly, the system architecture is going to be exemplified with respect to its elements, their internal procedures, as well as the interaction between these elements. The goals of this paper are to provide the reader with a basic understanding of the specific characteristics and requirements of collaborative video annotation processes, and to define a reference framework for the design of video annotation systems that include a workflow management system.
