Abstract: The act of note-taking is an essential part of the data analysis process.It has been realized in form of various annotation systems thathave been discussed in many publications. Unfortunately, the focususually lies on high-level functionality, like interaction metaphorsand display strategies. We argue that it is worthwhile to also considersoftware engineering aspects. Annotation systems often sharesimilar functionality that can potentially be factored into reusablecomponents with the goal to speed up the creation of new annotationsystems. At the same time, however, VR-centered annotationsystems are not only subject to application-specific requirements,but also to those arising from differences between the various VRplatforms, like desktop VR setups or CAVEs. As a result, it is usuallynecessary to build application-specific VR-centered annotationsystems from scratch instead of reusing existing components.To improve this situation, we present a framework that providesreusable and adaptable building blocks to facilitate the creation offlexible annotation systems for VR applications. We discuss aspectsranging from data representation over persistence to the integrationof new data types and interaction metaphors, especially in contextof multi-platform applications. To underpin the benefits of such anapproach and promote the proposed concepts, we describe how theframework was applied to several of our own projects.
