The chapter starts by discussing the importance of body movement in both music performance and perception, and argues that for future research in the field it is important to develop solutions for being able to stream and store music-related movement data alongside other types of musical information. This is followed by a suggestion for a multilayered approach to structuring movement data, where each of the layers represents a separate and consistent subset of information. Finally, examples of two prototype implementations are presented: a setup for storing GDIF-data into SDIF-files, and an example of how GDIF-based OSC streams can allow for more flexible and meaningful mapping from controller to sound engine.
