In Zarela’s ecosystem, there are three distinct players with specific roles. They are Angels, Mages and Hubs. At Zarela, a Mage must provide a structured explanation about the underlying research project in order to be able to communicate with Angels through the Hubs. Z-paper is a simple but comprehensive document that should be submitted to Zarela’s platform by Mage. Thus, if a research project does not convey an obvious goal in its Z-paper, it is less likely to be able to collect data sets. So, a well described Z-paper would explicitly define participants’ roles in the research project as well as making sure the research project follows solid goals.
