Modelling national research information contexts based on CERIF

We present the results of the data modelling in the project 'Research Core Dataset' (2013-2015) that provided the context for developing a set of core definitions for research information for the German science system. In this paper, we focus on the data modelling aspects of the project, whereas another submission focuses on the management of the discussion phase and visualization of the argumentation process in the project. We present how the data model has been developed and synchronised with the argumentation process. As compatibility with CERIF was a major requirement for the data model, we present our approach to link the data model to the CERIF standard.
