It compares and contrasts them with the requirements of European research communities, in particular the High-Energy Physics and Radio Astronomy fields, with a focus on the use cases described in Spectrum Deliverable D5.1 (Representative use cases: analysis and alignment), and identifies and discusses recommendations for the future evolution of the e-Infrastructure landscape in Europe.
