Workshop “Virtual Research Environments: What Services Should They Offer And What E-Infrastructures Should Provide To Support Them”, 27-28 February 2018, CNR Pisa There is a growing interest in Virtual Research Environments (VREs, also named Science Gateways or Virtual Laboratories) as instruments to support research communities in cooperating and performing their scientific activities. Several VREs are now operational and a number of VRE frameworks have been developed to facilitate their creation. All these components rely on services provided by underlying e-Infrastructures.
