VRE4EIC Deliverable 3.4 Enhanced VREs

This deliverable provides the results of two tasks within WP3 of the VRE4EIC project: Task 3.4 "Integration of Reference VRE and Enhanced Existing VREs" and Task 3.5 "Design and development of a GUI for eVRE". In particular: The enhanced VREs are extended implementation of the EPOS and ENVRIplus VREs which have been obtained by migrating the architectures of these VREs into new architectures that includes building blocks developed by the VRE4EIC project, in the context of task 3.3. The resulting architectures provide the involved VREs with additional functionality that extends their capabilities in significant ways for the underlying research communities, while at the same time prove the functional and technical validity of the Reference Architecture developed (D3.1) and implemented by the project. The eVRE GUI provides eVRE with an access point for the human user, thus addressing the usability of VREs, which is one of the main goals of the project. In addition, the present deliverable provides the Canonical Reference Prototype (CRP) of the Reference Architecture, also produced by Task 3.4 of the project by integrating existing technologies to implement the components of the Reference Architecture. The realization of the CRP has required the development of a Technical Architecture, which complements the Reference Architecture by selecting a set of suitable implementation techniques and open- source components.
