This deliverable is reporting on the progress on the construction and integration of the Generic Execution Framework (GEF), as well as additional required tools and components. The focus is on any lessons learned from the first stage of technology adaptation and construction. It describes how existing EUDAT user technologies have been incorporated, including any necessary adaptations. It also suggests expected behavior of the framework against User Community needs. The final report (D7.5.2) will describe and assess the EUDAT GEF, including any adaptations that were necessary to accommodate the requirements of the user communities.
