The subsequent development of the CORE system will be achieved through two new projects: ServiceCORE and DiggiCORE. The ServiceCORE project is focused on improving the CORE technical infrastructure, on developing new services including an API for research publications, a subject-based classification system and a good practise for publishing and exposing content in OARs. The DiggiCORE project, which is in collaboration with The European Library aims at the analysis of impact of Open Access research publications by constructing citation networks and analysing research trends. In this respect both projects are complementary. More information about ServiceCORE can be found in the CORE project family section.
