2. History of the EUDAT CDI
Common Services for heterogeneous communities
Science data rates are exploding and will likely

Building bespoke services for new communities is
not cost effective
Initial Set of Services developed as result of
community needs
Beyond the original ‘core’ communities
New services and specific community issues
highlighted

Infrastructures, how many different data
