WP2 - Data Infrastructure for Open Science (DIOS)

Lead participant: CERN
WP2 leader: Simone Campana

WP2 DIOS will design, implement, and operate a prototype data lake – a federated data infrastructure that will form the basis of an open access data service for the ESFRI projects within the ESCAPE cluster. It will propose such a solution as a key component of a future EOSC framework. The data lake concept enables the large, reliable, national research data centres to work together to build a robust cloud-like service to curate and serve data of CTA, FAIR, EGO-Virgo, HL-LHC, JIVE, KM3NeT and SKA at all scales up to the multi-Exabyte needs of such projects. These data centres (CERN, CNRS-CCIN2P3, DESY, GSI, IFAE-PIC, INFN, LAPP-MUST, Nikhef, SURFSara, UG), partners in ESCAPE, have experience built up over a decade in particle physics within WLCG and in supporting major astronomy and astroparticle physics precursors pan-European research infrastructures (such as AMS, ANTARES, HESS, LOFAR, MAGIC, etc.).

Key outputs: A mechanism required for large research infrastructures such as HL-LHC and SKA that in future will manage multi-Exabyte data sets, that will need to be served to global user communities in a scalable and performing way. A federated storage infrastructure implementing the FAIR data management principles at the base level, and form the basis for higher-level data preservation and access services delivered in the other work packages.
