The ESCAPE Data Infrastructure for Open Science (DIOS) is a service from ESCAPE EOSC (European Open Science Cloud) thematic cell, a cross-border and multidisciplinary virtual research environment of ESFRI (European Strategy Forum on Research Infrastructures) projects in the astro- and  particle physics domain.

ESCAPE DIOS is a federated data infrastructure of open access data that enables large national research data centres to work together and build a robust cloud-like service to curate and scale up to multi-Exabyte needs. The ESCAPE DIOS is a flexible and robust data lake in terms of storage, security, safety and transfer, as well as basic orchestration machinery, which enables the combination of technology with high quality data from different communities and, therefore, the exploration of new areas in science. It is a pillar infrastructure to be connected to EOSC, address the next decades’ data challenges and serve the international user communities.

ESCAPE DIOS will hide the complexities of data management and data access in a distributed environment from the end users. It provides capabilities for managing large volumes of data and making them accessible to very distributed communities, while optimizing the cost of storage.

In the webinar "ESCAPE DIOS | A federated data-lake to connect large data volumes from different communities - benefits & use cases" we will show the ESCAPE DIOS developments and achievements, by sharing testimonials from some of the ESFRIs (European Strategy Forum on Research Infrastructures) which are being supported by ESCAPE in facilitating their interdisciplinary research.

For example, the webinar will count with KM3NeT testimonial, a neutrino telescope under construction in the deep waters of the Mediterranean Sea, and is already operational 24/7. In this presentation, we will understand how the ESCAPE DIOS infrastructure can be used for KM3NeT data management. This infrastructure will be adopted to serve as a data management and data access system for the distributed KM3NeT community. LSST will present how leverages the ESCAPE platform for preparing the data replication infrastructure for its needs. LOFAR will present the use cases and the corresponding data workflows for the currently operational international LOFAR radio telescope. LOFAR will present similarities and differences between data workflows for radio astronomy and the particle physics domain for which the Scientific Data Lake was originally developed.

Who should attend?

  • Scientists from any scientific field that want to manage large volumes of data and make them accessible to very distributed communities, while optimizing the cost of storage;
  • Professionals from e-infrastructures and research infrastructures, from Europe and beyond, looking forward to developing innovative technologies and increasing international cooperation on global interoperability and access;
  • Professionals involved in the EOSC working on ensuring the optimal federation of ESFRI clusters/ RIs with EOSC.
