EUDAT provides a suite of data services to support European researchers, including B2ACCESS which enables single sign-on access to EUDAT services using various authentication methods, and B2DROP which allows researchers to securely store, share, and synchronize research data in the cloud. The services are developed based on community requirements and aim to help researchers manage their data across European research institutions through a collaborative data infrastructure.

12. EUDAT overview

13. • A pan-European initiative building a sustainable
cross-disciplinary and cross-national data
infrastructure providing a set of shared services for
accessing and preserving research data
• Close collaboration with research communities to
optimally support their data management needs
and deliver the appropriate technical services
EUDAT - European Data
Infrastructure

14. A truly pan-European
Infrastructure
EUDAT offers common data services,
supporting multiple research communities as
well as individuals, through a geographically
distributed, resilient network of 36 European
organisations
Our vision is to enable European
researchers and practitioners
from any research discipline to
preserve, find, access, and
process data in a trusted
environment, as part of a
Collaborative Data
Infrastructure

15. EUDAT Vision & Mission
● Vision: Data is shared and
preserved across borders and
disciplines thereby enhancing the
value and quality of research at
large.
● Mission: To enable data
stewardship within and between
European Research Communities
through a Collaborative Data
Infrastructure, a common model
and service infrastructure for
managing data spanning all
European research data centres
and community data repositories.

16. What is the EUDAT CDI?
• The EUDAT CDI is a collaboration
between Service Providers and
Research Communities working as part
of a common framework for
developing and operating an
interoperable layer of common data
services
• Generic Service Providers have
regional, organisational or national
mandates to support scientific
research, usually from different
disciplines.
• Thematic Service Providers are
(discipline-specific) organisations
mandated to support a
well-defined scientific community
or group of users.

Where is B2FIND in the EUDAT suite?
B2FIND
• stores metadata
through other EUDAT
services such as
B2SHARE to provide
access to data
objects within the
EUDAT CDI
• is used in inter-service
use cases, e.g. to
identify links to data
collections, which will
be transferred to HPC
platforms through
B2STAGE

71. b2drop.eudat.eu
With B2FIND you can...
B2FIND – Find Research Data
• Browse through the large amounts of
data that EUDAT stores from a broad
range of disciplines
• Search the whole catalogue, which
comprises collections of scientific
data, irrespective of their origin,
discipline or community
• Carry out faceted searches for
• geospatial or temporal coverage
and
• textual properties, such as
‘Creator’ or ‘Publisher’ and many
other facets
• Find and access scientific data
objects relevant for your work

72. b2drop.eudat.eu
Data from a
great selection of subjects
B2FIND has a truly cross-community
approach
• Metadata are harvested from a
wide range of research areas
• From Climate Research to
Social Sciences
• From Biodiversity to Linguistics
• From Archaeology to
Seismology
• This necessitates the transformation
and homogenisation of the diverse
metadata to achieve the usage of
a common vocabulary for the
whole catalogue This image is licensed under the Creative
