This online European Open Science Cloud (EOSC) event was held on 15 December 2021. You’ll get information about: - Developments in the EOSC Association - The work of the new EOSC Advisory Groups and Task Forces - What’s happening in some of the EOSC implementation projects - Ways you can become involved in EOSC

Guiding principles
• The EOSC Future core platform federates existing and new
infrastructures into a system of systems
• EOSC Future delivers the ‘glue-layer’ that allows for the composition of
resources across infrastructures by:
o Providing APIs and metadata
o Providing Interoperability Frameworks
o Providing portal capabilities
• Setup the EOSC-Core
• Populating the EOSC-Exchange
• Technical roadmap is driven by user requirements and implemented as
an, over time increasing in complexity, set of user capabilities

Community Platform
Integrate:
-Resources from EOSC, making them available
to community members: services, data, other
research products
- Core services to add extra basic functionalities
to community platforms
Emerging community
Offer a space for

communities.

Offer discovery of a
comprehensive set of

Key messages
• EOSC Core platform offers value to research communities in different ways
o Enrich community platforms (in the background) with additional resources from EOSC Exchange
and functions from EOSC-Core
o Connect community platforms and foster their greater coherency and increased value
o Offer a comprehensive view of EOSC resources that is also an ‘enterprise bus’ for EOSC catalogues
o Provide a space for experiments in composability and added value services
o Provide a space for emerging / long tail / orphan communities
• EOSC portal is one view on the EOSC Core platform and entries in the EOSC Exchange
o Web based view
o Also API based access to Core platform from tools, workflows etc
• The view of EOSC as a set of platforms forming a system of systems is better supported by communities
• We should shift from focussing on the portal to the platforms
and see the portal as useful element but not a single point of entry
