3. European Open Science Cloud
It aims to accelerate and support the current transition to more effective Open Science and Open Innovation in the Digital Single Market
It should enable trusted access to services, systems and the re-use of shared scientific data across disciplinary, social and geographical borders

4. EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania
Open Science
Necessary condition:
Faireness of data, tools, services, worksflows
Support to producers
creating, depositing, publishing and preserving
Support to consumers
finding, accessing, interoperating and reusing
Desiderata: Accellerate and reduce the cost of science and innovation
Where possible, the EOSC should enable automation of data processing and thus machine actionability is key
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

5. Key Factors for the effective development of the EOSC as part of OS
The EOSC needs to be developed as a data infrastructure commons, that is an eco-system of infrastructures Build on existing capacity and expertise where possible
New modes of scholarly communication (with emphasis on machine actionability) need to be implemented
Where possible, the EOSC should enable automation of data processing and thus machine actionability is key

System-of systems
Operational and managerial independence
each system is independent and it achieves its purposes by itself and for its own objective rather than for the purposes of the SoS
Geographical distribution
a SoS is distributed over a large geographic extent
Emergent behavior
a SoS has capabilities and properties that do not reside in the component systems
Evolutionary development
a SoS evolves with time and experience
Heterogeneity of constituent systems
a SoS consists of multiple, heterogeneous, operating systems embedded in networks at multiple levels
Components:
Exiting and emerging RIs, e-Infras, data repositories, registries,…

7. As-a-service provision mode
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

8. Service characterization
Functionality
Operational state(*)
Usage regulating policies
Quality of service
......
We expect that every service that will populate EOSC will provide at least a descripton of itself.
(*) particularly relevant for data, workflow, sw repositories
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

9. Service classification
KaaS (Knowledge as a Service)
AaaS (Application as a Service)
DaaS (Data as a Service)
SaaS (Software as a Service)
PaaS (Platform as a Service)
IaaS (Infrastructure as a Service)
Support to the EOSC user
Support to the EOSC user
F and G might be further specialised

Levels of engagements
Publish service description in the service catalogue with an agreed metadata formats
Describe rights and licences, provenance, metrics, etc. according agreed standards
Publish resources with a specific range of policies
Implement common protocols
Ensure a given SLA ……
The above are examples of different levels of engagement

11. Facilitating Open Science Enabling and operating the federation
EOSC services
Facilitating Open Science
(complementing and enriching existing initiatives)
Services enacting the operation of the “federation”, i.e. basic services conceived to support the development and operation of EOSC as a system of systems;
Services enacting Open Science, i.e. a set of services aiming at simplifying the “publishing, finding and re-using each other's data and tools for research, innovation and educational purposes”
Enabling and operating the federation
(according the established rules of engagements)
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

12. Facilitating Open Science: Findability
Service catalogue
where all the constituents’ services are seamlessly published, described and discoverable
Other catalogues, e.g. data, publication, sw/method, workflow catalogues
 PID provider
Metadata validators
Subscription and notification
Recommender system …
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

13. Facilitating Open Science: Accessibility
Research Object Repository
Appropriate metadata catalogues
Identity federation and delegation
Access protocols mediators
…..
A1  (meta)data are retrievable by their identifier using a standardized communications protocol. A1.1 the protocol is open, free, and universally implementable. A1.2 the protocol allows for an authentication and authorization procedure, where necessary. A2 metadata are accessible, even when the data are no longer available.
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

14. Facilitating Open Science: Interoperability
Set of “mediators”
unifying (standard-based) services / APIs enabling EOSC services consumers to interface with homologous services or classes of services offered by different providers
Metadata and data format mappings
Legal compatibiity
…….
Services for preservation: temporal interoperability
EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania

15. Facilitating Open Science: Reuse
Virtual Research Environments/Virtual Laboratories/Science Gateways Creation and Operation, i.e. Facilities for exploiting services, data, workflows in different environment scopes (across domains, infrastructures, geographic boundaries)
“Research Objects” Creation, Publishing, and Exploitation 
Support to automatic citation /provenance …

16. EGI Conference 2017 and Indigo Summit 2017, 9 May 2017, Catania
Open issues
What should /can be the initial EOSC architecture?
Level of facilities
Agreed rules of engagement
Deployment architecture
Who will host and operate the EOSC specific services? EOSC entity? Certified service providers?
How will common services (e.g. catalogues) be built? Will part of them be operated by component infrastructures?
….. and many others
