2. To define a reference architecture
The goal
A ref. arch. models the abstract architectural elements in the domain of interest independent of the technologies, protocols, and products that are used to implement a specific solution for the domain
It shows what is involved in realizing the modelled entities, while staying independent of any particular solution but instead applies to a class of solutions
To define a reference architecture
A ref. arch. is not a concrete architecture
It generally specifies components and their relationships in sufficient detail but it does not enable direct implementation and deployment

3. Characterised by the Emergent Behaviour
The domain of interest
EOSC must be
a facilitator of Open Science processes
federated and globally accessible across disciplines and geographical borders
inclusive to build on existing capacity and expertise
ensure a large degree of freedom regarding implementation
It has to be more than the sum of the aggregated systems

6. 6 Actor Roles
Use functions and tools to perform their domain specific research activities and to collaborate
Develop new analytical models, new processes and tools to analyse data and derive knowledge
Develop services for scientists by understanding their requirements and the Open Science vision
Operate and provide access to their own portfolio of services according to declared SLAs
Provide access to computational, storage and network resources, according to declared SLAs
Facilitate the operation, assistance and quality assurance of the EOSC system and the coordination among its different stakeholders

7. 6 Actor Roles These users
operate with different types of resources and
demand different services and working environments
Scientists and developer scientists need services to produce research artifacts (including methods and tools) and need virtual research environments to support their multidisciplinary collaboration
Developers of services often demand for access to appropriate platforms, including those providing facilitated access to computational and storage resources
These user operate with different types of resources and they demand different services and working environments.

The identification of the EOSC services is intended to be an iterative process that will evolve
through the requirements received from the demonstrators
with the evolution of the other elements that are involved in its development, like rule of engagement, incentives and rewards, policies, and governance
For the set of necessary services identified, it is not yet specified who will be the service provider that will operate and delivery these services

11. Resources
The European Open Science Cloud for Research pilot project is funded by the European Commission, DG Research & Innovation under contract no

12. Abstract Class of Resources
Scientists research asset / artifacts inclusive of papers, datasets, scientific software, scientific workflows, notebooks, compound “research objects” virtual research environment specifically set up for supporting any research question / endeavor / goal
Developer Scientists
scientific software that is almost daily produced, usually developed in the form of scripts / small programs and non-necessarily following strong software engineering practices, likely developed by non-professional computer scientists
Service Developers
Software that is produced, published, and managed according the FAIR principles EOSC is expected to deliver
Managers
Service that includes all the functions exploited to deliver, monitor, and orchestrate the EOSC system
Policies and Procedures defined to govern the EOSC system
SLA used to define the level of service expected from the service provider
Service Providers
Scientific service that is made accessible according to the policies and SLA EOSC is expected to deliver
Infrastructure Providers
Computational and storage resources that are made accessible according to the policies and SLA EOSC is expected to deliver

13. Questions and discussions
The European Open Science Cloud for Research pilot project is funded by the European Commission, DG Research & Innovation under contract no

14. Open Discussion and Questions
Class of users are identified according to the EOSC vision and the expected emergent behaviour.
Do you perceive the need to further specialize those classes?
Scientists is the class of users including those that have to be guided towards and Open Science journey.
Do you perceive the need to specialize this class and partition the collection of services required to support their needs?
Developer Scientists is the class of users that may exploit the EOSC system to enhance their research activity significantly.
Do you perceive the need to add additional class of services to support their needs?

15. Open Discussion and Questions
Class of users are characterised by different management services
Do you perceive the need to further specialize that class of services?
The same class of Management services may require specialization according to the class of users
Do you endorse this approach?
The same class of Management services may be operated by different stakeholders while serving different class of users
