This presentation was given as part of the EOSC Stakeholders Forum Scientific Community Workshop which gives the opportunity to prospective consumers and providers - from both the public and commercial sectors - to discuss needs and opportunities that should drive the definition of the EOSC service portfolio roadmap. This workshop aims to answer the following: - What prospective needs and priorities do scientific communities have as consumers of the EOSC? - How should EOSC facilitate the sharing of data, scientific outputs and services across national and organisational borders? The workshop starts with a presentation of today’s state of play in federating resources and services to enable multi-disciplinary science and transnational access; it featured invited talks from representatives of digital infrastructures, research projects and communities and the long-tail of science. The workshop also involved representatives from both public and commercial organisations in their role as a service provider and service consumer. The workshop participants also took the opportunity to define a list of recommendations giving direction to the development and provisioning of the EOSC portfolio.

● A single scientific repository is of limited value
● Real benefits come from ability to exchange data
within a network
● Current technology for exchanging data across
repositories (OAI-PMH) more than 15 years old
○ Scalability
○ Implementations inconsistency
○ Metadata synchronisation only

● Assess how scientific resources can be effectively,
regularly and reliably exchanged across systems using
the ResourceSync protocol.
● Conduct a set of experiments/benchmarks comparing
OAI-PMH with ResourceSync along a set of dimensions,
scenarios and implementation setups.
○ different repository platforms, over 1k repository
systems, variety of configurations and scenarios
○ quantitative benchmark and case for adoption of
ResourceSync.

● Guidelines for adoption (EOSC/domain specialists)
● Knowledge and skills gap between between technologists
who implement repositories and those who manage it

● Tested approach widely applicable and with clear benefits
over currently used technology.
● Recommend ResourceSync as a default data and
metadata exchange protocol for all repositories operating
within EOSC.
● Need a communication channel to work with WP6
Interoperability (and others) to communicate results and
decide next steps.
