EOSC Onboarding Strategy GroupCatalogue Operator Representatives for Community Catalogue from the INFRAEOSC-04-2018 (thematic projects), INFRAEOSC-05-2018-2019 (regional projects), and INFRAEOSC-07-2020 (horizontal projects) to ensure implementation/alignment of onboarding of Community catalogues; representatives of the EOSC Portal Onboarding Team (EPOT); operations and maintainer of the EOSC Profiles to ensure implementation according to decisions made within the E-OSG are considered by the EOSC Provider’s Portal developers. Other Provider Representatives interested in onboarding resources to the EOSC Resource Catalogue and EOSC Marketplace.
EOSC MarketplaceA web-based interface to search, discover, access, order and use the resources available through the EOSC Exchange, exploiting a range of filtering options, leveraging the relationships available through the Interoperability Framework, and taking advantage of integrations with EOSC Core Services and among other compatible services in the EOSC Exchange.
EOSC PartnershipA Co-programmed European Partnership between the EOSC Association and European Commission to implement EOSC under Horizon Europe. The partnership is governed by the tripartite EOSC Partnership Board consisting of representatives from the EOSC Association, EOSC Steering Board, and European Commission. The European Commission will fund €490 million in project and procurement calls in the Work Programmes for EOSC under Horizon Europe. The EOSC Association will collectively via its members contribute in-kind activities to EOSC totalling at least €500 million for the duration of Horizon Europe.
EOSC PlatformThe EOSC Platform delivers the EOSC Core and EOSC Federation services as an integrated operational environment that enables EOSC research communities to take advantage of this suite of services. Exploiting EOSC Platform capabilities, research communities can add value to their own services in the Exchange and make them more useful and attractive to a wider range of science users. Furthermore, the EOSC Platform, with its extensible architecture, facilitates the addition of new capabilities (Core or Exchange - e.g. horizontal services such as the data transfer) to satisfy emerging user’s requirements. The EOSC Platform currently consists of services such as the comprehensive Resource Catalogues, the Marketplace, the EOSC Infrastructure Proxy for the EOSC Core services, the EOSC AAI Federation, the Helpdesk, the Monitoring, the Accounting, the Order Management, the Execution Framework and the EOSC Interoperability Framework registry.
EOSC PortalGateway to research-enabling resources including research publications, data, software, and value-added services to support their research. Includes the EOSC Marketplace as well as Knowledge Hub, EOSC Observatory and other resources.
EOSC ProfileMetadata schema for the description of services, research products or other research artefacts that their providers choose to share with the EOSC user community through the EOSC Exchange, as well as for describing the organisations offering to provide these resources to EOSC. EOSC Profiles are specified by the EOSC Profile Interoperability Guideline, which defines the entities for which Profiles have been defined and their logical relationships as part of a larger data model.
EOSC Service Catalogue

EOSC Interoperability GuidelineVersion-controlled document that describes standards to enable interoperability and explain how Providers can make their resources compatible with them. They outline the high-level protocols (such as REST) and low-level protocols (such as OAI-PMH), data models (e.g. DCAT model), and schemas (e.g. DCAT JSON schema) that need to be implemented or customized to ensure compatibility with each guideline. Guidelines specify the essential technical requirements and configurations that providers should follow in order to make their services compatible with the interoperability guidelines. EOSC Interoperability Guidelines pass a validation process, after which they are onboarded (registered) into the EOSC IF registry.
EOSC Core Interoperability GuidelineEOSC Interoperability guideline to enable compatibility with specific EOSC Core services, including EOSC monitoring, EOSC accounting, and EOSC helpdesk.
EOSC ExchangeThe collection of resources and organisations onboarded to the EOSC Platform, visible in the EOSC Resource Catalogue and EOSC Marketplace, and findable accessible and usable by EOSC Users.
EOSC Exchange Interoperability GuidelineEOSC-Exchange Interoperability Guidelines facilitate interoperation of services and resources within thematic areas. As such they are defined, proposed, and maintained by EOSC providers. Specifically, horizontal Interoperability Guidelines facilitate interoperation of services and resources across communities and infrastructures, and can communicate the interoperability capabilities and boundaries of frameworks utilised by communities.
EOSC-Interoperability FrameworkThe collection of EOSC Interoperability Guidelines onboarded to the EOSC Platform, visible in the EOSC IF Registry, which can be used to enable interoperability between individual EOSC Resources and EOSC Core services as well as interoperability between EOSC Resources (e.g. enabling data transfer, orchestration, etc.). The Framework includes the governance processes for reviewing, approving and accepting new Interoperability Guidelines into the IF Registry.
