Introduction to the guidelines for repositories and registries on exposing repository trustworthiness status and FAIR data assessments outcomes

To reach an intended aim of the European Open Science Cloud (EOSC) to be a research data environment populated with digital objects that present a range of desirable characteristics, including FAIRness, a complex partnerships of actors and agents, performing activities and delivering services, are required to be involved in creating processes and activities across the research (meta)data lifecycle and ecosystem, from the initial conception of a research goal, through data creation and collection and deposit in a repository, to eventual reuse. The ability to cooperate, interoperate, and deliver services to end users depends on mutual trust between service providers and digital object creators, depositors, users, and funders. 

The intention of the guidelines, introduced here, is to increase the transparency of information about metadata and data services and the digital objects they hold by exposing it in ways that enable humans and machines to harvest, exchange, and use the information. Thus providing a foundation for interoperability, establishing trustworthiness and allowing the (meta)data service to improve the current state of connections between the services, including registries, and the information they can exchange at the organisational and the digital object level.
