This report presents a first iteration of guidelines that will help to expose relevant information at the organisational and object level to facilitate discovery, provide context, and support interoperability between repositories, registries, and other related stakeholders. By improving the flow of information between stakeholders more trusted perceptions and relationships about the services provided and objects held or referred to by them can be fostered. The guidelines will focus on exposing information about characteristics (e.g. repository name, contact information), information that can inform a sense or status of trust (e.g. a certificate, preservation policy), and information relating to FAIR assessment (e.g. assessment results, tool(s) used). Supporting this first list of guidelines, the rationale, methodology, scope, and added value scenarios are all discussed to place the creation of the guidelines in their full context. The report also covers the plans around the further development of the guidelines and the prototype that will implement them, to offer a full picture of the envisioned line of work. The main aim of this report is to continue to invite community-input on the guidelines presented, as it is of great importance that the guidelines are relevant to the community that would implement them. Continuous opportunity for providing feedback on the document (presented on the FAIR-IMPACT website), as well as targeted outreach activities from the project will result in future iterations of the guidelines, and reports on the prototype explorations will depict a practical implementation of the model.
