In the EC-funded WorldFAIR project, CODATA (the Committee on Data of the International Science Council) and RDA (the Research Data Alliance) work with a set of 11 disciplinary and cross-disciplinary case studies to advance implementation of the FAIR principles and, in particular, to improve interoperability and reusability of digital research objects, including data. Particular attention is paid to the articulation of an interoperability framework for each case study and research domain.
According to the WorldFAIR approach, outputs and modes of dissemination will significantly strengthen international cooperation in order to increase and mainstream FAIRness of data and digital objects.
One of the outputs of the WorldFAIR project was the "Cross-Domain Interoperability Framework (CDIF)", which is designed to support FAIR implementation for these projects by establishing a ‘lingua franca’ for this information, based on existing standards and technologies to support interoperability, in both human- and machine-actionable fashion. CDIF is a set of implementation recommendations, based on profiles of common, domain-neutral metadata standards which are aligned to work together to support core functions required by FAIR. Another major deliverable of the WorldFAIR project was a set of 11 policy recommendations to support a fundamental transformation of data stewardship to meet the challenges of interdisciplinary research, reproducibility and AI.
