This report is a milestone of the FAIRsFAIR project. The document describes the work that is being done to improve re3data registry to enable researchers identify FAIR enabling repositories to find relevant datasets or deposit their research data. We are taking input from multiple efforts such as CoreTrustSeal plus FAIR alignment of repository practice, FAIR data repositories features and FAIR Object Assessment within FAIRsFAIR to identify specific properties within re3data schema that can be used or extended to capture criteria for FAIR enabling repositories. In parallel, we are also developing APIs to provide access to the re3data metadata and a search application to discover FAIR enabling repositories. The outcome of this is an improved description of repositories, hence enhanced metadata. This work will set the foundation for streamlining assessment and certification through improved organizational and data collection metadata.
