The Java converter tool mentioned earlier parses the MI properties file and converts it to Markdown and nanopublication RDF formats. This way, each MI is represented with its own nanopublication identified using the nsdrami namespace (). The nanopublication defines the human-readable label and assigns the MI to the fairmi:FAIR-Maturity-Indicator class from the fairme namespace ( indicator/terms/Gen2/) which is the class used by Wilkinson et al. work and thus making it interoperable with the output of that work. Also, the nanopublications are assigned a Trusty URI which is required to publish them to the nanopublications network. The Trusty URI uses a base URL from w3d.org which makes it a persistent identifier. Moreover, the NSDRA metadata generator, MI generator, and the evaluator web application Supplementary information. Supplementary material including extended tables for maturity indicators grouping by application and general endpoints.
