In November 2018 at SWIB18 conference a breakout session "" took place. Participants wished to find a place to record the results and follow up on the discussion. This wiki page is meant to serve this purpose.
It is hosted by the German DINI-AG Competence Centre Interoperable Metadata (KIM). Further exchange of any parties interested could be initiated through comments on this page or through the mailing list of KIM's Working Group "Identifiers" (registration, public archive).
