Hi Guy, et al., Would it still be possible to give a short presentation at the upcoming NSI conference call (Wed 12 Feb)? At OGF40 some concerns regarding the URN identifier format have come up, and after some discussions with Diederik Vandevenne (SURFsara), Ralph Koning and Miroslav Živković (both University of Amsterdam), I've came to the conclusion that at least some of the issues stem from the different uses of URNs. Basically, as identifiers in NML and as addresses in NSI. We don't have a clear solution, but I thought it may be useful to explain the distinction between identifiers and addresses to those interested, and how this may applies to NSI. Is it still acceptable if I'll send some slides Monday later at the day? Thanks!
