Document: draft-hakala-urn-nbn-rfc3188bis-00 Reviewer: Robert Sparks Review Date: 2018-05-01 IETF LC End Date: 2018-05-21 IESG Telechat date: Not scheduled for a telechat Summary: Almost ready for publication as an Information RFC but with issues that need to be addressed before publication. Why is there no shepherd's writeup? It would be good to explicitly let the community know why this is proceeding as an individual draft. Issues: The document uses 2119 in some inappropriate ways. It's fine to use 2119 terms when defining how to construct NBN URNs. It's not ok to use them in places like "the national library MUST", and "A national library ... SHOULD specify ... a policy" and "libraries MUST agree". Please find a way to say that if a national library wants things to work, they will or should do these things. While I agree with the values expressed, it seems odd for the URN registration to try to put constraints on fees that a national library might collect (especially using a 2119 SHOULD). Nits/editorial comments: The section calling out this draft replaces draft-ietf-urnbis-rfc3188bis-nbn-urn should be removed (its enough to add RFC editor instructions to the draft or to the ballot writeup). "identifiers identifiers" occurs in the second paragraph on page 4. The ABNF in "Declaration of syntactic structure of NSS part" needs to be reformatted to meet the RFC constraints on line length. Consider "physical" instead of "hand-held" in the first paragraph of 3.1. A national library may choose to assign an NBN to something too large to pick up.
