[urn] Some initial thoughts on draft-ietf-urnbis-rfc3188bis-nbn-urn-02

[Bengt Neiss <[e-mail]>]

Hello all..

Just some initial thoughts on the new text...


1.       In chapter 4.2. "Encoding Considerations...." the expressions "primary prefix" as well as "secondary prefix" are introduced. I think we need to rephrase this since "prefix" is the expression used otherwise in text. As it is written now there is a sentence that states that the NSS consists of three parts and then there is a list with four "parts"... (might be better as "primary part of prefix", " secondary part of prefix" which occurs in occurs in other places text). I think it should be similar to the text in "Declaration of syntactic structure..." on page 12 - 13.


2.       The sentence "Future NBN implementations SHOULD make the NBN string case insensitive as well". Is this a relevant statement?
Since it seems to be that the nbn_string may be case-sensitive depending on syntax applied locally (ie. already implemented) and URN:s are persistent the case-sensitivity of the nbn_string must always be taken into consideration...



3.       I think there is a need to work further on defining restrictions or evaluate the consequences of the current text. Will make a new post on some issues  later..
