Currently, eTLDs for .kr contains one bogus entry while it does not have a bunch of eTLDs in the form of 'foo.kr' where 'foo' is the name of a province or metropolitan city. The bogus entry is '한글.kr'. The diagram at http://domain.nida.or.kr/eng/structure.jsp was misinterpreted (it's understandable because apparently that was interpreted by someone who can't read Korean).

Yes, you're right. I can't read Korean. But I know that 한글 means 'Hangul'. I know about the regional eTLD's like seoul.kr that need to be added. But I was under the impression that you could also register under 한글.kr. Do I have to read this as "any Hangul word can be registered as second level, other words must be third level". That's what I understand from the current version of http://en.wikipedia.org/wiki/.kr , which is different from what it was half a year ago.

Yes, '한글.kr' was just given as an example. Any Korean words (written in Hangul) can be registered at the second level. Some examples : http://청와대.kr http://정통부.kr http://과학기술부.kr There's no point of putting every Hangul domains under '한글.kr' :-) It's like requiring all Chinese domain names to go under '漢字.cn'. And, there's even an this statement at nida.or.kr :-) Domain names include Hangeul can be registered directly under .kr.

will be fixed in bug 403655 Note : the fix was to remove 한글.kr as an eTLD
