The language code "no" is the metacode for Norwegian, and nowiki was in the beginning used for both Norwegian Bokmål, Riksmål and Nynorsk. The later split of and made nnwiki, but nowiki continued as before. After a while all Nynorsk content was migrated. Now nowiki has content in Bokmål and Riksmål, first one is official in Norway and the later is an unofficial variant. After the last additions to Bokmål there are very few forms that are only legal n Riksmål, so for all practical purposes nowiki has become a pure Bokmål wiki.
I think all content in Wikidata should use either "nn" or "nb", and all existing content with "no" as language code should be folded into "nb". It would be nice if "no" could be used as an alias for "nb", as this is de facto situation now, but it is probably not necessary and could create a discussion with the Nynorsk community. The site code should be "nowiki" as long as the community does not ask for a change. jeblad On 8/6/13, Markus Krötzsch <mar...@semantic-mediawiki.org> wrote: > Hi Purodha, > > thanks for the helpful hints.
