Now it's official: the Norwegian government has mandated the use of open document formats from January 1st, 2009. There are three formats that have been mandated for all documentation between authorities, users and partners. HTML for all public information on the Web, PDF for all documents where layout needs to be preserved and ODF for all documents that the recipient is supposed to be able to edit. Documents may also be published in other formats, but they must always be available in either ODF or PDF."
