The Norwegian Government mandated the use of open document formats from January 1st, 2009.Therefore, all information on state-operated Web sites should be accessible in the open document formats HTML, PDF or ODF.

The Government's decision is as follows:

• HTML will be the primary format for publishing public information on the Internet.
• PDF (PDF 1.4 and later or PDF/A ISO 19005-1) is obligatory when there is a wish to keep a document's original appearance.
• ODF (ISO/IEC 26300) is to be used to publish documents to which the user should be able to make changes after downloading, e.g. public forms to be filled out by the user. This format is also made obligatory.
