Knowledge transfer is a key part of official development assistance, and many government programs revolve around conveying knowledge to the community. Using open licenses for content is an important means of making that knowledge transfer effective.
Governments often develop content, e.g. for sustainability programs, and if open licenses are used, this can be shared and collaboratively developed between them, and with other groups, for maximum impact.
Governments and open content
The US federal government has large amounts of public domain content, as under US law no work by an officer of the federal government may be copyrighted. See US federal government websites and public domain
The Queensland state government in Australia is exploring open licenses:
On behalf of the Queensland Government, the Office of Economic and Statistical Research (OESR) in Queensland Treasury is trialling the implementation of the Government Information Licensing Framework (GILF) a set of standardised licences that will make it easier for information users to understand what they can do with public sector copyright information, whether viewing, copying or making new products. --
