License and Requirements
ODP data was previously made available under the terms of the Open Directory License, which required a specific ODP attribution table on every Web page that uses the data.
The Open Directory License also included a requirement that users of the data continually check the ODP site for updates and discontinue use and distribution of the data or works derived from the data once an update occurs. This restriction prompted the Free Software Foundation to refer to the Open Directory License as a non-free documentation license, citing the right to redistribute a given version not being permanent and the requirement to check for changes to the license.
In 2011, the ODP silently changed its license to a Creative Commons Attribution license.
