Open Data Commons, an OKF affiliated project, has now released v1.0 of the Open Database License (ODbL) after 6 months of consultation. The Open Database License (ODbL) is an open share-alike license for data and databases.
This license, the first of its kind, is a major step forward for open data as there are few license currently available which are appropriate to data and databases and none which provide for share-alike (existing share-alike licenses such as the GPL, GFDL and CC By-SA are all unsuitable for data).
This work has been led by an OKF Board Member, Jordan Hatcher, and has benefited over the last 6 months of consultation from extensive comments and feedback from the open data community, especially those in the Open Street Map project.
