Linking Open Data Community Effort
In order to enable people to use the data that you are publishing on the Web on a secure legal basis, you need to explicitly state which license applies to your data. If no license is specified, people cannot use your data within any serious applications.
Thus, this page collects information about
- data licenses that you can use for your data.
- best practices on how to annotate your data with licensing meta-information.
The page is part of the community project SweoIG/TaskForces/CommunityProjects/LinkingOpenData
