... We can now announce a new license to the Open
Data Commons family, the ODC Attribution License (ODC-BY) license. This
is a database specific license requiring attribution for databases.
This makes ODC-BY similar to the Creative Commons Attribution license,
but is built specifically for databases. As a legal tool that only
requires attribution, it complies with the Open Knowledge Definition, the
Open Knowledge Foundation’s standard
around defining the rights behind what something means to be “open”.
