Scientific data must be open. Everyone should be able to check them, reuse them. More over they should be always available in a easy way.
That’s why the panthon principle have been launched:
Science is based on building on, reusing and openly criticising the published body of scientific knowledge.
For science to effectively function, and for society to reap the full benefits from scientific endeavours, it is crucial that science data be made open.
Data is not code and data is not artistic work. This means all the classic licence that we love and we always use like the GNU Public Licence or the Creative Commons (except CCZero) are not good enough for data. Data does not belong to anybody in particular but belongs to everybody. That’s why it’s really important to use the right license. A list is available here .
