For our July 11th lecture... Do I need to license my open data? There are licenses for data just like there Creative Commons for content. What are the open data licenses and how should you use them? We will be giving an introduction to open data licenses. A lively discussion will follow the short program.

No License Option for Open Data
● If no license is mentioned (even public domain) then
like most other websites it becomes a case for the
courts.
● Most curated content is not specifically licensed and
this is why copyright (all rights reserved)
automatically applies to creative works.
● This means without a license then it could be
assumed that what is meant to be open data, in fact
isn’t.

Creative Commons for Open Data
Only CC-BY and CC-BY-SA can be used for Open Data.
The best Open Data license remains CC zero. Very hard to enforce all others.

Open Data Commons
● Distinguish Between the “Database” and its
“Contents”?
– They may have separate rights
– For example, consider a database of photographs. Here
there are the rights in the database and quite separate
individual copyrights in the photographs.
– Or consider the example of Freebase which contains
textual material and images from Wikipedia as well as user
contributed material. While Freebase controls the database
the individual items of contents need to have their own
separate license
