By now you should have a good idea what your data looks like and how copyright works in your jurisdiction. The next step is to pick one or more datasets, this can be an entire collection or a subset of a collection, to put this theory in to practice. To do this, we have developed a couple of guidelines to help you with the selection. 

If you completed the previous task you should have a list of all the data of your institution. Now we're going to divide the sets in 4 categories: Metadata, content in the Public Domain, content of which you own the copyright yourself and content to which third parties own the copyright. 

If you live in the EU there's a handy tool to determine wether a work falls in the Public Domain or not. Just go to http://www.outofcopyright.eu and follow the steps there
