Last week we had a meeting about building a set of Public Domain Calculators for countries across Europe (which we blogged about earlier this month). The public domain calculators will help to determine whether or not a given work is in copyright in a given jurisdiction.
We started out by reviewing existing work on the calculators. We then put together first drafts of diagrams representing copyright law in the Netherlands and the United Kingdom. We also started work on a tutorial to help others getting started in building public domain flow diagrams for other countries. Finally we shot some footage for a micro-short film introducing the project – so watch this space!

Documentation for the event is now available, including:
- Draft flow diagram for the United Kingdom (in PDF)
- Draft flow diagram for the Netherlands (in PDF)
- Source files for flow diagrams at the Internet Archive
- Main meeting page on wiki
- Draft questions for legal experts to help build calculators
- Photos:

The Public Domain Calculators meeting was organised by the Open Knowledge Foundation and the Centre for Intellectual Property and Information Law at the University of Cambridge as part of Communia, the European policy network on the digital public domain.
