This is a LegalHack@OKCon 2013 challenge.

The ongoing challenge in the Open Data community is to understand where restrictions on data exist, and to create grounds for public appeal to the data owners for changes to the terms of use. While the discussion is taken to a high political level on certain highly sought-after data sets, there are many relevant and useful sources of information which may even be published online and accessible, yet are still not open due to their legal definition (or lack thereof!).

The only option for most people is to go through a Freedom of Information request process, but they may not be willing to go “all the way” and give up - an Open This Data! button or even just a simple hashtag could organize a wider community. As Opendata.ch president André Golliez recently said in an interview “the legal situation (of open data) is one of the largest medium-term problems. There are many constraints, such as on how data can be published. Everybody is anchored in law. Only data on which no restrictions are attached, should be open.”

Let's give people a quick and easy way to express their wish that the data be free! Here are some possible hackday goals:

• Start crowdsourcing a database of not-so-open data
• Develop an easy way of sharing dataset restrictions, like a browser bookmarklet button
• Seed the database and create an early visualization, a preview of the “not-so-open-data map”
