weighed by the benefits of proper reuse that facilitate scholarly research and public discovery.� 3. Resources. As much as we would like to think it is, open data is not free to produce, and resources are often scarce in these institutions. So if the data is free, who pays for it? As in most other businesses, going digital requires a new way of thinking about making money. The music and film industry showed that people no longer pay huge amounts of money for content if its free equivalent is also easy accessible. Institutions therefore have to make the shift from being a provider of content to becoming a provider of services. This means participating with the audience, meeting their needs and finding new ways to engage with them. At the same time, open data can also save the institution a lot of money. Think about the possibilities of the web for crowdsourcing. Thousands of individuals can do millions of micro tasks that would take institutions forever. Combined with the open source tools that are now available to facilitate this makes it a tremendous resource. The issues mentioned here are tough, but can and should be solved—and now is the time to do it. Fortunately, there are many initiatives, organisations and projects that help institutions to overcome these problems, search for the appropriate solutions and implement them. The first step for institutions is to think about opening up their data, start experimenting with it and learn from each other. In this way, we can reach the goal of creating a better world where all knowledge is freely accessible to anybody, anytime, anywhere. After the Open Knowledge Festival, I am more convinced than ever that we are heading in the right direction. During the Open Knowledge Festival, we organised the Open Cultural Heritage stream. When we started doing this, we got in touch with a couple of great people who helped us to build this topic stream to make it one of the biggest in the festival. The OpenGLAM initiative, which is part of the Open Knowledge Foundation, teamed up with groups such as Wikimedia, Creative Commons, Open Culture Data and many more during the festival. We shared experiences and discussed the most pressing current issues during the ‘Building the Cultural 13
