Sharing is our way of life. Our existence and civilization is founded upon the principles of collaboration and sharing of resources and knowledge. In cyberspace we share images, cake recipes, opinions, and some even share things that belong to others. But in the field of education things are a little different.

Because knowledge is power, money and prestige, and here there are too few incentives to motivate extensive sharing. In addition, sharing knowledge in cyberspace is not straightforward: Digital knowledge sharing assumes that we agree on the constituents and building blocks of knowledge, and how these are represented and distributed.

NDLA is a national project with high ambitions on behalf of the sharing culture: Creative commons, open source and lifelong access for the public are some keywords. So high have the ambitions been that NDLA these days are launching a semantic model where topic maps and RDF melt together.
