“Data is the new gold” or “data is the new oil”. Probably most people have come across one of these expressions in the past years. Which is not a surprise as more data has been generated in the past 2 years than in the history of mankind . And data and analytics are changing the way companies make decisions creating a new world of opportunities. Open data, although not a new phenomenon, recently gets a lot of attention from governmental organizations as well as private companies. Open data is the idea that certain data, such as governmental data, should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control. Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a tolerable elapsed time . Big data is often defined in terms of the following three dimensions: volume (amount of data), velocity (speed of data in and out), and variety (range of data types and sources). Not volume, but variety is the most challenging aspect nowadays, according to a Gartner survey. Linked Data describes a method of publishing structured data so that it can be interlinked and becomes more useful, tackling the variety dimension of big data. Linked Open Data (LOD) is a practical way (by defining a set of standards and guidelines) to contribute to the Semantic Web. Semantic means "learning about the meaning”. The semantic web can be defined as a web of connections between information which allows new insights to arise. Information published as Linked Open Data makes it easier to reuse that data, as it includes many references to other sources of knowledge which makes the access to the information more easy.

We hope that this roadmap inspires you to start working and experimenting with linked data, and that this roadmaps helps you in setting the first steps. We are open for suggestions about improving this roadmap, and finally if you need help you can either try the Platform Linked Data the Netherlands community, or contact us directly.
