For the user, a graphical representation of the canton is provided which holds additional information (e.g. population, number of music festivals). This information forms the basis for further navigation. The additional data is gathered via smart linkage of different open data sources. | For the user, a graphical representation of the canton is provided which holds additional information (e.g. population, number of music festivals).

To create an added value, different information from various data sources must be linked together. Many data sources implement the RDF format to describe their meta data. That's why we're going to use as much RDF data sources as possible. | To create an added value, different information from various data sources must be linked together.

Some of the main difficulty in the beginning is the transformation of existing (meta) data into the RDF language. We started with an excel file and used Google Refine and its RDF extension to transform those raw, messy data. | Some of the main difficulty in the beginning is the transformation of existing (meta) data into the RDF language.
