OPEN LINKED DATA : HOW TO CONVERT AND PUBLISH STRUCTURED DATA AND DEMONSTRATIONS OF POSSIBLE USES

Abstract: The goal with this project was to convert open structured data, e.g. csv-files, to Linked Open Data and to demonstrate possible uses of such data. The project was also supposed to inspire and lay a foundation for future work in the area. The conversion was done using the D2RQ platform, and the chosen dataset contains air quality measurements from Umeå Municipality. The resulting data was then published on the internet with D2R server. For demonstration purposes two tasks were done. A visualization of the converted data was published on the web, together with traffic and weather data. Secondly a physical city model was built of carton with eight photodiodes, a Raspberry Pi and visualized with a local webserver. The goals for the project were fulfilled and it has also inspired Knowit to continue with commercial projects in the area of Linked Open Data. Future effort should be put in converting more data to Linked Open Data and to create full scale sensor networks in a city.
