While several public institutions provide its data openly, the effort required to access, integrate and query this data is too high, reducing the amount of possible dataset users. The Blended Integrated Open Data (BIOD) project has as objective to ease the access to public Open Data. It integrates and makes available more than 300Gb of data, containing billions of records from different Open Data Sets, allowing to query over them, and thus to retrieve related information from originally disconnected data sets. This paper presents the set of open data available, how to access it and how produce new compatible data to improve the existing data set.
