The aim of STREAM is to develop a research infrastructure for early modern Flanders and Brabant (c.1550-1800). STREAM is designed to protect, utilize and make accessible a multitude of historical data for diverse research applications and for the public at large. STREAM compiles a range of data from a diversity of sources and provides us with a geographically comprehensive and long-run quantitative account of early modern Flemish society. It contains key data regarding territory, demography, transport, agriculture, industry, trade, labour and social structure. The infrastructure rests upon a geographical information system and a database storing the original and harmonized statistical data at the local level. This enables scholars to easily consult historical data and to implement historical reconstruction maps for their own research.
