Abstract

Since the end of the nineties, Dutch census publications have been digitized and made available for digital processing. New analyses of the data were presented in some fruitful conferences in the first decade of this century. In addition to the census publications, a mass of detailed census data was found in dossiers and so-called “transparencies” in the archive of Statistics Netherlands. Most of that material was scanned into digital images, awaiting further content conversion into numeric data. In the present article, the authors describe the process of digitizing the detailed tables of the Dutch Population and Occupational Censuses held in 1947, which is the first set of detailed census data that is made available in a digitally processible form. They give an example of historical analyses made possible by this dataset. Moreover, they take these census data as an example of preparing and publishing a large dataset. Experiences and lessons learned in the process lead to ample opportunities for further analysis of the data and for efficient ways to accomplish the content conversion of the many remaining images of census data.

The Dutch Historical Censuses (1795–1971) contain statistics that describe almost two centuries of History in the Netherlands. These censuses were conducted once every 10 years (with some exceptions) from 1795 to 1971. Researchers have used its wealth of demographic, occupational, and housing information to answer fundamental questions in social economic history. However, accessing these data has traditionally been a time consuming and knowledge intensive task. In this paper, we describe the outcomes of the cedar project, which make access to the digitized assets of the Dutch Historical Censuses easier, faster, and more reliable. This is achieved by using the data publishing paradigm of Linked Data from the Semantic Web. We use a digitized sample of 2,288 census tables to produce a linked dataset of more than 6.8 million statistical observations. The dataset is modeled using the rdf Data Cube, Open Annotation, and prov vocabularies. The contributions of representing this dataset as Linked Data are: (1) a uniform database interface for efficient querying of census data; (2) a standardized and reproducible data harmonization workflow; and (3) an augmentation of the dataset through richer connections to related resources on the Web.

Master of the Minuscule
In Antoni van Leeuwenhoek, Master of the Minuscule, the Father of Microbiology is presented in the context of his time, relationships and the Dutch Golden Age. Although he lacked an academic education, he dedicated his life to investigating the microscopic world using handmade, single-lensed microscopes and magnifiers. An expert observer, he planned experiments and designed equipment to test his theories. His pioneering discoveries included blood cells, protozoa, bacteria and spermatozoa, and resulted in an international reputation among the scientific and upper classes of 17th and 18th century Europe, aided by his Fellowship of the Royal Society of London.

This lavishly illustrated biography sets his legacy of scientific achievements against the ideas and reactions of his fellow scientists and other contemporaries.
