    dct:description "This knowledge graph was made for metadata of Statistics Netherlands (CBS) microdata (the data from individuals, companies or street level). It was a project for Knowledge Graph Course 2020 at Maastricht University. The goal of this project is to convert the descriptions of all CBS microdata sets into one knowledge graph with high-quality and comprehensive metadata so that the researchers can easily query the metadata, explore the relations among multiple datasets, and find the needed variables.";
