The civil records provide a wealth of information on persons. By linking these persons, we can create pedigrees to study inequality in numerous domains: social, economic, demographic, health. Burgerlinker's features are: - extremely fast and scalable matching procedure (using Levenshtein automaton and HDT); - considers all first names of the individuals with multiple first names in order to find a candidate match; - blocking is not required (i.e. all candidate records can be considered for matching, with no restrictions on their registration date or location, and no requirements on blocking parts of their individual names); - detected links contains detailed provenance metadata, and can be saved in different formats (CSV and RDF are covered in the current version); allows family and life course reconstruction (by computing the transitive closure over all detected links); - open software
