Historians have been working with historical person data for decades. The increase in computing power has made it possible to reconstruct populations of an ever-increasing size. To move beyond local and regional reconstructions of historical populations, data standardisation and specialised software is required. With Persons in Context (PiCo), the Dutch Center for Family History (CBG) has released a model to standardise historical person data. PiCo supports a move from XML to RDF and has the necessary quality and support from archivists and scholars to develop into a national, and perhaps even international, standard. Ideally, implementing PiCo will not only make transcribed historical data more FAIR, but will also improve the quality of software that processes historical person data. This paper explores the implications of applying PiCo to the LINKS pipeline for reconstructing life courses and family relations in the Netherlands as part of the CLARIAH WP4 project. In our presentation we will discuss the practical implications of introducing the model into an existing pipeline and explore the possibilities for extending our pipeline to other historical data sources and countries.
