<hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt">Our research project offers various methods of modelling and visualization of a large scaled database and metadata, considered in a FAIR way with open access, open data and open code. Firstly, we developed a knowledge graph using a semantic data model, which offers a data-centred approach for the Congregation of the Council in global context in the early modern period. Secondly, we created open access research tools for contextualizing historical data, including unclear, uncertain and incomplete information, into a big picture of global legal history, providing a graphic and accessible visualization of the data. For the time being, our data covers the period from 1564 to 1680 and are concentrated on the SCC, but data collection will continue for the later periods and our methods can be profitably applied also to other bodies of the Roman Curia. Therefore, our research and the tools we are developing can be of great importance for the understanding of the administration of justice in the Western World from the Late Middle Ages to Contemporary period.</hi>
