Invited Talk: Re-using the ParliamentSampo framework and Sampo-UI

This presentation shows how the domain-specific “Sampo framework”, here ParliamentSampo for parliamentary speeches and prosopography [1], based on the domain-agnostic Sampo model [2] and Sampo-UI interface model [3-4], can be adapted to new application cases. As an example, our focus here is to show how to publish as a FAIR Linked Open Data (LOD) service the assembly minutes of the League of Nations [5], the predecessor of the United Nations (UN), and to publish next the General Assembly minutes of the UN. As an application on top of the LOD service, the portal League of Nations (1920-1946) Sampo [5] was published on the Web in March 2026. It can be used to answer questions, such as: What have the representatives of Japan talked about? How did the territorial focus of the League of Nations (LoN) shift in time? In what roles and capacity did Fridtjof Nansen, the Polar explorer, participate in LoN meetings?
