ABSTRACT
This chapter reviews three in-use systems for publishing and studying military history on the Semantic Web, namely, WarSampo, WarVictimSampo 1914–1922, and WarMemoirSampo. Targeting Digital Humanities researchers, application developers, and the general public, these systems include a Linked Open Data (LOD) service with a live SPARQL endpoint that can be used with modest programming skills, and a ready-to-use semantic portal on top of it. Lessons learned in developing these systems are discussed based on the so-called Sampo Model, which is a set of principles developed in the process of creating and publishing Knowledge Graphs (KG) as LOD services with semantic portal User Interfaces (UI). The UIs support semantic faceted search, data browsing, and exploration, as well as seamlessly integrated tools for data analyses.
