“…[2] Although this paper describes and discusses the processing of Finnish epistolary metadata (or metadata that has ended up in the Finnish archives and museums), we believe that our experiences may have wider significance. In Europe, there are several digital humanities projects that harvest well-curated metadata (detailed information about senders, recipients, dates, and places) from edited letter collections -like Europeana 1 [3], Kalliope Catalogue 2 , The Catalogus Epistularum Neerlandicarum 3 , Electronic Enlightenment 4 , ePistolarium 5 [4], SKILLNET 6 , correspSearch 7 , the Mapping the Republic of Letters project 8 , NorKorr -Norwegian Correspondences and Linked Open Data [5], and Early Modern Letters Online (EMLO) 9 [6,7,8]. Bruneau et al discuss applying Semantic Web Technologies to modelling the correspondences of French scientist Henri Poincaré and publishing on an online portal 10 [9].…”
