+## Dataset summary
+
+Dataset consisting of eight data fields taken from the Diplomatarium Fennicum -database. 
+
+Diplomatarium Fennicum -database (df.narc.fi) contains medieval charters and text excerpts conserning Finland and Finns, 
+and is published and maintained by the National Archives of Finland.
+
+The data fields selected are central to identifying, categorizing and analyzing the texts. 
+The dataset represents only very minimally the whole database; the selected data have been cleaned and combined,

+in the fields of digital humanities, data analytics and linguistics.
