The workshop took place on February 23, 2015 in DELab. In the exercise, we got to know the TEI elements used for the detailed description of places, the methods of linking between such defined places and references to them in the text, and then we extracted this data using XSLT to JSON format, which in turn served as a data source for the javascript leaflet library. In this way, we went through a complete path from preparing data to its visualization in the form of a map embedded in a website. http://tei.oucs.ox.ac.uk/Talks/2015-02-warsaw/
