The Epigraphic corpus of Mediaeval and Early Modern inscriptions in Slovenia collects carefully made transcriptions of Latin inscriptions that are found or have been discovered on the territory of Slovenian coastal towns, focused on Koper and Piran. The 51 collected inscriptions date from 1222 to the middle of the 17th century. The purpose of the corpus is to provide a methodological basis for the processing of inscriptions found or discovered in the Slovenian ethnic territory. The corpus brings together inscriptions that are either still located in their primary context or have been moved or even destroyed and are therefore accessible only in transcriptions. The material was collected through field research, i.e. the recording and documentation of inscriptions in situ. The corpus transcriptions have been carefully annotated, with the ligatures and abbreviations marked-up and expanded, and the texts translated into Slovenian. Various metadata (in Slovenian) have also been collected and included in the descriptions. The corpus is encoded in TEI XML, using the elements for manuscript descriptions for inscription metadata.
