The [original dataset](https://dataverse.bsc.es/dataset.xhtml?persistentId=perma:BSC/0VB0MC) consists of 100 images (digitized medieval charters written on parchment) and their associated 100 PageXML files. The dataset is split into train (60 documents), validation (20 documents), and test (20 documents). This derived dataset is comprised of 3,369 lines, each consisting of the polygon-shaped image of the line, its transcription, and associated metadata.
