The attestations belong to the database Diccionario del Español Medieval electrónico (DEMel) and consist of word forms that were excerpted from medieval Spanish texts. The aim is to link the attestations from the database with their source texts by annotation. As some of the information, required for the tagging, is derived from digitized handwritten paper slips, none of the existing tools is suitable.
