The article is a summary of the work that is being done at the Project Medieval Iberia through Pelagios Commons, led by Gimena del Rio. The project has two main objectives: to contribute to the extension of Pelagios by adding Mediaeval Iberian placenames and to develop a framework for the knowledge extraction of Mediaeval Iberian placenames in reliable and verifiable digital sources in Spanish.Mediaeval Iberian placenames are not easy to identify and locate. Not only is there no Spanish/Iberian gazetteer with which to identify geographical places from such literary sources or map them to current geography; at present there is no system in place to regularise the names used in the surviving texts, which contain many phonetic and linguistic variations. It is also the case that many of the places which appear in the literary texts were either invented by their authors or were named in different ways throughout the centuries. Mediaeval Iberia is still a work in progress and will be finished by the end of 2017.
