This document summarizes several Linked Data research projects conducted by researchers at the Universidad Politécnica de Madrid. It describes initiatives to publish geospatial, transportation, cultural heritage, and meteorological data as Linked Data. These include the GeoLinkedData project, the El Viajero project about travel experiences, a collaboration with the Spanish National Library to publish its collection as Linked Data, and a project with the Spanish Meteorological Agency to publish weather station data. The researchers are involved in several W3C groups and the document outlines next steps to publish additional data from new domains.
