The Emilia-Romagna Region has implemented an innovative solution – Open Geo Data – that exposes data and metadata managed by its SDI as Open Data, with particular attention to the RDF/XML, and then as Linked Open Data. The software application realized, called GetLOD, derives from a collaborative effort between Planetek Italia and Sinergis, two italian SME operating in the geospatial market, who partnered with RER to successfully implement an innovative solutions by adding value to existing SDI technologies. The SDI of the Emilia-Romagna Region, Italy is based upon a metadata catalogue and a repository manager that organizes the access to geographical data, and it has been completed by applications and services oriented at different levels of government, that are now accessible through a single interface, the regional GeoPortal http://geoportale.regione.emilia-romagna.it. The GetLOD application allows to transform (open) data and web mapping (open) services into Linked Open Data, compliant to the "five star" classification given by Tim Berners-Lee. The data and metadata extraction services are based on the use of the standards defined by the OGC for Geographic webservices. The data suitable for publication in the form of Linked Open Data are extracted in RDF format by leveraging the Web Feature Services (WFS) provided by Emilia Romagna SDI. Extraction of geographic metadata in RDF format is carried out using the standard OGC Catalogue Service for the Web (CS-W). The dynamic generation of RDF based on open services ensures the continuous alignment with the regional Open Data Portal. Finally, the solution is entirely based on free open source software to ensure the reusability of the system. GetLOD therefore can be integrated into any cartographic Geoportal or SDI (Spatial Data Infrastructure) based on OGC standards. The geographic open data can be exploited both in RDF and in other interchange formats (for example in Shape File format).
