1 Linked Open Data From OGC Compliant Web Services: The Case of Regione Emilia - Romagna Geoportal Inspire Conference Florence 26/06/2013 Giovanni Ciardi (Regione Emilia-Romagna) Alfredo Abrescia (Planetek Italia) Stefano Pezzi (Sinergis) 01/07/2013

3 Geoportal & OpenData Portal The Geoportal represents an important part of the Open Data policy of the Region Emilia Romagna. With a strong integration with the regional Open Data portal, the Geoportal is a provider of (geo)data in favor of the portal dati.emilia-romagna.it

4 ER Geoportal The ER Geoportal allows the diffusion, the distribution and the use of geospatial data, information and geographical services both to the public and the staff of the local and national government. It is compliant to the latest regional, national (AGID, Intesa GIS ) and international (INSPIRE, OGC ) guidelines in terms of interoperability.

8 Towards Linked Open Data Data, if isolated, have little value. The value of data increases when different data sets, produced and published independently by different individuals, they can be crossed freely by third parties. The generation of dataset in RDF format (Linked Data) increases the value of the data allowing connections among themselves and with external dataset! 8

9 Towards Linked Open GEO Data Free data is not enough! In order to offer a really useful service to citizens, institutions and companies, you need to aggregate, process data and offer them as services. The creation of a "ontology network" of the Geoportal data, allows to move from one conceptual dataset to another. Ontologies are considered one of the pillars of the Semantic Web.

11 GetLOD: Open GeoData Solution GetLOD is an open and reusable solution for publishing geographic data on the Web as Linked Open Data, according to the standard RDF / XML. GetLOD thus ensures the Web publication of geospatial data as open and linkable data, starting from traditional cartographic webservices 11

12 GetLOD: Open GeoData Solution Open and reusable solution It is integrated with the Spatial Data Infrastructure thanks to the standards defined by the Open Geospatial Consortium (OGC) WFS and CS-W. It allows to publish the geographic open data both as RDF (Linked Open Data) and in other non-linkable interchange formats (Shapefile and GML) 12

13 GetLOD: Open GeoData Solution GetLOD ensures the use of data as Linked Open Data: indexing on open data search engine integration with open data portals or the Comprehensive Knowledge Archive Network (CKAN), the catalog of the free dataset and projects. 13
