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.

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!

Linked Open Data… and GeoData
� 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 reuse of common ontologies allows to move from one conceptual dataset to another.
� Ontologies are considered one of the pillars of the Semantic Web.

From GetLOD…
� 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

� GetLOD thus ensures the Web publication of geospatial data as open and linkable data, starting from traditional cartographic webservices.
� It is integrated with the Spatial Data Infrastructure thanks to the standards defined by the Open Geospatial Consortium (OGC®) WFS and CS-W.
GetLOD is a solution jointly designed and developed by Planetek Italia and Sinergis during the the evolutive
developments of the Geoportal of Emilia Romagna Region.http://www.planetek.it/eng/getlod

R&D : triple stores
� Strabon - Strabon is a semantic spatiotemporal RDF store. Strabon is a full implementation of stSPARQL and the GeoSPARQL Core, Geometry extension and Geometry topology extension components.
� Parliament - A geospatial RDF store that implements the GeoSPARQL Core, Geometry extension and Geometry topology
11
GeoSPARQL Core, Geometry extension and Geometry topology extension
� uSeekM - A geospatial RDF store that implements the GeoSPARQLCore, Geometry extension and Geometry topology extension.
� Virtuoso - A semantic repository enhanced with geospatial capabilities that allows the representation of point geometries and offers vocabulary for a subset of the ISO 13249 SQL/MM standard.
� AllegroGraph - is one of the first RDF stores that provided support for geospatial data.
� Oracle Spatial and Graph- http://www.oracle.com - Starting from version 12c, Oracle provides a full implementation of GeoSPARQL.
