Publishing OTALEX-C Observatory data according to Linked Data
INSPIRE Conference 2013 Florence, 23-27 June
OTALEX-C project
• Territorial and Environmental Observatory of the cross-border region: Alentejo and Centro in Portugal and Extremadura in Spain.
• Monitoring and analysing territorial and environmental changes and pressures on both sides.
• Difficulties for having quality GI of this territory.
• Sharing information from different levels and homogeneous data through the SDI-OTALEX. 2 INSPIRE Conference 2013

Conclusions
• Main results • An ontology network related to the OTALEX-C project. • A tool (shp2RDF) for dealing with shapefiles and creating RDF. • From unstructured data to Linked Open Data • A viewer where WMS services and Linked Data are combined.
• Future work • Generating and publishing Linked Data. • Supporting the extension to GeoSPARQL. • Studding in depth multilingual issues.
