Agenda
• About FAO• FAO Country Profiles • Contribute to the Linked Open Data (LOD)
cloud• Exploit LOD resources • Expose FAO Country Profiles data in Resource
Description Framework-in-attributes (RDFa)• Conclusions and next steps
2FAO Country Profiles
The Food and Agriculture Organization of the United Nations (FAO)
• Established in 1945• One of the major agencies of the UN system• Counts 192 member countries.• HQ is in Rome and has more than 100
decentralized offices around the world.
3FAO Country Profiles
Knowledge organization• Article 1 of FAO’s Constitution:
– “The Organization shall collect, analyse, interpret and disseminate information relating to nutrition, food and agriculture”
• FAO experts’ knowledge network:– Agronomists, foresters, fisheries and livestock specialists, nutritionists,
economists, statisticians, ICT and IM professionals.
• FAO Internet knowledge in numbers:– 2.3 million monthly visits– 3 million web pages, 100 000 documents, hundreds of DBs and
information systems
4FAO Country Profiles
FAO Country Profiles
• launched in 2002• a fast and reliable way to access country-
specific information produced by FAO from a single entry point
• Data sources: FAO, FAO-partnership and non-FAO
• Average 250,000 monthly visits
5FAO Country Profiles
FAO Country Profiles in LOD
• Contributes to the LOD cloud with a Resource Description Framework (RDF) version of FAO’s country-based reference data
• Exploits the LOD resources to provide enhanced country profiles in Food and Agriculture.
• Exposes FAO Country Profiles data in RDFa to improve search and reuse
6FAO Country Profiles
Contribute to the LOD cloud
• Embracing the W3C LOD initiatives• Releasing the FAO geopolitical ontology in
RDF format
7FAO Country Profiles
FAO geopolitical ontology
• A mechanism to describe, manage and exchange data related to geopolitical entities
• provide the most updated geopolitical information (names, codes, statistics, historical changes, and so on)
• Associated services– Module maker – Web Services
• Various use cases inside and outside FAO

10FAO Country Profiles
FAO geopolitical ontology in LOD
• RDF/XML format • 22,495 triples • 195 links to DBPedia• RDF dump
11FAO Country Profiles
Architecture to implement
12FAO Country Profiles
Demo
• http://www.fao.org/countryprofiles/geoinfo/geopolitical/resource
13FAO Country Profiles
Exploit LOD resources
• Exploring LOD’s large and interoperable information base
• Integrating appropriate LOD resources into FAO Country Profiles– Covering most of countries – Updating in regular basis– Providing RDF representation– Including interesting content in the context of
FAO Country Profiles
14FAO Country Profiles
Global Hunger Index (GHI)
• A multidimensional overview of global hunger
http://www.ifpri.org/publication/2010-global-hunger-index15FAO Country Profiles
Global Hunger Index dataset in LOD
• Modeled in a RDF data Cube multi-measure model
• Provides the GHI of about 130 countries • Identified with ISO 3166-1 alpha-2 country
code• URIs containing year and ISO 3166-1 alpha-2
country code (i.e. GHI of India in 2010 http://data.ifpri.org/rdf/ghi/2010/qb/#observation-2010-IN)
http://data.ifpri.org/rdf/ghi/
16FAO Country Profiles
GHI in FAO Country Profiles
http://www.fao.org/countryprofiles/index.asp?lang=en&ISO3=IND17FAO Country Profiles
Expose FAO Country Profiles data in RDFa
• Embedding RDF triples within FAO Country Profiles pages
• Examples:– Describing country official name in the selected
language (rdf:label)– Linking to FAO geopolitical ontology (owl:sameAs)– Mapping AGROVOC keywords (skos:closeMatch)

Conclusions
• Contributes to the LOD cloud with a RDF version of FAO’s country-based reference data
• Exploits the LOD resources to provide enhanced country profiles in Food and Agriculture.
• Exposes FAO Country Profiles data in RDFa to improve search and reuse
22FAO Country Profiles
Next steps
• Continue to provide high quality country information
• Add more LOD resources• Include the FAO geopolitical ontology in the
LOD cloud • Expand the FAO geopolitical ontology with
more data• Provide a SPARQL end-point
