Hi all,
I am trying to learn more about the Semantic Web, in particular SPARQL
thus I set out on a simple task; to list all the countries in the World
that are currently classed as such and then get a cumulative population.
Should get around 200 countries and about 7 billion people in the end I
assumed.
http://octogo.co.uk/cw/ shows my progress so far, I have got ~840 URI's,
some are mislabeled in Wikipedia with Country Infoboxes which is fine (I
have corrected a couple of these but obviously not synced), but others
are marked up with Infobox Former Subdivision which according to my
calculation should map to the AdministrativeRegion class,
http://mappings.dbpedia.org/index.php/Mapping:Infobox_former_subdivision. Does
anyone know why they are appearing in this query?
PREFIX dbo:<http://dbpedia.org/ontology/>
PREFIX dbp:<http://dbpedia.org/property/>
select distinct ?country
where {
?country a dbo:Country .
OPTIONAL { ?country dbo:dissolutionYear ?x } .
FILTER (!bound(?x))
}
ORDER BY ?country
In particular:
* http://dbpedia.org/resource/Acadia
* http://dbpedia.org/resource/Erina_Shire
* http://dbpedia.org/resource/Viipuri_Province
Many thanks,
Alex
