Hi,
the properties in the namespace http://dbpedia.org/ontology will all be
included in the dbpedia ontology.
The others can be found here:
http://wiki.dbpedia.org/Downloads36
http://downloads.dbpedia.org/3.6/en/infobox_property_definitions_en.nt.bz2
The query you mentioned:
http://dbpedia.org/snorql/?query=select+distinct+%3Fproperty+where+{%0D%0A+++++%3Fs+%3Fproperty+%3Fo+.%0D%0A}+Limit+10%0D%0A
does indeed not seem to work. The error being:
Virtuoso S1T00 Error SR171: Transaction timed out SPARQL query: define
sql:big-data-const 0 #output-format:application/sparql-results+json
define input:default-graph-uri PREFIX owl: PREFIX xsd: PREFIX rdfs:
PREFIX rdf: PREFIX foaf: PREFIX dc: PREFIX : PREFIX dbpedia2: PREFIX
dbpedia: PREFIX skos: select distinct ?property where { ?s ?property ?o
. } Limit 10
It might only be a temporary/maintenance bug.
Best Regards,
Sebastian

Hi,
I want to extract all properties from the DBpedia data set and I tried
the following query but it did not work. I even tried to limit the
results but still it did not work as well.
select distinct ?property where {
?s ?property ?o .
}
I have the properties defined in the DBpedia Ontology but I am
wondering whether their can be some other properties not defined in
the ontology. If somebody can help me it would be a great help.
Thank You
Best Regards
