Hello Mitko,
i think it is Curran's test-query and aims all properties, and not
only dbpedia-onto prop's which are defined in the dataset, but anyway
i think we take it only as a test-query to understand how the engine
works, would i say... Baran.

Without 'distinct' it does work:

Why might this be?
So you are asserting that for a given data space hosting N named graphs
(named collections of triples) :
select ?property where {

Hi Kingsley,
Specifically, each solution that binds the same variables to the same RDF
terms as another solution is eliminated from the solution set. This sounds
like a first encounter would be added to the result set, and any subsequent
encounters would simply not be added to the result set.
Hi Sarasi,
I've performed that query with limit 1000, and it worked on one of our
local endpoints, and it ended within 3 minutes.
So I guess that the maximum time allowed for a query on the official
endpoint is relatively low, but the query itself is executable with limit.
Hope that helps.

Hi Kingsley,
Thanks for your clarification, but I don't understand why 'first encounter
!= distinct'. I was thinking that DISTINCT just causes duplicate solutions
to be excluded from the result set, just like DISTINCT in SQL. The SPARQL
reference states

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
Hi,
the properties in the namespace http://dbpedia.org/ontology will all be
included in the dbpedia ontology.
The others can be found here:
