hi,

this problem also occurs with the categories and skos:broader. 
all concepts are soley connected with broader - there's no such 
property like narrower - i thought it was done for saving triples,
but you have to rewrite certain queries and sometimes formulate
like http://dbpedia.org/resource/Yoda would.

check out http://dbpedia.org/page/Category:Fictional_sword_fighters for an 
example.

consider the following when adjusting your query :

- the underlying query of http://dbpedia.org/page/something is apparently a 
describe query.
- if you see a is...of the on a page the subject of that triple has changed.
  i.e.
  resource      x
  broader       x skos:broader y
                x skos:broader z
  is broader of a skos:broader x
                b skos:broader x

Subject: [Dbpedia-discussion] How to query "is <propertyName> of" by SPARQL


Hi All, 

I'm new using SPARQL and try to query some information using dbpedia. I got 
problem when i try to query a property value which started with is ... of. For 
Example when i access this page : dbpedia.org/resource/Coffee , it display is 
dbprop:exportGoods of ..... 
However, when i try to access the value of this property using sparql it does 
not give any result. I try the other property without is..of and the query can 
give the results. 

What's wrong with my query? 

Thank you for your help. 

regards, 
Hendrik
