Obtaining information from is dbp: ... of

Question

I am trying to get some information of the DBpedia page of Rodger Federer. I want to query in which years Roger Federer was flagbearer at the Olympic Games. I can extract information from normal property fields (dbp:plays), but not if the property is of the format (is dbp:flagbearer of).

Can someone give me some advise how to extract the years in which Roger Federer was flagbearer and possibly give a query?

do you know the required predicate for that flag bearer or the class of the winner ? I came up with this query `select * where { values ?you {} ?you ?o }` check if it has some interesting values for you — William Kinaan, Apr 19 '16 at 16:01
Unfortunately it does not yield any interesting values. Any other advise? — Henry Maathuis, Apr 19 '16 at 16:29
no I'm sorry .... I'm not so familiar with the tense vocabularies — William Kinaan, Apr 19 '16 at 16:51

You can get that information using the following query.

PREFIX dbp:<http://dbpedia.org/property/>

select ?olympics ?year where { 
   ?olympics dbp:flagbearer <http://dbpedia.org/resource/Roger_Federer>;
             dbp:games ?year .
}

This query will give you the following results in DBpedia.

+---------------------------------------------+------+
|                  olympics                   | year |
+---------------------------------------------+------+
| dbr:Switzerland_at_the_2008_Summer_Olympics | 2008 |
| dbr:Switzerland_at_the_2004_Summer_Olympics | 2004 |
+---------------------------------------------+------+
