SPARQL query returns no results when a property path is present -

-

The following query returns some results which are scots: detailed set as category: History 

 < Select code> Subject where {? Subject skos: wide range: history}

though instead of skos: with sketch: broader + or skos : Broader * gives no results. Why is it like this? I hope that at least the first query will be the official candidate to get the given results.

I am using SPARQL front end here:

all does not support this may be such a case Where you have participated in some internal borders, you can guess the results that you want from a query like the following, however: 

  select? Category {? Category} skos: Broad {, 7} Category: History}

It only follows the path of length seven or less {m, n} Nation for the property path is not part of SPARQL 1.1, But the initial draft was in, and the virtuoso supported it in questioning the question is convenient to limit the resources used, and this is a good use case.

Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
