Practical use (and reuse) of CONSTRUCTION clause

Question

When used CONSTRUCTin a sparql query, the output is a single RDF graph , as well as a set of triples, which are essentially new data, but in general, I thought that was CONSTRUCTa way to manually create a rule that theoretically should be reused.

---

In a usage example CONSTRUCT, let's say I wanted to define what was not yet in the data. Here is a good example taken from an article about CONSTRUCT .

@prefix : <http://some.site.com/ont#> .

:jane :hasParent :gene .
:gene :hasParent :pat ;
      :gender    :female .
:joan :hasParent :pat ;
      :gender    :female . 
:pat  :gender    :male .
:mike :hasParent :joan .

"The following CONSTRUCT statement creates new triples based on the above to indicate who the grandfather is:"

PREFIX : <http://some.site.com/ont#>

CONSTRUCT { ?p :hasGrandfather ?g . }
WHERE {?p      :hasParent ?parent .
       ?parent :hasParent ?g .
       ?g      :gender    :male .
}

and the result:

@prefix :        <http://some.site.com/ont#> .
:jane    :hasGrandfather    :pat .
:mike    :hasGrandfather    :pat .
