[Rdfapi-php-interest] RDQL - Query with sameAs

[Axel H. <a_...@we...>]

Hello,

 

i am new to rdfapid and have a little question. How can rdfapi use the
property "sameAs" ?

 

In my Test case, i've an class "superclass1" and "superclass2". 
superclass1 is defined as "sameAs superclass2" and superclass2 is defined as
"sameAs superclass1"

 

A third class is "subclass1" and is defined as "subClass of superclass1" 

 

The following query gives me subclass1 as result:

 

SELECT  *  WHERE (?x, rdfs:subClassOf, <http://myUrl/test#superclass1>)';

 

Why do i not get the same result with

SELECT  *  WHERE (?x, rdfs:subClassOf, <http://myUrl/test#superclass2>)';

when superclass2 is the same as superclass1 ?

 

Is there a possibility to achieve that?

 

Thanks for your help.

Best regards

Axel
