Hi Nikita
I remember something from my Relational Algebra; as well as 3-NF data
Here is a good URL:

Emne: property inference rule

Does anybody know a way to express 
an inference rule that from:
<person rdf:ID="A">


            <hasDaughter rdf:resource="#C"/>

<person rdf:ID="A">

    <hasNiece rdf:resource="#C">
In other words:
{hasNiece} = {hasBrother X hasDaughter}
I had been pondering over this for some time
and could not find an answer neither myself nor by asking some other
