Detailed Description

FocusNode is a convenient class that treat a uri in a RDF graph as the root of an object with properties.

For instance for the following RDF Graph:

<a> a <object_type> ;
    <property_1> "property value 1" ;
    <property_2> "property value 2" .

The property values can be manipulated by creating:

FocusNode a("graph_uri"_kCu, "a"_kCu, Registry::get("object_type"));
