This is an old problem that has always remained impossible to translate to RDF. In RDF there is only one relation, one "link" from a node to another. There cannot be 2 different relations with the same name. > I wonder, does RDF* change anything in regard to this behavior? I guess it does not but... I'd still like to ask anyway.
