LANG: owl:Ontology

There is no requirement that an RDF document have a root element <rdf:RDF>.
Particularly because OWL may be used, or make have interpretations that go
beyond the base RDF (e.g. OWL is colloquially 'layered' on RDF, use of a
distinct root element e.g. <owl:Ontology> is a clearcut signal to interested
OWL processors, that the contents are OWL.


<owl:Ontology xmlns:owl="...">
    <rdf:Description rdf:about="...">

    <owl:Class rdf:ID="bar"/>

is perfectly legal RDF and good practice.
