Obviously it is the element "RDF" in the "rdf"-Namespace. This applies
for all RDF data in XML. The root element is not important because RDF
data consists of triples not of a tree.

The first triples are:

http://www.fao.org/aos/agrovoc
http://www.w3.org/1999/02/22-rdf-syntax-ns#type
http://www.w3.org/2004/02/skos/core#ConceptScheme

Saying: http://www.fao.org/aos/agrovoc is a ConceptScheme

http://www.fao.org/aos/agrovoc
http://purl.org/dc/elements/1.1/title
"AGROVOC"

Saying: dc:title of http://www.fao.org/aos/agrovoc is "AGROVOC"

..and so on (dc:creator is a bit tricky because there are anonymous nodes).

You can analyze SKOS-Data at the XML-Level (for instance with XSLT) or
at the RDF-Level (triples).

Greetings,
Jakob
