+    <rdfs:label>The Audio Features ontology</rdfs:label>
+    <dc:description>
+		This ontology expresses some common concepts
+		to represent automatically extracted features
+		from audio signals. Therefore, it mainly relies 
+		on the Event ontology, in order to classify particular
+		parts of the timeline backing an audio signal. 
+		
+		Programs outputting RDF according to this ontology should 
+		also describe the ouputted document to express some information
+		about itself (estimated confidence, maintainer of the program, etc.)
