    <rdfs:label>Vamp Plugins Ontology</rdfs:label>
    <rdfs:comment>
			Vamp Ontology. This ontology includes the following descriptions:
			
				- OWL description of the Vamp API
				- OWL description of the Transform environment necessary to set up the execution of any plugin 
			
			This Ontology provides semantics to describe and control Vamp plugins in RDF. Any "RDF-speaker" host is therefore able to 
			use this ontology to read, set up and execute plugins.
			The extracted features are expressed in terms of the Audio Features Ontology: http://purl.org/ontology/af/.
			For more information, please visit the Vamp Plugins website: http://www.vamp-plugins.org/

    <rdfs:label>Vamp Plugin output descriptor</rdfs:label>
    <rdfs:comment>
		Descriptor for an output of a plugin. This descriptor provides information that is necessary to correctly interpret the output features. The output type will determine how to read the temporal information of the extracted features and how to manage the burden of ouput data.

  <owl:Class rdf:about="TrackLevelOutput">
    <rdfs:label>track level output</rdfs:label>
    <rdfs:subClassOf rdf:resource="PluginOutput"/>
    <rdfs:comment>
		Specific output type for track level information.  The Vamp API does not provide for this sort of output directly, so this will require a "hacky" interpretation of the feature timestamp to establish that it reflects track metadata instead of temporal data.
