This program allows the creation of a service delivering RDF (designed
according to the chord ontology available at http://purl.org/ontology/chord/)
description of chord symbols, formatted using Christopher Harte's notation
(Harte, 2004, ISMIR).

Then, for example (if the service is available at http://purl.org/ontology/chord/symbol/, which 
is the case):

$ curl -L -H "Accept: application/rdf+xml"  "http://purl.org/ontology/chord/symbol/G:min(9)/b3"


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE rdf:RDF [
    <!ENTITY ns1 'http://purl.org/ontology/chord/'>
    <!ENTITY rdf 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'>
    <!ENTITY xsd 'http://www.w3.org/2001/XMLSchema#'>
]>

<rdf:RDF
    xmlns:ns1="&ns1;"
