Hi Nathan, I used this as my starting point: http://www.openarchives.org/OAI/2.0/rdf.xsd which is the structure to include rdf in the OAI protocol
I derived from that that construct needs to have the following form: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xsi:schemaLocation="http://www.w3.org/1999/02/22-rdf-syntax-ns# http://www.openarchives.org/OAI/2.0/rdf.xsd";> </rdf:RDF:> Then I probably made a mistake by replacing http://www.openarchives.org/OAI/2.0/rdf.xsd with http://creativecommons.org/ns# instead of replacing the first http://www.w3.org/1999/02/22-rdf-syntax-ns# I am equally not sure about the schemalocation. Probably the right way to use ccREL here is: <rdf:RDF xmlns:cc="http://creativecommons.org/ns#"; xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xsi:schemaLocation="http://www.w3.org/1999/02/22-rdf-syntax-ns# http://www.openarchives.org/OAI/2.0/rdf.xsd";> </rdf:RDF:> Would you agree?
