You could use http://likn.org/owl/" as the default namespace - e.g.:

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
	xmlns:dc="http://purl.org/dc/elements/1.1/"
	xmlns="http://likn.org/owl/"
	xml:base="http://likn.org/rdf/">
	<rdf:Description rdf:about="becca">
		<dc:title>Becca</dc:title>
		<rdf:type rdf:resource="http://likn.org/owl#person" />
		<eyeColor rdf:resource="brown" />
		<eyeColor rdf:resource="green" />
	</rdf:Description>
</rdf:RDF>

or just use n-triples - e.g:

<http://likn.org/rdf/becca> <http://likn.org/owl/eyeColor>
<http://likn.org/rdf/green> .
<http://likn.org/rdf/becca> <http://likn.org/owl/eyeColor>
<http://likn.org/rdf/brown> .
<http://likn.org/rdf/becca> <http://purl.org/dc/elements/1.1/title> "Becca"
.
<http://likn.org/rdf/becca>
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
<http://likn.org/owl#person> .
