The Parser works fine when the author is a person, but breaks when the author is an organization.
For instance, In the test rdf I used, an organization is in the author
<bib:authors>
<rdf:Seq>
<rdf:li>
<foaf:Person>
<foaf:surname>Center for History and New Media</foaf:surname>
</foaf:Person>
</rdf:li>
</rdf:Seq>
</bib:authors>
In this case, the reader breaks.
