Hello Peter,
I see that somebody has made a permanent declaration of namespace prefix
"ns:go" for "http://bio2rdf.org/ns/go#";, should be just "go", if any.
That can be checked by looking at DB.DBA.SYS_XML_PERSISTENT_NS_DECL (to
check whether persistent declaration is recorded), but this seems not to
be a case because __xml_get_ns_prefix ('http://bio2rdf.org/go#', 3)
returns nothing. I've checked all my sources for "bio2rdf.org" string
and found nothing. Virtuoso pre-sets some popular namespaces prefixes,
in function DB.DBA.XML_LOAD_ALL_NS_DECLS(), file libsrc/Wi/sparql.sql,
but it does not define this bio2rdf prefix, moreover it defines prefix
"go" for http://purl.org/obo/owl/GO# .
So I'm sorry I can't help much.
Best Regards,
Ivan.
