rdf parser for DAML+OIL

Hi all

please could you provide me some help with writing W3C::RDF based RDF
perl parser
I tried few other RDF parser perl libs
but none of then support daml:collection parseType
as I see from CVS messages for perllib - something was made on this
way

please can you help me writing simple triple extractor based on
W3C::RDF lib

I've tried use parser example from W3C/RDF/Parser.pm and W3C/RDF/RDFParser.pm
and got this error:

Can't locate package W3C::Database::DBIRef for @W3C::Rdf::Algernon::ISA at C:/Pr
ogs/prog/Perl/site/lib/W3C/Rdf/RdfDB.pm line 652.
<W3C::Util::Exception=HASH(0x254e578)> Can't bless non-reference value at C:/Pro
gs/prog/Perl/site/lib/W3C/SAX/HandlerBase.pm line 27.
Can't locate package W3C::Database::DBIRef for @W3C::Rdf::Algernon::ISA.
Can't locate package W3C::Database::DBIRef for @W3C::Rdf::Algernon::ISA.

it seems that I need all W3C perl modules to run W3C::RDF

Thank you for your answers
