When loading rdf/xml like:

...
<documents:jurisdiction rdf:resource="http://rdf.muninn-project.org/ontologies/documents#US_Copyright_Act_of_1909"/>
documents:date_published
<time:before rdf:parseType="http://www.w3.org/2001/XMLSchema#gYear">1920/time:before
/documents:date_published
...

with

$parser->parse(the_file.rdf);

generates

...
<ns0:jurisdiction rdf:resource="http://rdf.muninn-project.org/ontologies/documents#US_Copyright_Act_of_1909"/>
<ns0:date_published rdf:nodeID="arce720b1"/>
/rdf:Description

<rdf:Description rdf:nodeID="arce720b1">
<rdf:type rdf:resource="http://www.w3.org/2006/time#before"/>
/rdf:Description

The '1920' and gdate are lost lost.

Interestingly, parsing of "rdf:parseType" is case sensitive and the parsers drops information unless 'parsetype' is in lower case:

<documents:Image rdf:about="http://rdf.muninn-project.org/ww1/2011/11/11/Image/e73684a85eda5e96189b2cff8c85d814">
<documents:date_retrieved rdf:parseType="http://www.w3.org/2001/XMLSchema#date">20120215/documents:date_retrieved
/documents:Image

get munged to

<rdf:Description rdf:about="http://rdf.muninn-project.org/ww1/2011/11/11/Image/e73684a85eda5e96189b2cff8c85d814">
<rdf:type rdf:resource="http://rdf.muninn-project.org/ontologies/documents#Image"/>
/rdf:Description

but

<documents:Image rdf:about="http://rdf.muninn-project.org/ww1/2011/11/11/Image/e73684a85eda5e96189b2cff8c85d814">
<documents:date_retrieved rdf:parsetype="http://www.w3.org/2001/XMLSchema#date">20120215/documents:date_retrieved
/documents:Image

gives

<rdf:Description rdf:about="http://rdf.muninn-project.org/ww1/2011/11/11/Image/e73684a85eda5e96189b2cff8c85d814">
<rdf:type rdf:resource="http://rdf.muninn-project.org/ontologies/documents#Image"/>
ns0:date_retrieved20120215/ns0:date_retrieved
/rdf:Description

I haven't tracked down what makes the date datatype disappear but that seems to be another issue.

rdf:parseType is a reserved attribute that can take the values "Resource", "Literal", or "Collection". Do you perhaps mean rdf:datatype?
