this is problem in the raptor "rdfxml-abbrev" serialization that was
reported recently.
it is fixed in CWS sw34bf03, which is not yet integrated, but will likely
go into OOo 3.4.
you can track the progress of this CWS here:
http://eis.services.openoffice.org/EIS2/cws.ShowCWS?Path=DEV300%2Fsw34bf03
to fix it i've switched to the "rdfxml" serialization, which does not seem
to suffer from this bug.
it also creates even more verbose files...

[dev] Re: RDF metadata, unable to read ?
I think i found a bug in the rdf implementation -- the problem seems
to manifest if i give a particular kind of URI --
If i use this format "http://www.xyz.org/1.0"; as the URI for the rdf
graph while saving :
Dim uriAnx
uriAnx = UriService.create("http://editor.bungeni.org/1.0"; )
Dim rdfMetafile
rdfMetafile = odoc.addMetadataFile("meta/meta.rdf", Array(uriAnx))
In the above case the URI namespace is not recorded in manifest.rdf.
If i use this format "http://www.xyz.org/1.0/abc"; as the URI for the
rdf graph while saving :
Dim uriAnx
uriAnx = UriService.create("http://editor.bungeni.org/1.0/anx"; )
Dim rdfMetafile
rdfMetafile = odoc.addMetadataFile("meta/meta.rdf", Array(uriAnx))
It works fine and I am able to browse the graph names in the repository.
In this case the URI namespace is recorded in manifest.rdf
Is this a bug or valid behavior ?
The documentation is a bit ambiguous on this
