Re: cwm does not understand the typed-node-as-root idiom?

Sean seems correct, that cwm does not find any rdf in that file.
However, cwm can use rdflib as a parser (if it is installed). That seems
to work to parse that file. What you need is either to set the
environment variable


or use cwm --rdf=rdflib
'http://www.codezoo.com/cs/user/run/component/5576?x-r=doap' --n3

(the second is a brittle hack, interpreting parsing flags as a string,
and is not very recommended)

It's been a long time since I read the RDF spec and tried to update
cwm's parser to match it. The set of failures from the official test
suite is at http://www.w3.org/2000/10/swap/test/testmeta.n3 . Obviously,
this is not covered.
