Re: [ANN] Nemo (i.e. why I wrote Nemo)

Damian,

Thanks for the clarification.  I don't think I every
really had a good grasp on how treehugger or RDFTwig
worked, I guess.  I'm sorry for spreading
disinformation.  ;-)

Consider myself corrected.

That's impressive.  If it's a public model, mind
sending me the link?  Nemo could use some more
testing.

What I mean is something like:

<document>
  <metadata>
    <!-- rdf data -->
  </metadata>
  <body>
    <!-- document text -->
  </body>
</document>

That's the inital reason why I was looking into
RDF-in-XSLT support in the first place.  I could use a
pipe, but I wanted to do querying directly in the
transform stage.

I also felt that the approaches of querying documents
by treehugger and RDFTwig were complicated, while RDQL
just clicked in my head.  In my mind, I think in RDF
very differently than with XML's model.  The path-like
approaches just didn't make much sense to me.  Now, I
think I understand where you are comming from. 
However, I still perfer RDQL (it is how I think).

Ack!  I can see where it is useful, but I'd rather
keep transformation neatly seperated from the querying
specification.

Sounds interesting.

Thank you.  I'm sorry for spreading disinformation.
