Getting RDF data into HTML

Hi everyone.  I've been lurking for a couple of months while my interest
in RDF has been swelling.

I have some RDF which describes TV shows and films I have seen and short
reviews or thoughts about them.  This is the file of reviews

  http://mcc.id.au/sw/reviews

and this is the RDF schema for my review namespace

  http://mcc.id.au/sw/schema/reviews-1.0

.  Firstly, some questions about how my RDF.

1. Is it OK that I have chosen URIs to identify my re:Movie and
re:Episode objects?  For example, for a movie I'll use the imdb.com URL
for that movie, and for an episode I might use the geos.tv page.  Or
should I be using URIs that are under my control?  What if, in the
future, it is decided that a different URI is the accepted standard for
identifying movies and TV episodes?

2. Am I right in thinking that the URIs I used to identify the re:Movies
and re:Episodes do not necessarily have to have any information at them
if dereferenced, and that it is a good idea to have the re:webpage
properties as I do?

Now, I'd like to make a web page that lists the shows I've seen in
reverse chronological order.  I found myself the Redland Perl modules
and wrote a script which does that.  You can see the script at

  http://mcc.id.au/temp/viewings.txt

(the executable script is at

  http://mcc.id.au/cgi-bin/viewings.pl

).  I find it terribly verbose to look up information.  For example, if
I have a show in $show and I want to find its title, I have to do

  my $titleStatement = new RDF::Redland::Statement($show, $DCTitle, undef);
  my $title = ($model->find_statements($titleStatement))[0]->object()->as_string();

Similarly for all the other properties I want to retrieve.  I realise
that if there was a query language here where the variables could be
filled in with a single function call, then it would be a step in the
right direction.

The other problem though is that of generating the XHTML.  I feel like
there should be something akin to XSLT for generic XML data that can let
me declaratively transform RDF data into XHTML.  Does such a thing exist?

Can anyone provide any other hints on how they have turned RDF data into
XHTML?

Thanks,

Cameron
