query through web API

hello,

i have a homegrown perl RESTful RDF API which is rather like joseki,
but meant for model-annotation[0]. past versions of it have had specific
common queries hardcoded, with variables in a GET query string to be
dropped into the slots of SquishQL queries (more homegrown perl).       

- i'd like to be able to GET the RDF graphs corresponding to
arbitrary SquishQL results, returned as XML, just like in
http://www.joseki.org/protocol.html 
But I'm banging my head against being able to change the tabular data that
i get back from Squish, into bucket-o-triples form, programmatically.

e.g. in my existing code i wind up doing things like this: 

    my $q = qq( SELECT ?pred, ?object
                WHERE
                ('$id' ?pred ?object)
        	);
    my @bits = $self->rdf->query($q);
    @bits = map { [$id, $_->[0],$_->[1]] } @bits;

(then the array of arrays goes straight into a serialiser...)

am i making myself clear, re, being able to map back the tabular data into
the graph without intervention? 
i wonder how joseki does this, with RDQL
i wonder if there's a better way
     
- also i'd like to be able to cache the queries inside the model, and
refer to them with URIs... i thought this was a kludgy idea until i read
the HTTP POST section of that joseki protocol doc... perhaps it still
is... i would wind up describing the API inside the triplestore.


yours, confused,
metazool
