Technical Ramblings

So, I implemented SPARQL CONSTRUCT queries in Julie yesterday (http://crschmidt.net/noets/115) along with ASK queries (http://crschmidt.net/noets/114). Really, the CONSTRUCT queries are pretty silly to have: who wants to see serialized triples on an IRC interface? but I was thinking: what if instead of spitting the triples into IRC, it sent them into the backend?

I’m sure that the people in charge of SPARQL thought of this long ago, but it just occured to me, that this is a simple way to achieve rules-like processing:

10:49:36 <crschmidt> ^q CONSTRUCT { ?a rel:childOf <http://crschmidt.net/foaf.rdf#crschmidt>. } where { <http://crschmidt.net/foaf.rdf#crschmidt> rel:parentOf ?a. }
10:49:37 <+julie> {[http://crschmidt.net/~julie/me.rdf#julie], [http://purl.org/vocab/relationship/childOf], [http://crschmidt.net/foaf.rdf#crschmidt]},
{[http://crschmidt.net/~alicia/me.rdf#alicia], [http://purl.org/vocab/relationship/childOf], [http://crschmidt.net/foaf.rdf#crschmidt]}

Feeding these kind of results back into julie could let people create the equivilant of rules, passing them back into julie to add to the triplestore.

Man, I thought I gave up on this RDF stuff. Looks like maybe I wasn’t as done as I thought I was.
