Still not getting it, here's your second example in that syntax:
SELECT ?son WHERE
{
<brian> parentOf ?son
?son gender <male>
}
What's the fundamental difference? That one example yields a new RDF triple, and the other yields a query result? Surely this is just a matter of representation.
- bct 19y agoGood point. I think you've changed my mind about the utility of inferencing :). The difference between querying and inferencing isn't what I was trying to emphasise, though. My point was the difference between being designed for making queries/inferences within a dataset, and being designed for joining distinct datasets. Querying within a dataset is easy: SQL, XPath, XQuery, LINQ, etc. You can write rules for transforming any data model that you can query. RDF isn't anything special in these areas (though I do think that SPARQL is an awfully nice query language). What it gives you is a way to link and merge datasets.
