(Though here perhaps comes in between the fact > that search engines prefers to help us locate HTML pages rather than > feeds.) I mean using an RDF processor, and treating it as an RDF graph. Everything just creates from an XML stream (or object model) a bunch of items with a certain title, date, and description, and acts on that (and parses it out in a format specific manner, so it creates the same sort of item for, e.g., Atom) ? it doesn't actually use an RDF graph for it. If you can find any widely used software that actually treats it as an RDF graph I'd be interested to know. -- Geoffrey Sneddon <http://gsnedders.com/> <http://simplepie.org/>
