Conversion from RSS to RDF

I don't quite understand RDF, but I am looking to convert RSS feeds from places like yahoo and google into RDF format to display on a website.

Any advice/help would be greatly appreciated.

Thanks!

Update: it seems I need to understand XS开发者_高级运维TL and stuff like that.

RSSOwl implements both RSS and RDF. It's open source.

Some of the RSS variants are RDF compatible :

So one solution could be to convert the other RSS variants via XSL-T to an RDF compatible version (e.g. 1.0).
