Someone pointed me to the blog Jeni's Musings, written by Jeni Tennison. I don't know who Jeni is, but there's some really interesting stuff here, with some obvious links to UK Government Data activity. Among other things, there's a post about expressing statistics with RDF (it looks pretty horribly verbose, but it's the first attempt I've seen to address some real data that could be relevant to science research), an thoughtful post about the provenance of linked data, and a series of 5 posts (from here to here) on creating linked data.
