Changing permanent uris (RDF)
While running through my backlog of comments, I found out that the RDF category was being served up as pure RDF thanks to my rewrite rules. (Thanks to this comment).
While it seems appropriate that you can only get RDF-related posts in RDF, I bowed to the wisdom of Mr. Ayers and fixed that. This has the side effect of changing the uris. The category is now called PlanetRDF, to reflect the ultimate destinations of said posts.
Please don’t kill me if it confuses your feed reader; the timestamps and other metadata have not changed.
