I had the opportunity to do a short talk at the latest Semantic Web Dallas meetup
. I decided on an overview of the 303-redirect dance that differentiates a URI that points to a web page from a URI that names a concept in the Semantic Web. Yes, there's a difference. Yes, it's an important difference. Probably. In any case, it's a good topic for a 10-minute talk because having to listen to stuff like this for more than ten minutes at a time can lead to bleeding from the ears. It's a complex issue with an, uhh, unexpected? solution, best approached with a sense of humor. Well, maybe not best
approached that way, but it seemed like a good idea at the time. And the list of references at the end is pretty good.
If you read the references you'll learn that you can also use URLs with fragment identifiers in your RDF. But doing it that way doesn't involve a fundamental redefinition of part of HTTP so it's a lot less entertaining.
