Of course Sean is dead wrong as to the salient matter, but he’s always a good read. RDF is for people who understand directed graphs. If you take any random audience, this is, of course, a small proportion. Same story for forensic histology, but I doubt Sean would moot for closing down all the crime labs. The argument that “not everyone can get RDF ” is not worth any number of words. The more interesting point is that anyone who can’t get RDF can’t get relational databases or any other sort of formal information modeling, and they can’t get code (both flow of control and declarative algeras are graphs more complex than RDF). For those outside this set, as Sean points out too obliquely, there are plenty of tools and they needn’t deal with RDF directly.
