Sitting on the sideline, as a software developer who earns a living developing software, it is interesting to observe the somewhat opposing points of view between Danny Ayers and Adam Bosworth on the principles of simplicity and where RDF fits in the grand scheme of things. I hold both of these guys in high respect (I garner much value from their blogs) but in this case I am leaning towards the Bosworth point of view. I am enamoured with the RDF concept, but realistically it is a royal PITB to implement anything on top of it, at least on the Java platform. Surprisingly, I think the concept may be too sloppy - lots of hand waving about what it is you are actually describing, and soothing but none-the-less high level abstractions. So, in accordance with Pareto I think I'll pass for now until someone smarter than me makes it more accessible.
