*shrug*
I’ve been deploying REST/RDF solutions since 2004 (and playing with it years earlier than that). Neither part was rocket science, but both required looking at typical engineering problems in a holistic way in which the impact of change over both time and space were accommodated up front. You get an amazing amount of stuff “for free” (as in beer) with such an architectural style, so I had no problem at all paying Winer’s “RDF tax”.
And beware profiles. LDBP is not a protocol, it’s a conformance statement on implementations and as such is meaningless to developers of client software.
