I just came across this 3-dimensional representation of the Semantic Web Layer Stack – or cake- handcrafted by Benjamin Nowack. The author also links to Jim Hendler’s talk on the Semantic Web Layercake (from 2009), possible the world’s first Semantic Web talk completely in rhyme. Jim’s talk gives a good overview of the evolution of the Semantic Web and how an incredible number of icing, sprinkles and candles was added to the layercake over the years.
The complexity of the stack – both the ‘simplified’ version and the more elaborate one in Jim’s talk – makes me wonder how usable the Semantic Web approach really is. Will there be a point where the technologies converge, some die, others emerge as winners? Or will we live happily with a big messy cake that’s got a little something for everyone?
