And I did mine more recently (2010) [1] :) (Mostly semantic web stuff ... showing how it can far outperform Java based SPARQL implementations for some stuff).

And I did mine more recently (2010) [1] :) (Mostly semantic web stuff ... showing how it can far outperform Java based SPARQL implementations for some stuff). It was a real joy to work with semantic web data in SWI-prolog! Prolog lets you raise your level of abstraction so quickly, as defining prolog rules basically is a form of creating "named queries", something that is not possible e.g. in SPARQL (the canonical semweb query language). I can't understand why this feature of prolog is not implemented more widely in more recent systems. The only example I know of that does, is Datomic [2], by Rich Hickey.
